CSS26 Piezoresistive Silicon Pressure Sensor
Description
CSS26 is piezoresistive silicon 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 and fulfill air and liquid pressure measurement.
