There are two types of pressure sensors used for negative pressure or vacuum pressure applications: gauge sensors and absolute pressure sensors. The reference pressure is the differentiating factor between these 2 types of sensors. The diagram below illustrates how the different methodologies work.
In applications that rely on the principle of a vacuum, it is important to effectively measure negative pressure (also known as vacuum pressure). There are two basic ways to do so:
Measure the amount of pressure below local atmospheric pressure [typically 14.7 pounds/ square inch absolute (PSIA)]
Measure how much pressure is above absolute zero vacuum (0 PSIA)
Both methods of measurement utilize the same scale and pressure point. However, these two measurements will yield differing results over time because one measurement's reference point is a fixed quantity (absolute zero vacuum), whereas the other relies upon a variable amount (atmospheric air pressure, which can fluctuate).
In the case of a gauge sensor, either a single port or dual port model can be used. In the case of a dual port gauge sensor, the "lower pressure" port measures the negative or vacuum pressure.
By accessing the "lower pressure" port, the user is mimicking applying positive pressure to the higher pressure port as in pressure range.
The advantage of using a gauge sensor is if the user wants to measure a vacuum smaller than the full vacuum range 14.7 psi, such as -3 psi, using a lower range focusing on the negative pressure range is more appropriate. This way, by using a smaller full-scale range pressure sensor, the user captures the full-range of the vacuum pressure measurements, thus obtaining more resolution and more design flexibility. For a single port gauge sensor, the single port is vented to the atmosphere.
For example, if a user is trying to measure the inhalation pressure in a respiratory application, the pressure range would be no more than 0.6 psi. If an absolute pressure sensor is used, only 4% of the pressure range would be used, hence wasting 96% of the sensor's calibrated range. By using a gauge sensor such as the AL4 Series, the user can capitalize on higher resolution and measure smaller negative pressure ranges.
Measuring Pressure Below Local Atmospheric Pressure Sources
Vacuum pressure is typically measured in terms of psi or pounds per square inch vacuum (PSIV). This measurement is generally relative to the surrounding atmospheric pressure. Vacuum pressure transducers can convert the inner negative pressure contained by an application into an electrical signal, and from there into a precise measurement.
At 0 PSIV—which is the same as typical atmospheric pressure, or 14.7 PSIA—the electrical output of a vacuum pressure transducer is 0 VDC. At full-scale, vacuum (14.7 PSIV or 0 PSIA), the output generally increased to about 5 VDC. A vacuum pressure transducer's output in volts increases proportionally to the increase in vacuum or negative pressure. On the other hand, an absolute pressure transducer emits increased positive voltage in proportion to decreasing vacuum.
Measuring How Much Pressure is Above Absolute Zero Vacuum Sources
The scale for absolute pressure begins at the high vacuum point of 0 PSIA. Unlike measurements that rely on atmospheric pressure as their main reference point, this methodology allows for more consistent readings.
An absolute pressure transducer features an electrical output of 0 VDC at 0 PSIA and increases to 5 VDC when it reaches full-scale pressure (14.7 PSIA). This output is expressed in positive voltage.
Pressure Sensors that Measure Negative Pressure
Vacuum pressure transducers and absolute pressure transducers measure the same thing using different points of reference. They are both crucial components for use in applications that require accurate and reliable negative pressure measurements for proper functionality and optimal performance.
When attempting to measure negative air pressure, it's important to use the proper equipment and to have that equipment calibrated to yield correct readings. Even small discrepancies between measurement and actual vacuum level could lead to performance issues.
Examples of classic applications where negative pressure measurements are needed include negative wound pressure therapy, breathing applications, pump control/performance monitoring, HVAC applications such as filter monitoring, and pressurized rooms such as cleanrooms and isolation rooms. One pressure sensor series which works well for these applications is the AP/AG Series from Fujikura.

Various technologies are used to make pressure sensors. 2 of the most common include piezoresistive and capacitive pressure sensors. Both can be used for gauge, differential, or absolute pressure measurement. While piezoresistive is found in low-cost sensors, there are situations where a capacitive pressure sensor is better suited for the application.
In capacitive pressure sensors, the electrical capacitance changes with pressure. In simplified terms, this change in capacitance is measured and converted to a pressure measurement. This capacitive element technique creates a pressure sensor with key advantages, including:
Robustness: Capacitive pressure sensors can easily withstand high proof pressures and overpressure.
Temperature performance: These sensors can operate over a wider temperature range than traditional piezoresistive pressure sensors.
Power consumption: Capacitive pressure sensors use low power because no bias is required to operate the sensor. This feature makes the sensors suitable for IIOT products where power use is critical. The sensors can be operated in extremely low power modes until activated when needed.
Accuracy: Low hysteresis, high repeatability and low sensitivity to temperature changes allow for highly accurate sensors.
Long-term stability: Minimal drift gives users superior long-term stability over other pressure sensors.
Newer packaging styles: Capacitive sensors have become much smaller compared to older generations which resembled a brick.
Because the production and calibration costs of capacitive sensors are higher, it is not expected to act as a replacement for lower-cost piezoresistive pressure sensors. Instead, these newer generation capacitive sensors open up opportunities for pressure measurement than cannot be done with piezoresistive pressure sensors. Some sample applications include:
Production Equipment: Automated pumps and valves need to be monitored for pressure. A capacitive sensor has the safety to be exposed to harsher environments.
Industrial Filter Monitoring: Differential pressure measurement is required to monitor filter clogging in industrial equipment. The capacitive sensor offers excellent overpressure tolerance (typically 100 times) and has a minimum in-line pressure drop requirement.
Powerless Pressure Monitoring System: Due to its nature, a capacitive pressure sensor does not require DC bias for its operation, minimizing power requirements, and allowing the user to set up remote wireless monitoring. Wireless level tank monitoring can be done by creating a sensor network with data sent to the cloud. The excellent overpressure tolerance and high accuracy combined with the low power requirement make the capacitive pressure sensors a unique solution to solving difficult pressure measurement situations.

