Pressure sensors / pressure measuring cells

Pressure sensors are electronic devices used to measure the pressure of gases or liquids. Pressure sensors are used in many applications such as automotive, aerospace, medical and industrial automation.

There are different types of pressure sensors based on different measurement principles. Some sensors use piezoresistive effects to measure the deformation of a material under pressure. Other sensors use capacitance measurements or magnetic effects to convert pressure changes into electrical signals.

A typical pressure sensor consists of a sensing element that measures pressure and an amplifier or analogue-to-digital converter (ADC) that amplifies and digitises the signal from the sensing element. The output signal from the sensor is converted to an electrical voltage or signal representing the measured pressure.

The accuracy and sensitivity of a pressure sensor depends on several factors such as the size and type of sensing element, the sensitivity of the amplifier, the pressure measurement range and the type of medium being measured. Some pressure sensors have high sensitivity and accuracy, but are susceptible to interference and vibration. Other sensors are more robust and stable, but have lower resolution and sensitivity. The choice of pressure sensor depends on the application and the requirements for accuracy and stability of the measurement.
