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.

NIST CALIBRATION available in Product Configurator.

Product Applications

  • Air economizers
  • Outdoor temperature and relative humidity reference
  • Pool room humidity monitoring
  • 2%, 3%, or 5% accuracy models
  • Optional LCD display on duct mount models
  • Radiation shield option for outdoor installation in direct sunlight
