Learn the Difference: Rated Pressure, Overpressure & Burst Pressure

Posted by Seta Davidian on Nov 12, 2021 12:45:18 PM

In many applications and industries, it is not uncommon to come across the risk of excessive pressure, or overpressure, within the pneumatic or hydraulic network of equipment, especially in facilities with a high degree of automation. If this phenomenon is not controlled properly, it may cause permanent damage to equipment and production lines which is why pressure sensors are commonly used as some form of protection in several operations such as industrial, medical, bioprocessing, and pharmaceutical.

ESCP-MIS1-headerNevertheless, pressure transducers are not always able to handle extreme levels of pressure. In order to survive extreme pressures, engineers and designers have defined pressure ratings that can describe the conditions a pressure component can withstand without affecting its operational performance. These are divided into:

            • rated pressure
            • overpressure
            • burst pressure

The maximum pressure that the manufacturer assigns as the desired pressure at which a device will function properly is normally outlined as rated pressure. An overpressure value is a condition where the pressure transducer can withstand excessive pressure without affecting performance or compromising subsequent measurements. Often overpressure is mistaken for burst pressure, which is defined as the maximum pressure that can be applied without physically damaging the body of the sensing component.

For example, if a pressure sensor has 2 bar rated pressure, 5x overpressure, and 10x burst pressure, this means that the sensor can measure pressures up to 2 bar, it can withstand overpressures up to 10 bar without being damaged, and if the pressure reaches 20 bar the sensor sealing will burst. From 10 to 20 bar, the sensor does not burst but it is damaged and will not operate as expected.

What can cause overpressure?

Different factors can trigger overpressure, including unintentionally increased heat, uplift, a faulty pressure regulator, process synchronization, or an amalgamation of all these factors.  These causes are common in industrial applications where there are solenoids, centrifugal pumps, regulators and valves.

How capacitive sensors can prevent catastrophic failures due to overpressure

Due to their design and measurement principle, MEMS capacitive pressure sensors can handle up to 100x overpressure, making them the only available sensor technology in the market that can withstand high overpressure.

The overpressure tolerance along with the excellent accuracy and total error band specification make capacitive sensors ideal for any application that uses pumps or valves, especially in automation equipment, where overpressure is frequently experienced. 

Before selecting a sensor, the maximum pressure value needed for the application should be taken into consideration. Understanding the advantages of each technology, the dynamics of their system, the limits of the sensor, and the various ways it can be applied are important to increase productivity and lower maintenance costs.

In the following figure, you can see an application example of the overpressure performance of a 10 bar absolute calibrated sensor from ES Systems. The sensor's maximum expected operating pressure (MEOP) is 10 bar. The sensor is measured at a reference pressure of 9.3 bar absolute and then pressurized at the following pressure steps as seen in the graph below.


As predicted, the sensor returns to nominal performance even with 100x overpressure is applied for a long period of time. 

Pressure sensors with high overpressure tolerance

ESCP_BMS1-header-newES Systems has developed high-end pressure sensors with cutting-edge MEMS capacitive technology and overpressure tolerance. Because of their revolutionary design, they can withstand up to 100X the rated pressure with no plastic deformation and can be replicated in any harsh environmental condition. Furthermore, the total error band is unsurpassed in the pressure sensor market (see our post about accuracy).

Pressure Sensors for Medical Ventilators

Posted by Seta Davidian on Jul 8, 2021 4:04:35 PM

Medical ventilators supply air or other gaseous mixtures to patients through the use of pressure. These devices are used when patients require assistance breathing or are entirely unable to breathe on their own. One vital component that these systems use to function is a pressure sensor.

In this blog post, we'll review how medical ventilators work and the role that pressure sensors play in the functionality of these devices.


How Does a Ventilator Work & When Are They Used?

Hospitals often use medical ventilators as life support devices for patients who are either unable to breathe on their own or experience difficulty breathing. There are both invasive and non-invasive ventilators available. While noninvasive ventilators use an airtight external mask, invasive ventilators involve inserting internal tubes via tracheostomies or intubation.

