Hygienic Pressure Sensor

As a hygienic pressure sensor and transmitter, the MPM280PD1 piezoresistive silicon pressure sensor is designed for the hygienic applications, with the diaphragm OD32mm which is easier for cleaning. It has isolated construction to measure various fluid media. In addition, a variety of mechanical and electrical configurations are available as standard or customised. This product is available with a choice of constant-current or constant-voltage power supplies.
