Piezoresistive pressure sensor diffusion silicon pressure sensor The piezoresistive sensor has become a commonly used pressure sensor thanks to the widespread use of MEMS manufacturing technologies. These make the sensors relatively inexpensive to produce, assuming they do not need specialized packaging to handle dirty or hostile environments.

Piezoresistor pressure sensor is a sensor made of piezoresistor effect of monocrystalline silicon and integrated circuit technology. When the monocrystalline silicon material is affected by the force, the resistivity changes, through measuring circuit, ratiometric output signal to force change can be obtained.

How to select a suitable pressure sensor or transmitter sometimes is a difficult decision. Here are some tips for you. There are six common types of pressure sensor in our market, it's hard to say which one is the best, however, we can select the most suitable one upon our application and practical condition, we can use below table to analyze their different performances and features.

Industrial pressure sensors also referred to as pressure transducers, pressure transmitters, pressure indicators and pressure switches, normally have a diaphragm type design that uses strain gauges, which are either bonded to or diffused into it, with the strain gauges acting as resistive elements.

Terms of pressure sensor, pressure transducer and pressure transmitter are somewhat interchangeable in the industrial world. Pressure sensors can be described with a 4-20mA output signal and pressure transducers with a millivolt signal.