Medical ventilators are normally used as a temporary measure to assist with breathing for a limited time, such as when a patient is undergoing surgery. Anesthesia may slow patients' breathing, warranting the use of a ventilator throughout a surgical procedure. In some cases, patients with serious medical conditions that affect their breathing may require ventilation during the recovery process, usually while receiving treatment in a hospital's critical care unit (CCU) or intensive care unit (ICU).

Other conditions that may require the use of a ventilator include acute respiratory distress syndrome (ARDS), pneumonia and other respiratory infections, lung diseases, brain injury, drug overdoses, or strokes. 


Where Are Pressure Sensors Used on a Ventilator?

Pressure sensors are integral to medical ventilators. Depending on the type of system, medical industry pressure sensors are used in several places on a ventilator, including:

  • Measurement of the pressure between the regulator and filter from the starting oxygen and air inputs
  • Measurement of pressure when the patient inhales, along with the pressure of the gases leading to external humidifiers
  • Measurement of pressure when patients exhale into medical ventilators
  • Measurement of barometric pressure to offset changes in elevation

Depending on the role of a pressure sensor in a ventilator, several sensor solutions are available for different applications. These include filter monitoring, airflow control, O2 flow control, O2 source pressure, CO2 level, and humidifier solutions.

Barometric Sensors 101

Posted by Seta Davidian on May 24, 2021 1:14:59 PM

What is a Barometric Pressure Sensor?

SOP30DA barometric pressure sensor is a new type of barometer that measures atmospheric pressure. They are commonly used for weather measurement, altitude compensation, dive watches, altimeters, underwater equipment, and much more. At Servoflo, we offer a wide range of standard and compact barometric pressure sensors suitable for a wide range of applications.


How Does a Barometric Pressure Sensor Work

In older sensors, barometers used liquids to measure atmospheric pressure. One of the oldest types of barometers used mercury, which would raise or lower within a column in response to pressure changes. As technology advanced, the aneroid barometer was invented. This type of barometric pressure sensor utilizes an aneroid cell that expands or contracts when the atmospheric pressure changes. This movement causes the levers to amplify, which results in display pointers indicating the pressure reading on the front display. 

Many of today’s modern barometers utilize microelectromechanical system (MEMS) technology, making them capable of measuring pressure in a more compact and flexible structure. This allows them to be used in smaller applications such as mobile devices and watches. A MEMS barometric pressure sensor detects atmospheric pressure based on how it affects its diaphragm. The more the diaphragm deforms, the higher the pressure.

Applications For Barometric Pressure Sensors

Barometric pressure sensors are used in a wide variety of applications including:

  • Predicting weather. The most common application for barometric pressure sensors is monitoring and predicting weather conditions. Even tablets and mobile devices come equipped with barometric pressure sensors that give users immediate insight into local weather conditions.
  • Altitude compensation. Higher altitudes can affect the measurement of various environmental parameters and overall performance of various equipment such as medical devices, consumer equipment and much more. Barometric pressure sensors can provide the altitude compensation needed for other types of sensors and equipment to function properly.
  • Navigation. Barometric pressure sensors are utilized for navigation purposes using the altimeter function, which enables accurate vertical positioning. For example, it helps when you are climbing between floors or up a mountain.
  • Devices that monitor physical activity. They are used in devices that monitor physical activities in wearable devices. This helps the wearer more accurately track activity via air turbulence instead of just steps.
  • Drones. As more and more applications adopt drone technology, barometric pressure sensors become very important in measuring precise altitude and air pressure on these devices.

Pressure Sensors for Critical Environments

Posted by Seta Davidian on May 11, 2021 1:37:54 PM

Pressure Sensors for Critical Environments

For many decades, Servoflo has been helping companies meet their pressure sensing measurement needs for a variety of applications, including those in critical environments. Our pressure sensors range from 0.15 psi to 9000 psi (600 bar) in compensated, uncompensated, amplified, and unamplified modules. With our broad lineup of sensors for critical environments, we can help you find the perfect sensor.

