Differential Pizeo Pressure Sensor chips, the main used silicon with high stability. It utilizes silicon oil to transfer pressure from 316L stainless steel diaagm to sensing ing stainless steel to packing and thick film circuit to do temperature compensation and zero correction. It has high reliability and stability.
