SERIES RHP-E/N | HUMIDITY/TEMPERATURE/DEW POINT TRANSMITTER

European style

North American style

BENEFITS/FEATURES

• Reduced installation cost with combined humidity/dew point and temperature sensing

• Wide application environments from a large selection of temperature sensors and 2% and 3% accuracies

•Reducedinventorywitheldselectableoutput

DESCRIPTIONAPPLICATIONS

• Air economizers

• Room comfort monitoring

• Greenhouse monitoring

The Series RHP-E/N Wall Mount Humidity/Temperature/Dew Point Transmitter is the most

versatile room transmitter on the market. The stylish housing is well vented to provide air ow across the sensor to improve measurement accuracy. The humidity and the dew point are measured using a capacitive polymer sensor that completely recovers from 100% saturation. The humidity and dew point can have either a current or voltage output, while the optional temperature output can be a current, voltage, RTD, or thermistor. For models with current or voltage for the temperature output, the temperature range is eld selectable.
