Product overview
PC91 Monocrystalline Silicon Pressure Sensor adopts the
imported MEMS monocrystalline silicon pressure die, achieves
international leading overpressure performance and ensures the
excellent stability of signal. It is assembled in all-welded seal
structure and filled with silicon oil in high vacuum. Measuring
diaphragm of different materials isolates measured medium and
pressure die, meanwhile, the sensor performs long-term reliable
measurement of differential pressure signals of various strong
corrosive medium.
PC91 Monocrystalline Silicon Pressure Sensor allows
may
cause
measured pressure to act directly on the diaphragm of sensor.
Then the diaphragm produces a microdisplacement proportional
to the pressure, which can be detected with the integrated
electronic circuit and be converted to output a standard
measurement signal of the corresponding pressure.
