CSS30 Piezoresistive Silicon Pressure Sensor
Description
CSS30 is piezoresistive silicon pressure sensor, the main element is a diffused silicon with high stability. The measured pressure is transferred from 316L stainless steel diaphragm to sensing element via silicon oil, utilizing the piezoresistance effect of diffused silicon to transfer pressure to voltage signal and fulfills pressure measurement .It is a full-welded pressure sensor, Pressure port can be selected by user. It can be used for kinds of field.
