Description

PD790-12M2 is a highly stable and reliable piezo-resistive pressure sensor with wide temperature compensation and zero correction. It contains a highly stable silicon die, stainless steel 316L housing with diameter 19 mm. The measured differential pressure is transmitted onto the silicon die through the 316L diaphragm and inner media. This transforms the measured pres- sure into an electrical signal.
