Flush Diaphragm Pressure Sensor

Date: 2021-Sep-07

For pressure sensors that have been used to measure viscous media for a long time, the pressure hole of its thread will likely be blocked by the medium. This affects the accuracy of the measurement. The sensing diaphragm of the flush diaphragm pressure sensor is at the front of the connecting thread. This design allows large areas of contact with the measuring medium without clogging. Residue or scale on the diaphragm is also easy to clean. This extends the life of the pressure sensor.
