Flush Diaphragm Pressure Sensor

Date: 2021-Sep-07

For pressure measurement of viscous media, the pressure hole of thread on the pressure sensor may be blocked by the media after long time use, thus, affecting the accuracy eventually. The flush diaphragm pressure sensor has the sensing membrane at the forefront of the connecting thread which can contact the measuring medium in a large area without clogging. It is easy to clean even the corrugated diaphragm has residual stains or scaling, therefore, the pressure sensor’s lifetime is extended.
