Silicon Oil Filled High Stable Sensor Monocrystalline Silicon Pressure Sensor PC91

Product Description

Product Description

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.

Features
Imported MEMS monocrystalline silicon pressure die
With overload protection
316L stainless steel all welded integrated structure
Gauge pressure type applicable to negative pressure measurement
Suitable for a variety of threads and shells

Applications and industries
Provide OEM for industrial transmitter manufacturers

Product overview 
The PC91B monocrystalline silicon pressure sensor adopts imported MEMS monocrystalline silicon pressure dies, achieving internationally leading overpressure performance and ensuring excellent signal stability. It is assembled with a fully welded sealed structure and filled with silicone oil under high vacuum. Different materials of measurement diaphragms not only isolate the measured medium from the pressure die but also enable the sensor to reliably measure the pressure difference signals of various strongly corrosive media over the long term.

In the PC91B monocrystalline silicon pressure sensor, the measured pressure directly acts on the sensor's diaphragm, causing a micro-displacement proportional to the pressure. Integrated electronic circuits detect this change and convert it into a corresponding standard measurement signal for pressure.

Features
Adopt imported MEMS monocrystalline silicon pressure dies
With overpressure protection
316L stainless steel fully welded integral structure
Gauge pressure type can be used for negative pressure measurement
Suitable for various threaded housings

Applications
Provide OEM parts for industrial transmitter manufacturers.
