.jpg) | Series WHP Wireless Humidity/Temperature Sensor Transmits up to 100 Feet, Battery Operated The Series WHP Wireless Humidity/Temperature Sensors provides flexibility in locating sensors and reduces wiring cost. Using a 418 MHz transmitter, the sensor can transmit data up to 100 feet without the use of a repeater. When coupled with a receiver and output module, the Series WHP can output voltage, current or resistance values for humidity and temperature. Since the unit is battery powered using two AA batteries, users can change the location of the sensor by a couple of feet or to a different wall without worry about extra labor cost. With the transmit rate at approximately one reading every 10 seconds, the battery is estimated to last 5 to 8 years. The duct mount and outside air mount sensors come standard with sintered filters to protect the sensor from particulates. Set point adjustment and/or manual override buttons are available on wall mount sensors. Additional Info: http://www.dwyer-inst.com/Product/Humidity/Sensors/SeriesWHP   | ||||||||
.jpg){kind=spacer} | Series HHT Hazardous Area Humidity/Temperature Transmitter Intrinsically Safe or Explosion-Proof Models The Series HHT Hazardous Area Humidity/Temperature Transmitter takes accurate measurements in the harshest of environments. The transmitter is offered in explosion-proof and intrinsically-safe versions depending on the application's requirements. The explosion-proof model is offered with 4 to 20 mA output for humidity only. The intrinsically-safe version is offered with 4 to 20 mA output for humidity and temperature. Both versions have an optional two line alphanumeric display to show the current humidity and temperature. The Series HHT humidity/temperature transmitter is excellent for offshore HVAC applications, dust and grain applications. Intrinsically safe models require an intrinsically safe barrier. | ||||||||

The polymer capacitance humidity sensor is not affected by condensation, fog, high humidity, or contaminants. The humidity sensors are available with 2% or 3% accuracies. Duct mounted transmitters are available with an optional two-line alpha numeric LCD display. The Series RHP is available with interchangeable filter options as well as replaceable sensors. Application Note: For duct mount installations, the sintered filter option should be ordered for applications where the humidity transmitter is mounted in the supply air duct after the fan and cooling coils. | ||||||||
.jpg){kind=spacer} | Series RH/RHL Humidity/Temperature Transmitter Calibration-Free, 2% Or 3% Accuracy, Optional Display Demanding humidity/temperature applications require the Series RH/RHL Transmitter which offers high accuracy, long term stability, and reliable operation. The Series RH/RHL is designed for monitoring and controlling humidity or both humidity and temperature in building energy management systems, HVAC, commercial, residential, clean rooms, museums, climate chambers, and other space monitoring applications. The Series RH/RHL is a two-wire transmitter with a 4-20 mA loop powered output or 0 to 10 VDC output. The state of the art sensor recovers from 100% saturation and is calibration-free. A variety of mounting configurations are available including wall mount, duct mount, and OSA (outside air) models. Select humidity monitoring or humidity and temperature models. The combined humidity/temperature version (RHT) provides dual 4-20 mA or 0 to 10 VDC output signals to control both humidity and temperature with one sensor which reduces installation costs. The duct mount version is also available with an optional alpha-numeric LCD to provide local indication of humidity and temperature simultaneously. The displayed temperature is field selectable for °F or °C. Monitor humidity in ducts, rooms, and outside air. | ||||||||
