Monocrystalline Silicon Pressure Sensor PC91
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 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.
