Overview
PC33 High-Stability Pressure Sensor adopts monocrystalline
silicon sensor die with advanced MEMS technology, 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. Diaphragm of
different materials isolates measuring medium and pressure die,
meanwhile, the sensor performs long-term reliable measurement
of differential pressure signals of various strong corrosive media.
PC33 High-Stability Pressure Sensor allows measured pressure
to act directly on the diaphragm of sensor. Then the diaphragm
produces a micro displacement 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.
