The pressure transmitter contains a built - in ceramic sensor that has a Wheatstone resistance bridge. Manufacturers assemble an electronic circuit together with the sensor in a stainless steel enclosure for these pressure transmitters.

Additionally, the connecting cable includes a vent pipe that has a humidity filter to prevent the build - up of condensation. A protective cap shields the diaphragm from external influences. The enclosure houses the sensor, the electronics, and the connecting cable, and has small dimensions. The manufacturer has temperature - compensated the pressure transmitter for a wide temperature range.
