Overview
PC90 Monocrystalline Silicon Differential Pressure Sensor is a kind of differential pressure sensor designed with overpressure protection function. The differential pressure sensitive core element adopts high performance piezoresistive silicon chip, which is assembled in all-welded seal structure and filled with silicon oil in high vacuum. Diaphragm of different materials isolates measuring medium and differential pressure die, meanwhile, the sensor performs long-term reliable measurement of differential pressure signals of various strong corrosive media. Differential pressure sensor converts the measured differential pressure signal into millivolt voltage signal proportional to its linearity by external constant current or constant voltage excitation.
