Wired Ceramic Moisture Sensor Transmitter
FM and CSA certified, low cost, two-wire, intrinsically safe dew point transmitter for continuous measurement of the moisture content in inert gases or safe classified areas. Power can be from any 12 to 28 VDC source. The sensor can be installed directly in a main gas line or in a sample stream. Only periodic recertification is required to maintain calibration accuracy.
