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 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. enhanced field serviceability humitrac xr features feld-replaceable relative humidity (rh) sensor tip module that allows the end user to replace the sensor on-site while maintaining 2.5% rh accuracy and nist traceability. 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. unsurpassed sensor performance humitrac xr 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 flter, plus conformal- coated module electronics ensure long life. all sensors undergo a ten hour digital calibration, certifed against a primary nist reference standard. signal conditioned temperature versions maintain specifed rh accuracy across the full operating range of -40f to 140f (-40c to 60c). applications ? energy management systems (ems) ? enthalpy control ? hospitals/labs ? refrigeration control ? pharmaceutical ? evaporative cooling decision potential ? supply air setpoint (condensation prevention) ? economizer effciency ? supermarkets enthalpy is an arbitrary measurement of the relative energy in the air. in this transmitter, it is calculated from the relative humidity and dry bulb temperature measurements. the output is useful in comparing the requisite energy required to heat or cool, and make decisions as to which air stream to use for least energy use to get to design criteria. wet bulb temperature is indicative of a wetted temperature sensor in an air stream. it is the temperature a volume of air would have if cooled adiabatically to saturation at constant pressure by evaporation of water into it, all latent heat being supplied by the volume of air. wet bulb temperature is determined in this transmitter by calculation from the relative humidity and the ambient dry bulb temperature. many building specifcations are surrounding wet bulb measurement, so this transmitter helps provide a direct signal, reducing computing and offoading calculations.
maximum flexibility humitrac xr is designed to be highly confgurable in the feld or in your warehouse. by minimizing the necessary number of confgurations, we reduce distributor inventory costs and provides maximum fexibility to the installer. all versions feature feld-selectable outputs (0 to 5v, 0 to 10v, 4 to 20ma). simple adjustment of slide switches is all that is required. signal-conditioned temperature versions are available scaled from -20f to 120f (-28.8c to 49c) for duct mount and outside air confgurations, or 40f to 90f (4.4 to 32.2c) for space mount confguration. custom ranges are available upon request for high volume applications. humitrac xr is offered in wall mount, duct mount and outdoor air confgurations rugged, attractive enclosures all humitrac xr confgurations feature rugged fame retardant, ul-94v abs plastic. duct and outdoor air versions provide excellent weather resistance (ip42 rated). special care has been taken in the design of the wall mount enclosure to provide enhanced airfow, increasing sensor response time and virtually eliminating the potential of self-heating by transmitter electronics that can lead to decreased accuracy measurements. simple, fast installation all humitrac xr models feature large removable, pluggable terminal blocks, eliminating the need to wire in a confned space and allow the unit to be pre-wired separate from the electronics, an especially attractive feature in unfnished construction, where exposed sensors and electronics could be damaged by moisture, drywall dust and paint. all models incorporate a retaining wire that attaches the cover to the base, allowing the installer to wire the unit without using an extra hand to hold the cover. lowest cost of ownership with a two-year warranty*, simplifed inventory management, reduced installation times and feld-serviceability, humitrac xr sets the standard in reduced cost of ownership and performance-to-price ratio. *transmitter only, one year warranty on replaceable sensor. outside air mount case: abs fame retardant ip42 rated space (wall) mount case: abs fame retardant duct mount case: abs fame retardant ip42 rated probe: stainless steel 2.75 in (70 mm) 3.80 in (96.3 mm) 4.70 in (119.2 mm) 6.38 in (162 mm) 1/2 in (12.7 mm) condiut knockout 2 places 3.80 in (96.3 mm) 4.70 in (119.2 mm) 2.75 in (70 mm) 8.80 in (223.7 mm) 3.80 in (96.3 mm) 4.70 in (119.2 mm) 4.70 in (119.2 mm) 1.28 in (32.4 mm) 3.52 in (89.5 mm) 0.46 in (11.7 mm) outside air mount case: abs flame r etar dant ip42 rat ed space (wall) mount case: abs flame r etar dant duct mount case: abs flame r etar dant ip42 rat ed pr obe: stainless st eel wiring access cove r base ? ? ?
