MPM490 uses piezo-resistive differential pressure sensor as sensing element. Silicon oil is filled in between die and two diaphragms, when measured differential pressure is added on two deaphragm, the pressure could be transferred onto die through silicon oil. Sensor die connects with amplifier circuit through wires, using semi-conductor's piezo-resistive effect, transforming differential pressure signal into electric signal. The whole product is used for differential pressure measurement of pretroluem, chemi-industry, power station and hydrology, etc.