Managing Critical Environments

When you need to maintain tight control over critical spaces to protect patients, personnel, and assets, managing room pressure and controlling the environment is crucial. Areas such as cleanrooms, laboratory equipment, negative-pressure ambulances, and hospital isolation rooms all need environment controls and a way to warn personnel of potential problems or automatically trigger adjustments.


cleanroom pressure sensors

Sensors can provide early warning of changes that can impact performance – such as differential pressure between a cleanroom and an outside environment. 

Maintaining a specified differential pressure between the cleanroom and outside environments, such as an isolation layer, keeps dust and contamination out. Cleanroom sensors can be used to provide continuous environmental pressure monitoring. When a change is detected, it can signal control units to automatically start fans to boost the cleanroom. 

Laboratory Equipment

biological safety cabinet pressure sensorsLaboratory equipment such as biological safety cabinets and fume hoods have strict safety requirements to prevent noxious fumes or contagions from impacting lab personnel. Pressure sensors can provide feedback as HEPA filters load to increase blower speed to maintain safety.


Pressure sensors can provide an early warning for changing conditions that can impact performance and safety in negative-pressure ambulances. This is especially important for ambulances used to help safely treat and transport patients with potentially infectious diseases. The negative pressure filters the air so that only outside air can flow to the inside.

Inside air is passed through a biosafety exhaust purification system to minimize cross-infection of medical staff during treatment and transport. Sensors for ambulances monitor conditions to provide a safer environment.

Isolation Rooms

Hospital isolation rooms require special air handling equipment which can provide either positive or negative pressure. Negative pressure keeps air from flowing out of the isolation room while positive pressure prevents the transmission from the outside environment.

In either case, isolation room sensors ensure the pressure is consistent to keep patients and medical professionals safe.

How Does a Humidity Sensor Work?

Posted by Seta Davidian on Mar 2, 2021 1:52:43 PM

What Is a Humidity Sensor?

humidity-group-newHumidity refers to the amount of water vapor present in the surrounding air. Humidity sensors are devices that measure moisture and air temperature in an environment and convert the data into a corresponding electrical signal. Modern humidity sensors are highly adaptable and come in many shapes and sizes, from miniature sensors installed in cell phones, to larger, industrial-grade systems. 


How Do Humidity Sensors Work?

Typically, humidity sensors contain a humidity sensing element and a thermistor, which is used to measure temperature. There are three main types of humidity sensors, each of which monitors small changes in the atmosphere to calculate humidity. These types include:

  • Capacitive. Capacitive humidity sensors are linear and measure relative humidity from 0% humidity to 100% humidity. They do this by placing a small metal oxide strip between two electrodes. As the level of humidity changes, the oxide's electrical capacity changes along with it. 
  • Resistive. Resistive humidity sensors measure humidity through the use of ionized salts between two electrodes. The ions in the salts measure the electrical impedance of atoms. As humidity levels change, so does the resistance of the electrodes.
  • Thermal. A thermal sensor utilizes a dual sensor system to measure humidity. One thermal sensor is housed in a layer of dry nitrogen; the other freely measures ambient air. The resulting difference between the two measurements represents the level of moisture in the air. 

Humidity Sensor Applications

Humidity sensors are used across several industries to protect equipment and ensure safe and comfortable environments. Common applications include:


  • Meteorology. Meteorological departments rely on humidity sensors to gauge accurate weather conditions in their respective areas. 
  • Medical. Many lifesaving medical devices rely on humidity sensors to regulate moisture. Ventilators, incubators, sterilization equipment, and more require careful moisture regulation to ensure safe and sterile function.
  • Automotive. Vehicles use humidity sensors for purposes such as air intake in the engine and climate control inside the vehicle.
  • HVAC. Humidity sensors are critical to climate control functions found in residential, commercial, and industrial HVAC systems.  
  • Manufacturing. Manufacturing equipment for food processing, textiles, paper, and more require humidity sensors to control the amount of moisture in the air and ensure the quality of their finished products.

Aside from those listed above, other industries that rely on humidity sensors include pharmaceutical, agriculture, electronics, and more.


Humidity Sensors from Servoflo
