Piezoresistive pressure sensor is a silicon oil-diffused type pressure sensing element. It is fully stainless steel constructed with ranging from 0.2 bar to 1000 bar. With long-term stability, constant voltage, and current supply, the pressure sensor is suitable for fluid pressure measurements, such as for air, water, gas, or oil.
Piezoresistive strain gauges are among the most common types of pressure sensors. They use the change in electrical resistance of a material when stretched to measure the pressure.
