PM410 Corrosion Resistant Pressure Sensors
PM410 Corrosion Resistant Pressure Sensors, a low-cost, high-precision, high-reliability, practical product. Especially recommended for corrosive media.
Corrosion Resistant Pressure Sensors working principle
The corrosion-resistant ceramic pressure sensor has no liquid transfer, and the pressure acts directly on the front of the ceramic diaphragm, causing a slight deformation of the diaphragm. The thick film resistor is printed on the back of the ceramic diaphragm and connected to a Wheatstone bridge (closed bridge). Due to the piezoresistive effect of the varistor, the bridge produces a highly linear voltage signal proportional to the pressure and excitation voltage. The standard signal is calibrated to 2.0/3.0/3.3mV/V depending on the pressure range and is compatible with strain gauge sensors. Through laser calibration, the sensor has high temperature stability and time stability, and the sensor comes with temperature compensation of 0~70 °C.
The high-reliability amplifier circuit and precise temperature compensation convert the measured medium pressure into standard electrical signals such as 4~20mADC or 1~5VDC.
