OUTSIDE AIR HUMIDITY RADIATION SHIELDS6 or 10 Plate Design, Integral Pipe Mounting Kit243Ø5-1/8[130.18]Ø4-47/64[120.25]6-13/64[157.65]10-37/64[268.73]Humidity/TemperatureTransmittersAIR QUALITYThe Series RHRS Outside Air Humidity Radiation Shields protects outside air humidity transmitters from rain and radiated heat. With the curved shape and color of the plates, air flow is able to move across the sensor to keep radiated temperatures from rooftops and surrounding surfaces from affecting humidity readings. FEATURES/BENEFITS• Adjustable sensor mounting collar works with Dwyer RHP sintered filter outdoor air humidity transmitters or other RH devices• Universal mount fits 3/4˝ to 1-1/2˝ pipe or flat surfacesAPPLICATIONS• Building outside air reference• Weather stationsPicture shown withSeries RHP HumidityTransmitter* (sold separately)ø5-1/8[130.18]4-31/32[126.21]8-43/64[220.27]ø4-47/64[120.25]RHRSRHRS-10WEATHER-RESISTANT HUMIDITY/TEMPERATURE TRANSMITTERCompact Housing, Sintered Filter2X 5/16 [7.94]4[101.6]3-31/64[88.5]3[76.2]4-9/16[115.89]2-3/4[69.85]1-31/64[37.70]1-27/64[36.12]The compact Series WHT Weather-Resistant Humidity/Temperature Transmitter is designed to withstand the elements. A removable sintered filter protects the polymer capacitance sensor from solid objects that may come in contact with the transmitter. The transmitter is available with 4 to 20 mA or 0 to 10 VDC output signals for both temperature and humidity. This transmitter is ideal for measuring outside air temperature and humidity levels for air handling economizer applications.FEATURES/BENEFITS• RH or RH and temperature outputs• Compact NEMA 3S constructionAPPLICATIONS• Air handling economizers• Air environment monitoring in agriculture or livestock cultivation housesSPECIFICATIONSRelative Humidity Range: 0 to 100% RH.Temperature Range: -40 to 140°F(-40 to 60°C).Accuracy, RH: ±3% 20 to 80% RH, ±4% @ 10-20%, 80 to 90%.Accuracy, Temp Models with 4 to 20 mA Temp.
