About the MPM280 Pressure Sensor

MPM280 piezoresistive pressure sensor has a robust housing made of stainless steel, 316L, giving them optimum long-term stability for a range of OEM applications. The stainless steel 316L corrugated diaphragm is welded on the front, separating off the pressure sensing chip, which is made of silicon, from the measuring medium. Every silicon oil-diffused type pressure sensor is measured over the entire pressure and temperature datasheet and is supplied with a specification label.

The outline, installation dimension, and sealing method of General MPM280 are strongly interchangeable, it is widely used for measuring pressure which is compatible with stainless steel and FKM
