Ceramic Pressure Transmitter
The Ceramic Pressure Transmitter uses air venting in the cable connection to eliminate liquid pressure with air pressure. Once immersed, the transmitter's fluid pressure will be greater than the air pressure. Because of this, the diaphragm tends to become slightly distorted. This distortion is invisible to the human eye, but it may be identified with piezoresistive sensors. Trumen Ceramic Pressure Transmitter identifies liquid pressure in this way.
