Differential Pressure Sensor with Dual Sensor PC90E
Product Overview
The PC90E differential pressure sensor with dual sensor is a type of differential pressure sensor with a large number of programs. The differential pressure sensitive core adopts a high-performance silicon piezoresistive differential pressure chip, which is assembled using a fully welded sealing structure and filled with silicone oil under high vacuum. Different materials of measuring membranes not only isolate the measured medium from the differential pressure chip, but also enable the sensor to reliably measure the differential pressure signals of various highly corrosive media for a long time. The differential pressure sensor converts the measured differential pressure signal into a linearly proportional millivolt voltage signal through external constant current power supply excitation.
