PC90M Multivariable Differential Pressure Sensor
The PC90M multivariable differential pressure sensor is a differential pressure sensor with overload pressure protection. The differential pressure-sensitive core uses an imported high-stability single-crystal silicon differential chip from Germany. It is packaged using a fully welded sealed structure and is filled with silicone oil under high vacuum. Measurement diaphragms of different materials not only isolate the measured medium and the differential pressure chip but also enable the sensor to reliably measure the pressure difference signal of various strongly corrosive media over a long period. The differential pressure sensor can convert the measured pressure difference signal into a millivolt signal linearly proportional to it through external excitation.
