RHP Humidity and Temperature Transmitter, For Industrial Automation, Style : Head Mounted

RHP Humidity and Temperature Transmitter

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. Featuring polymer capacitance humidity sensors, models are available in 2%, 3% or 5% accuracies. Duct mounted transmitters are available with an optional two-line alpha numeric LCD display.

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.
