Dwyer OSA RHP-3S11 RHP Humidity/Temperature Transmitter series combines the voltage or current transmitter output with either a passive temperature thermistor or RTD output. Condensation, rain, high humidity, or pollutants don’t affect the polymer power humidity sensor.

Application: 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
