Microsensorcorp MPM3801 Digital Output Pressure Sensor

Microsensorcorp MPM3801 Digital Output Pressure Sensor is the OEM piezoresistive pressure sensor with 316L stainless steel corrugated diaphragm and isolated oil-filling construction. The sensing package utilizes silicone oil to transfer pressure from the 316L stainless steel diaphragm to the sensing die.

The pressure is transformed into an analog electric signal. By customized integrated circuit for temperature compensation and non-linearity correction, it outputs pressure data and temperature data conforming to I2C interface protocol or SPI interface protocol.

With digital normalized output and low power consumption, it is convenient to connect to various devices and has strong applicability. It is widely used for various liquid pressure measurements which is compatible with stainless steel and Viton.
