The GE Druck HumiTrac P40250128, GE's next generation relative humidity and temperature transmitter is designed to serve the building automation/HVAC market, as well as a wide variety of general purpose relative humidity monitoring applications. The P40250128 incorporates a NIST traceable, field-replaceable sensor tip, a rugged capacitive sensing element capable of full-scale 0 to 100% RH measurement and a host of field configurable output options.

The HumiTracTM NIST traceable, field-replaceable sensor tip module that allows the end user to replace the sensor on-site and maintain ±2% RH accuracy and NIST traceability. This virtually eliminates the need for time consuming and costly factory calibration, while reducing downtime during service intervals to near zero.

The P40250128 is designed to be highly configurable, even in the field. By minimizing the necessary number of orderable configurations, GE reduces provides maximum flexibility to the installer while cutting down on distributor inventory costs.

The HumiTrac P40250128 features field-selectable outputs (0-5V, 0-10V, 4-20mA) and signal-conditioned temperature from -40 to 60°C. P40250128 is an air mount and has a ±5% humidity accuracy.
