OEM Piezoresistive Pressure Sensors Transducers MPM Series

Micro Sensor has been manufacturing piezo-resistive pressure sensors (isolation measuring cells) since the1990s. Now we offera series of pressure sensors with digitalor analog output signal (I²C, SPI, mV), in different diameter (19mm, 17mm, 15mm, 12.6mm), made of differentmaterial(SS316L, Titanium, Hastelloy and Tantalum).

MPM3801 Digital Pressure Sensor

MPM3801 measures both pressure and temperature value, and communicatesby I²Cor SPI interface protocol, using an integrated circuit for temperature compensation and non-linearity correction.
