CSS20 Differential Pressure Sensor

Description

CSS20 is piezoresistive silicon differential pressure sensor, the main element is a diffused silicon with high stability. It utilizes silicon oil to transfer pressure from 316L stainless steel diaphragm to sensing element. It has high stability, good reliability ,high static pressure. It is widely used in field which measure differential pressure.
