The GE HUMI-DP-XR-S HumiTrac XR Transmitter is rugged, compact and ideally suited for monitoring dew point, wet bulb, enthalpy or temperature in building automation and process applications. Using a capacitive RH sensor, the units’s microprocessor computes dew point.


Dew Point temperature is the temperature at which any given volume of air must be cooled in order that water vapor will condense into water. Calculated in this transmitter from relative humidity and dry bulb temperature sensors, the output can be used in a variety of applications. HVAC systems can keep a building in a narrow range of dew point at far less expense and complexity than one, which controls relative humidity in a narrow range. Unlike relative humidity, the dew point is not affected by changes in dry bulb temperature as the air moves through equipment and the building.


Dew point is a measure used in applications for humidity control to avoid condensation of water on cooler surfaces within a building (e.g. windows, refrigeration cases, inside walls, electronic equipment, and ductwork). This type of condensation can lead to discoloration, physical/structural damage, and mold/mildew growth. Dew point control provides a more comfortable environment, energy savings, and better indoor air quality.


The HUMI-DP-XR-S features a field-replaceable Relative Humidity (RH) sensor tip module that allows the end user to replace the sensor on-site while maintaining ±2.5% RH accuracy. The user simply powers off the unit, installs the new sensor module and powers back the unit. This virtually eliminates the need for time consuming and costly factory calibration, while reducing downtime during service intervals to near zero.


The HUMI-DP-XR-S utilizes a rugged capacitive sensor that provides full-scale 0-99% RH measurement with unsurpassed response times, linearity and stability. Recovery to condensation and chemicals is excellent and an integrated filter, plus conformal-coated module electronics ensure long life. Signal conditioned temperature versions maintain specified RH accuracy across the full operating range of -40° F to 140° F (-40° C to 60° C). The transmitter also comes with a space mounting configuration.
