Humidity transmitters for building automation systems RHT relative humidity transmitters are engineered for building automation systems in the HVAC/R industry. The RHT measures relative humidity (rH), and temperature (T). RHT devices are available with large touchscreen display making configuration of the device quick and easy. RHT devices include: • Separate field configurable output for each measurement parameter (rH and T) • Proportional output options including: voltage (0–10 V, 2–10 V) and current (4–20 mA) • Offset feature enabling field calibration for each measurement parameter (rH, T) RHT series device options offer: • 2” x 3” touchscreen display • Field configurable relay for any of the two parameters • Modbus configuration Technical details Accurary: Temperature:
