Ceramic pressure sensors are utilized in a variety of ways across numerous industries – but not all sensors are created equal. While all serve the function of measuring the pressure of liquids and gases, their applications range as far as measuring oil levels in the automotive industry to supporting life-saving medical devices.

Ceramic sensors can operate in harsh environments with extreme pressure and temperature factors at play due to their robust, stable, and cost-efficient nature. They are also valuable in applications where harsh chemicals may be present. As such, ceramic pressure sensors often present the best solution for difficult measuring applications. Many types of ceramic pressure sensors exist to address a broad range of challenges in numerous industries.

Types of Ceramic Sensors

Servoflo offers a wide range of ceramic pressure sensors that can be used to measure pressure rates or fluid levels. From full transducer packages to smart metering systems, our range of ceramic sensors provides solutions for every potential application.

Flush Mount vs. Monolithic

Flush mount sensors are flat, smooth, and feature no dead volume of media pressure. Monolithic sensors, on the other hand, have an indentation in the side that is exposed to the pressure media. Flush mount solutions from Servoflo offer a wider range of pressure tolerances, from 0.5 bar to as high as 600 bar.

Which sensor you choose will be determined by your application requirements, as flush and monolithic mounts each have strengths in different areas. For example, a flush mount would be ideal if sealed gauge or absolute sensors are required by the application, while monolithic sensors are often ideal for a range of industrial automation or process control applications.

Piezoresistive vs. Capacitive

Servoflo's Metallux line of ceramic pressure sensors are, either piezoresistive or capacitive by nature. Both are resistant to corrosion and are compatible with a wide array of environmental conditions and are suitable for various industrial, automotive, or medical applications.

Capacitive sensors are often preferred for applications that feature high overpressure values but also require accurate low pressure measurement or high resolution measurements.

Differential Pressure Sensors

The ME800 ceramic differential pressure sensors measure differential pressure using a single sensor rather than two. This saves on cost and improves accuracy by narrowing down the possibility of error. Should errors occur, a single sensor makes them easier to pinpoint, which helps you to repair, replace, or recalibrate equipment quickly and limit costly downtime.

Amplified vs. Unamplified

If you'd prefer to calibrate and amplify your own sensors, we offer sensors with a millivolt of output that provides a blank slate for your design. This option gives you the freedom to amplify your own transducer signal and allows you to maintain control over both pressure range and output frequency.

For users who don’t require advanced customization or are simply seeking a standardized solution, we also have calibrated, temperature-compensated sensor models that are amplified and ready for use. We can provide ratiometric, non-ratiometric, current loop, and I2C sensors that integrate directly into existing systems and provide a wide range of sensitivity suitable for myriad applications.

Ratiometric vs. Non-Ratiometric

Amplified units consist of ratiometric and non-ratiometric sensors. Which of these two models will be appropriate depends largely on the voltage requirements of the application. Generally, lower voltage applications (0.5V to 4.5V) should choose a ratiometric sensor, while applications that use 12V or more should use a non-ratiometric sensor.

Choosing the incorrect solution for your voltage requirements will impact the reliability of digital conversion readouts.

Ceramic Pressure Sensor Sizes

Servoflo's sensors come in a variety of sizes, ranging from 9 mm (model ME900) in diameter up to 32.4 mm in diameter. The 9 mm sensor is an exciting addition to the Servoflo line of pressure sensors because it provides an ideal solution for small spaces and applications which otherwise may have been too constrictive for simple installation. The 9 mm solution comes pre-calibrated and pre-amplified, so customers must only add a cable to begin using it.

Humidity sensors are an important piece of equipment in the medical, automotive, HVAC, and food production industries, among others. Any industrial facility that requires a controlled atmosphere requires a properly functioning humidity sensor. Whether your requirements for maintaining or reducing humidity levels are for safety, function, environmental control, or comfort, it's important that you choose the most appropriate sensor for the job.

Choosing a Humidity Sensor

By knowing what questions to ask when choosing a proper humidity sensor for your situation, you can ensure successful operation and longer life for your equipment. The first step is to know your budget and assess your needs. Some of the factors to consider here include:

• Size, accuracy, and interchangeability
• Long-term stability needs
• Repeatability requirements
• Required resistances of the sensor to any chemicals or contaminants it will be exposed to

It is also important to understand the different types of humidity sensors available to choose from.

• Resistive humidity sensors measure an electrical change that can be caused by a conductive substance. These systems use electrodes and AC excitation voltage to produce a data value for relative humidity.

• Thermal conductivity humidity sensors measure absolute humidity. They do this by calculating the difference in the conductivity of dry air compared to air that contains water vapor. These sensors use thermistor elements to form a bridge circuit and measure the difference in resistance.

Selecting the Right Humidity Sensor for Your Application

Choosing the most appropriate humidity sensor for your application can help ensure the cost-effectiveness and success of your project.

• Accuracy

The first aspect you should examine is the level of accuracy you need.  The more accurate the sensor needs to be, the higher the cost will be.

• Interchangeability

Cost can also be affected by the interchangeability of the sensor, which may cause vibration and lead to additional costs for calibration. 

• Condensation

If condensation is present, you may also need to factor in the cost of condensation resistant filters.

• Packaging

Package type can impact cost savings if you choose a combined humidity and temperature sensor instead of two separate sensors. 

• Power

Power consumption will have overarching long-term effect on costs.

Different applications will have additional considerations that must be reviewed.  Industrial applications have to consider the environment of the system and whether or not the sensor is resistant to chemicals or contaminants. For example, healthcare applications often require precise conditions and accurate, repeatable measurements, as well as the ability to maintain a clean environment. Similarly, humidity sensors are critical in HVAC and transportation applications to prevent excess moisture that fosters bacteria and mold growth. 

Other Important Considerations

When considering the purchase of a humidity sensor, there are a few logistical concerns that also need to be reviewed. Ask the following questions to help you narrow down the proper solution and provider: 

• What are the lead times of the supplier and will you get your parts in time?
• Does the supplier have a location close enough to provide in-person consultations and to deliver your product, or will the distance increase the lead time?
• Do you have second source requirements in the event of a supply chain issue?
• Can the supplier make a product unique to your specs or will they try to retrofit an existing product?
• Are they willing to share data and guarantee their accuracy with a warranty and service policy?
• Do they stand behind their products with technical support?
• How does the price compare to the rest of the market when you look at the component, consultations, and long-term service provided?

Humidity Monitoring Solutions from Servoflo

As you can see, there are many factors to take into consideration when selecting a humidity sensor.  Not only do you need to make sure you’ve selected the right one for your application, but you also need to make sure that you select the right company.

Servoflo has been providing sensor solutions to a broad range of industries and applications for nearly 20 years. To learn more about what it takes to select the best humidity sensor for your project, check out our eBook here.

Servoflo distributes a variety of capacitive and resistive humidity sensors for medical, HVAC, instrumentation, critical containment and other applications.  Some situations need precise and highly accuracy relative humidity (rH) measurement to maintain narrow, specific environmental conditions while others have a broad temperature range with wider tolerance ranges for rH measurement. This blog post explains the differences between capacitive and resistive relative humidity sensors and why to choose one type over the other.

Capacitive Sensors

Humidity and dew sensors, also called hygrometers, are necessary when consistent environmental conditions are required to be maintained.  A capacitive humidity sensor is so named because it uses capacitive measurement, which relies on electrical capacitance. These are a common type of humidity sensors.

The capacitive sensor is composed of two metal plates, or electrodes, separated by a thin layer of non-conductive polymer film.  The film attracts moisture from the air and when the moisture makes contact with the metal plates it creates a voltage change.  The output voltage measurement is captured and can be displayed via an analog dial, output into another system, or converted into a digital reading that indicates the amount of moisture in the air.

The capacitive sensor is contained in a hygrometer to measure relative humidity. The sensor is one part of the system that also contains a probe, cable, electronics, and an output signal.  Together they function to accurately measure the entire humidity range from 0% to 100%.

Resistive Sensors

Resistive sensors work on a similar principle to capacitive sensors, where electrical change is measured to produce a value for relative humidity. However, the mechanism in this system is different. Although resistive sensors use a hygroscopic (moisture-absorbing) material similar to the capacitive system, the difference is that the measurement is of the resistance change in the material rather than the capacitance. 

In this case, the output voltage has an inverse exponential relationship to relative humidity. As with capacitive sensors, the data regarding the output voltage can be captured, stored, or converted. These sensors use cost-effective, scalable dielectrophoresis, in which a free-standing structure is created to house pre-patterned electrodes that are separated by a single crystalline zinc oxide nanowire (ZnO NWs).

The benefit of a resistive sensor is the high surface-volume ratio, which allows it to measure humidity changes in the environment up to 90% relative humidity at room temperature. These systems do have limitations, and as such are not optimal for measuring values below 5% RH.  Applications that favor a resistive sensor include automotive, smart food packaging, and relative humidity sensor networks.

Selecting a Humidity Sensor

Although the capacitive sensor and resistive sensor have the same goal in measuring humidity, they differ in their methods.  Capacitive sensors are considered to be more accurate and stable while producing repeatable results—however, their cost can be prohibitive, making them more suitable for medical type applications where precision is paramount.  The less expensive resistive sensors are more practical for situations where frequent measurements are taken that do not require extremely precise data.

Industry professionals employ pressure sensors in a variety of applications, ranging from aerospace to oil and gas to utilities. In many cases, they are subjected to harsh operating and environmental conditions, such as high pressures, corrosive compounds, and temperature extremes. For use in these circumstances, ceramic pressure sensors are a suitable option.

Pressure sensors are often employed to handle extreme conditions such as high pressures, corrosive atmospheres, and high temperature processes. Ceramic pressure sensors are an ideal alternative to conventional oil-filled pressure sensors under such circumstances.

Because of their unique construction and ceramic’s chemically inert nature, ceramic pressure sensors can withstand harsh atmospheric conditions without sacrificing performance. Robust, reliable, and washable, they are a durable and cost-effective solution to a variety of demanding applications.

The following blog post provides an overview of ceramic pressure sensors, outlining the benefits, types available, and applications.

Benefits of Ceramic Pressure Sensors

Ceramic pressure sensors offer several benefits, including:

• Greater strength and durability. Compared to their stainless steel counterparts, sensing diaphragms made of ceramic are 10x stronger. This quality results in greater durability and longevity. Ceramic’s superior resistance to abrasion further enhances these characteristics.
• Lower cost. Ceramic diaphragms are less expensive to manufacture than stainless steel ones. This quality, coupled with longer service life, can result in significantly lower equipment costs.
• Better corrosion and chemical resistance. Ceramic is chemically inert and corrosion resistant, making it highly compatible with most process materials.
• Smaller environmental risk. Ceramic sensors do not contain oil, reducing their risk of negatively impacting the surrounding environment due to fluid leaks.
• Higher temperature and pressure operating capacities. Ceramic is capable of withstanding greater pressures and temperatures than stainless steel. It also displays a broader range of sensitivity, with the ability to simultaneously measure low pressure while withstanding high overpressure.

The above qualities, among others, make ceramic pressure sensors well-suited for applications with harsh environments. Even when exposed to high pressures, extreme temperatures, corrosive compounds, or high levels of shock and vibration, they provide consistent and reliable performance.

Ceramic pressure sensors have many advantages over traditional stainless steel counterparts. Perhaps most importantly, they are significantly stronger than oil-filled diaphragms. Similarly, they can withstand high operating temperatures and pressures without losing sensitivity at low pressure values. They tolerate relatively high over pressures as well.

Since ceramic sensors do not rely on oil, the diaphragm can be thicker, and it does not carry the risk of a leak that could compromise an entire batch of sensors. Because they are sturdier, ceramic pressure sensors will not deviate from their calibrated setting even after multiple operating cycles, thus minimizing the risk of sensor drift. All these features make ceramic pressure sensors ideal for a large number of industrial applications, particularly if accuracy, dynamic range, and corrosion resistance are critical requirements.

Types of Ceramic Pressure Sensors

Ceramic pressure sensors are available in a wide range of designs, each suited for use in particular applications. Some of the most common ceramic pressure sensor variations include:

Flush Mount vs. Monolithic Sensors

The key difference between flush mount and monolithic ceramic pressure sensors lies in the surface design. While flush mount sensors provide a flat surface for exposure to the pressure media, monolithic sensors feature an indentation in the exposed side of the sensors. As flush mount sensors maintain a fixed reference, they are generally used for applications that require absolute or sealed gauge sensing.

Piezoresistive vs. Capacitive Sensors

Ceramic pressure sensors employ either piezoresistive or capacitive means to measure pressure. Piezoresistive sensors measure the changes in electrical current in direct correlation to changes in pressure on the diaphragm. Capacitive sensors measure pressure displacement by analyzing the difference in electrical frequency between two sensors. The latter type is preferable for applications that require the measurement of low-pressure values under high overpressure conditions.

Amplified vs. Unamplified Sensors

Pressure sensors come with several amplification options—including ratiometric, non-radiometric, current loop, and I2C—each of which can be calibrated as needed. For users who wish to perform their own amplification and calibration, unamplified ceramic sensors are also available.

Ratiometric vs. Non-Ratiometric Sensors

Ratiometric sensors take into account the power supply when converting sensor output, allowing for more accurate measurement without the interference of power supply variation. Non-ratiometric sensors are used when the measurements are against an absolute reference and not affected by fluctuation of the power source.

When to Use Ceramic Pressure Sensors

Ceramic pressure sensors are suited to a wide variety of industries. In the automotive industry, for example, they are often used to measure oil levels. Within the transportation industry, they are used to maintain hydraulic systems (which benefit from greater water resistance) and control emissions (where greater resistance to heat and corrosion may be necessary). They are also used to measure the flow rate of the working fluid in water reservoirs, wastewater treatment plants, and other chemical processing plants.

Due to their superior resistance to corrosion, high pressures, and extreme temperatures, ceramic pressure sensors find use in a variety of industrial applications with harsh environmental and operating conditions. Typical industries that employ these devices include:

• Automotive instrumentation
• Chemical
• Food and beverage 
• Heavy manufacturing
• HVAC
• Oil and gas
• Water and wastewater treatment  

The high strength of ceramic sensors makes them ideally suited for applications that feature a large number of pressure cycles. Because of ceramic’s chemically non-reactive nature, they can be used in HVAC systems to measure refrigerant levels and for flow measurement in the oil and gas industry. They are also inert enough for use in the food and beverage industry to monitor ingredient flow.

Microelectromechanical Systems: Tiny Tech With Major Impact

Microelectromechanical systems, or MEMS, are generally comprised of components less than 100 micrometers in size, and a standard MEMS device typically measures between 20 micrometers and 1 millimeter.

Scientists and industry leaders have been aware of the high potential of micro machines since the 1950s; manufacturing technology simply needed to catch up. For example, today’s MEMS are built with modified semiconductor device fabrication technologies, such as wet etching, molding, plating, dry etching, and electro-discharge machining.

To obtain accurate, precise flow measurements, it’s critical to select the proper MEMS mass flow sensor for the specific application at hand. When choosing a flow sensor, accuracy, sensitivity, and size should all be kept in mind, along with a range of other key factors.

Flow sensors play a crucial role in many different applications and industries, such as chemical and semiconductor manufacturing, medical device manufacturing, and natural gas metering.

Thermal mass flow sensors, in particular, offer numerous advantages, including:

• Small size
• Fast response time
• Low power consumption
• High sensitivity to low flow rates

Operating independently of density, pressure, and viscosity, these devices generally consist of upstream and downstream temperature sensors and a heater located between them.

When selecting a MEMS thermal flow sensor, the following measurement considerations should be kept in mind: mass flow rate vs. volumetric flow rate, mechanical flow channel diameter vs. flow rate, and the nominal operating flow rate of the products.

Mass Flow Rate vs. Volumetric Flow Rate

MEMS flow sensing products typically measure the mass flow rate, which is automatically compensated for changes in temperature and pressure. Mass flow rate always is referenced in relation to the standard condition of a specific temperature and pressure.

The reference pressure is typically 101.325 kPa, or 14.5 PSI; the standard temperature may vary, at 0°, 15°, or 20 °C. The manufacturer will specify the conditions in the user manual. The default reference temperature for current Siargo products, for instance, is 20 °C, which can be customized upon request.

Mechanical Flow Channel Diameter vs. Flow Rate

All flow measurement products are packaged with a flow channel to ensure optimal performance; therefore, it’s critical to select the proper flow channel for the desired flow rate measurement.

It’s generally not recommended that users measure a high flow rate in a small channel or a small flow rate in a large channel. Also, the product’s flow channel should not be connected to a different size system channel. However, if there is no option but to alter the flow channel size, the product’s flow channel size should always be smaller than that of the system channel.

Nominal Operating Flow Rate of the Products

Flow sensors normally have about a 20% margin for the specified full-scale flow rate. However, it’s recommended that users select a full-scale flow rate that falls within the application’s maximum flow rate in order to ensure optimal performance and reliability.

When dealing with low flow rate accuracy, sensor products have a default range of over 100:1, allowing them to meet most applications’ requirements. Most of today’s products do not offer a bidirectional flow rate measurement option, but this can be customized as needed.

For further assistance in picking the right flow sensor for your specific application, and to learn about other key considerations to keep in mind during the selection process, download our free eBook, “MEMS Mass Flow Sensor Selection.”

When selecting a pressure sensor for a specific application, designers must first determine the total system accuracy required, as well as the performance requirements for the lifetime of the product.

Like a bathroom scale that is used day after day, a pressure sensor's output may vary over time. The amount of drift depends on the specification given by the manufacturer. Other factors, such as humidity and operating temperature range, can also affect the accuracy of a pressure sensor, regardless of which type of sensor you purchase.

In critical applications requiring optimal accuracy and minimal drift, designers will have to either calibrate or tweak the performance of the pressure sensor to meet the system accuracy requirements. Furthermore, some systems often require recalibration or resetting to zero to ensure optimal reliability after extended use. Back to our example, a good analogy is a mechanical scale, in which the zero point will drift over time and the user must adjust the zero point to maintain accurate weight measurements.

A bill of materials, though intended to estimate project costs for production volumes, can actually distract from one of the most expensive aspects of a project — the labor required to inspect, install, and test different components. By focusing on the price tag of individual components themselves, manufacturers often overlook the additional costs of board space, sourcing from multiple distributors, calibration labor, stocking locations, and multiple purchase orders.

Alternatively, sourcing one complete sensor solution from one provider can alleviate all of these pain points while incurring lower service costs down the road. In particular, customers without explicit sensor design/calibration expertise can greatly benefit from an all-in-one solution, as it allows them to reduce both labor and overall bill of materials costs.

Partnering with the factories we represent,  Servoflo supports customers anywhere along the price/performance continuum from the most basic components to modified output sensors to completely customizable turnkey sensor solutions across a wide range of industries. Depending on the factory/partner, it could be possible to add a display unit, Wi-Fi, or Bluetooth capabilities.  Or,  adding flex to a sensor, creating packaging enclosures and custom flow paths, or integrating multiple parameters into a single sensor.  It is worth the time and effort to ask:  Who can best provide the required features:  factory or customer?

Throughout our nearly 30 years of experience providing efficient, reliable sensor related services, we’ve handled a diverse range of projects. Below are some examples of our past work and tailored solutions.

• Creating a pressure gauge with display and enclosure
• Integrating a pressure sensor and electronics in a hybrid circuit design for better protection in high-temperature and high-humidity environments
• Eliminating installation assembly and testing by adding a flex cable to a standard board level sensor
• Customizing sensor calibration and output to meet exact customer specifications
• Designing a custom flow path in a mass flow sensor for medical equipment
• Designing custom electronics to create pressure switches, mass flow switches, and other environmental sensors

As with all of our application-specific work, these solutions helped customers simplify their bill of materials and reduce downstream maintenance costs for maximum lifetime cost efficiency.
