Cảm biến nhiệt độ và độ ẩm - Series RHP

Series RHP
Humidity/Temperature Transmitter
Passive Temperature Outputs, Sintered Filter Options

The Series RHP Temperature and Humidity Transmitter combine the voltage or current humidity transmitter output with a passive temperature thermistor or RTD output. 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.

For models with resistive thermistors or RTD outputs, please click here for temperature to resistance lookup tables.

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.
