Monocrystalline silicon differential pressure sensor manufacturer

From: Issued date 2020.08.11 Back

PC90D monocrystalline silicon differential pressure sensor is a differential pressure sensor with overload pressure protection function. The differential pressure sensitive core adopts imported high-stability monocrystalline silicon differential pressure chip, which is packaged with a fully welded and sealed structure, and is filled under high vacuum. Silicon oil and measuring diaphragms of different materials can isolate the measured medium from the differential pressure chip, and at the same time enable the sensor to perform long-term and reliable measurement of the differential pressure signals of various highly corrosive media. The differential pressure sensor can convert the measured differential pressure signal into a millivolt signal linearly proportional to it through external excitation.