How do you convert an air velocity measurement to a volumetric flow rate? It is important to understand the various formulas and technical definitions to prevent errors in calculation.
Volumetric flow rate is the volume of fluid that passes per unit of time.
Flow meter technologies such asdifferential pressure, magnetic, thermal, turbine, ultrasonic, and vortex all measure flow rate as a function of fluid velocity. Please refer to the respective flow meter datasheet for detailed information and specifications.
You can calculate the volumetric flow rate by using the equation shown below:
For example, if a gas had a velocity (V) 15 m/s and was traveling through a pipe of 20mm inner diameter then the volumetric Flow Rate (Q) would be 0.004712 m3/s which is equal to 282.74 l/min.
Converting velocity to mass flow rate
Similarly, the volumetric flow rate can be converted to the mass flow rate if the density of the gas measured is known.
ṁ is the mass flow rate in kg/s
ρ is the density in kg/m3
From the two equations above it can be derived that:
Mass Flow Rate (ṁ) = V × A × ρ
Using the same example as above, if the density was 998 kg/m3then the volumetric flow rate of 282.74 l/min would be equivalent to a mass flow rate of 4.703 kg/s.
Velocity profiles – Laminar & turbulent flow
Laminar flowis described as fluid particles following smooth paths in layers, with each layer flowing smoothly past the adjacent layers with little to no mixing in fluid dynamics. The fluid continues to flow without lateral mixing at low velocities, and neighboring layers float past each other like playing cards.
Turbulence, also known asturbulent flow, is a fluid motion characterized by chaotic variations in pressure and flow rate in fluid mechanics.
Laminar flow can be, in general, achieved by providing a 20x the internal diameter of the tube used straight tube length in upstream and downstream flow. For example, if a 25mm ID tube is used, if you connect a 50cm straight tube upstream and downstream of the flow meter, you can expect a laminar flow.
In most applications, turbulent flow is present in the application. This increases the flow noise observed by the flow meter.
Volumetric & mass flow rate units
Volumetric flow rate can be expressed in a variety of units with the most common being m3/s, m3/min, m3/h in metric units and the respective imperial units.Volumetric flow rateis also typically expressed in l/s, l/min, l/h.
Mass flow rate is usually referenced in kg/s, kg/min, kg/h in metric units and in lb/s, lb/min, lb/h in the respective imperial units.Mass flow ratecan be also expressed in l/s, l/min, l/h but with one condition.
Due to the fact that for mass flow measurement the gas density must be taken into account, when using l/min unit for mass flow, the temperature and pressure reference conditions must be noted.
There are two common reference conditions for mass flow measurements. These are:
Normal, expressed at 0oC temperature and 1013 mbar pressure and denoted as ln/s, ln/min, ln/h
Standard, expressed at 20oC temperature and 1013 mbar pressure and denoted as ls/s, ls/min, ls/h
Converting mass flow from reference to ambient conditions can be achieved using the following formula:
Pressure is in mbar
Temperature is in Kelvin
Converting differential pressure to flow velocity
Before going intohow to convert differential pressure to flow velocity, it is important to note the definitions ofstatic,dynamic,andtotal pressure.
The constant physical force exerted on or against an object by something (such as air) in contact with it is known aspressure.
What’s static pressure?
The pressure you get when the fluid isn’t flowing or when you’re moving with the fluid is called static pressure. While now moving, air would press against you equally in all directions. Because of the conservation law, static pressure decreases as the speed increases.
What’s total pressure?
The pressure a fluid exerts when it comes to a full stop is known as absolute (or total) pressure. When you face the wind and the air collides with your body, total pressure acts on you.
What’s dynamic pressure?
Dynamic pressure is the pressure exerted by a fluid as it travels. It refers to the difference between total and static pressure.
In order tomeasure flowvia differential pressure, a deliberate obstacle has to be introduced in the flow line in order to impose the increaseddifferential pressure measurement. The obstacle can be anything, from an orifice to a simple narrowing of the tube.
Using Bernoulli’s principle, you can correlate flow velocity with differential pressure using the following formula:

In many applications and industries, it is not uncommon to come across the risk ofexcessive 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 asindustrial,medical, bioprocessing, and pharmaceutical.
Nevertheless, 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:
The maximum pressure that the manufacturer assigns as the desired pressure at which a device will function properly is normally outlined asrated pressure. Anoverpressurevalue is a condition where the pressure transducer can withstand excessive pressure without affecting performance or compromising subsequent measurements. Often overpressure is mistaken forburst 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
ES 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).
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.

A 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.
