Dwyer Series WHP

Series WHP Wireless Humidity/Temperature Sensor

Transmits up to 100 Feet, Battery Operated

The Dwyer 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, 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.
