General Purpose Silicon Piezoresistive Pressure Sensor

 

Silicon Piezoresistive Pressure Sensor is suitable for all: Water pressure, air pressure, oil pressure, hydraulic pressure.

General Purpose Silicon Piezoresistive Pressure Sensor is composed of diffused silicon sensor and signal module. It uses the piezoresistive effect of semiconductor silicon material to realize the conversion of pressure and electrical signals. Convert the sensor signal to a standard current or voltage signal output, which can be directly connected to the computer, control instrument, display instrument, etc.

 

 Features of General Purpose Silicon Piezoresistive Pressure Sensor
