Pressure sensors – our core expertise, your advantages

Pressure sensors can be found in many different industries and applications and enable precise measurements and monitoring of pressure conditions. They convert the physical quantity of pressure into an electrical signal. There are different types of pressure sensors, which differ in the way they measure pressure. The exact choice of sensor may depend on the specific application family and the required accuracy. At All Sensors you will find different types of pressure sensors that can also be customised to your individual requirements. What they all have in common is their high quality, reliability and reproducibility.

Our selection of pressure sensors

  • Absolute pressure sensor: Absolute pressure sensors are used in industrial plants to measure and monitor the pressure inside a system. Absolute pressure sensors must be used in environments where the ambient pressure has no influence on the pressure in the system. Closed compressed air systems are an example of such an environment. Absolute pressure sensors are used to measure pressure in gas cylinders and pneumatic systems (compressors).
  • Relative pressure sensor: Relative pressure sensors are instruments that measure the pressure of a gas or liquid in relation to atmospheric pressure. They are the ideal solution for monitoring and controlling pressure in industrial processes, including oil and gas, chemical, power generation and water treatment.
  • Differential pressure sensor: A differential pressure sensor is an instrument used to measure the difference in pressure between two separate points in a system. These sensors are capable of accurately detecting minute differences in pressure and converting them into an electrical signal that can then be interpreted by other devices or systems.

The different pressure measurement techniques

In order to select the right pressure sensor, it is not only important to choose the right type, but also the right measurement technology. Of course, you will find all options in our range.

Piezoresistive pressure sensors

Piezoresistive pressure sensors are one of the most commonly used types of pressure sensors. The reason for this is their relatively simple design and the good linearity between the applied force (pressure) and the generated output signal. A piezoresistive pressure sensor comprises a silicon-based Wheatstone bridge as the measuring element. When pressure is applied, the element expands minimally and changes its electrical resistance. This is known as the piezoresistive effect.

Piezoelectric pressure sensors

Piezoelectric pressure sensors are based on the use of a crystal, such as quartz. When pressure is applied, it generates an easily measurable, proportional electrical charge. This process is known as the piezoelectric effect. Piezoelectric pressure sensors are particularly suitable for measuring dynamic pressures, low pressure fluctuations at high static pressures and quasi-static pressures when measuring very high or very low temperatures.

Capacitive pressure sensors

A capacitive pressure sensor works in a fundamentally different way to the other types of pressure sensor. They are, in fact, plate capacitors. They consist of a membrane and a substrate that act as a hermetically sealed anode and cathode. Pressure on the membrane reduces the distance between them, allowing electrons to pass through. This results in a measurable change in capacitance that corresponds directly to the change in pressure.

Digital pressure sensor vs. analogue pressure sensor

In essence, a digital pressure sensor is a device that measures the physical quantity of pressure and then converts this measurement into a digital format. The process involves transforming analogue physical data into discrete digital values, frequently in the form of binary code (0 and 1).

In contrast, an analogue pressure sensor is designed to directly measure the physical quantity in question, subsequently providing an output signal that is proportional to the measured quantity. Therefore analogue sensors generate continuous and analogue output signals that accurately represent the value of the measured parameter without any discretisation or digital conversion. the advantage of digital pressure sensors is, that they can easily be adjusted and altered to the needs of a taks or customers specifications.
