Introduction
MPM270 high stable and high accurate piezoresistive sensor uses the specified die which is of excellent stability and high accuracy. And well processed with optimizing assembly technology, it is able to provide users a pressure sensor element with high stability, superior performance and good repeatability. It adopts the same shape, mounting dimensions and sealing method as that of our other similar products, so it is highly interchangeable. MPM270 is widely used for pressure measurement of media that is compatible with stainless steel and EPDM rubber.
