HumiTrac XR Telaire Dew Point, Enthalpy, Wet Bulb, and Temperature Transmitters Features Benefits Microprocessor-based signal processing Improves indoor air quality (IAQ) Excellent accuracy Saves energy Weather resistant duct and outside air Helps prevent mold growth mounting Provides a more comfortable environment Easy to install Helps prevent condensation within a building Field-replaceable RH sensor saves time Supplies more useful information on the Multiple user selectable outputs indoor/outdoor environment to help building operators make better decisions Robust, proven capacitive sensor technology Optimizes industrial environments like Attractive, modern look and rugged pharmaceutical plants and clean rooms packaging Versatile temperature measurement Temperature compensated Low cost of ownership, very economical Two-year transmitter warranty and one year sensor warranty RoHS compliant Amphenol Advanced SensorsApplications Enthalpy is an arbitrary measurement of the relative Energy Management Systems (EMS) energy in the air. In this transmitter, it is calculated from the relative humidity and dry bulb temperature Enthalpy control measurements. The output is useful in comparing the requisite energy required to heat or cool, and Hospitals/labs make decisions as to which air stream to use for least energy use to get to design criteria. Refrigeration control Wet Bulb temperature is indicative of a wetted temperature sensor in an air stream. It is the Pharmaceutical temperature a volume of air would have if cooled adiabatically to saturation at constant pressure by Evaporative cooling decision potential evaporation of water into it, all latent heat being supplied by the volume of air. Wet bulb temperature Supply air setpoint (condensation prevention) is determined in this transmitter by calculation from the relative humidity and the ambient dry bulb temperature. Many building specifications Economizer efficiency are surrounding wet bulb measurement, so this transmitter helps provide a direct signal, reducing Supermarkets computing and offloading calculations. HumiTrac XR Transmitters are 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 unitss microprocessor computes the dew point, wet bulb, or enthalpy. 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 Enhanced Field Serviceability this transmitter from relative humidity and dry bulb temperature sensors, the output can be used in a HumiTrac XR features field-replaceable Relative variety of applications. HVAC systems can keep a Humidity (RH) sensor tip module that allows the end building in a narrow range of dew point at far less user to replace the sensor on-site while maintaining expense and complexity than one, which controls 2.5% RH accuracy and NIST traceability. The user relative humidity in a narrow range. Unlike relative simply powers off the unit, installs the new sensor humidity, the dew point is not affected by changes module and powers back the unit. This virtually in dry bulb temperature as the air moves through eliminates the need for time consuming and costly equipment and the building. factory calibration, while reducing downtime during service intervals to near zero. Dew point is a measure used in applications for humidity control to avoid condensation of Unsurpassed Sensor Performance water on cooler surfaces within a building (e.g. windows, refrigeration cases, inside walls, HumiTrac XR utilizes a rugged capacitive sensor electronic equipment, and ductwork). This type of that provides full-scale 0-99% RH measurement condensation can lead to discoloration, physical/ with unsurpassed response times, linearity and structural damage, and mold/mildew growth. stability. Recovery to condensation and chemicals Dew point control provides a more comfortable is excellent and an integrated filter, plus conformal- environment, energy savings, and better indoor air coated module electronics ensure long life. All quality. sensors undergo a ten hour digital calibration, certified against a primary NIST reference standard. Signal conditioned temperature versions maintain specified RH accuracy across the full operating range of -40F to 140F (-40C to 60C).
