The Relative Humidity and Temperature Transmitters RHT-WM are microprocessor-based instruments that incorporate high-accurate and stable sensors whose information is converted to linear 4-20 mA or 0-10 Vdc. As they are microprocessor equipment, they can be totally configured through the communication interface ATxConfig and ATxConfig software. The humidity output can be configured to represent the Relative Humidity measured or the temperature value at dew point.
The RHT-WM model is intended for wall mounting. The RHT-DM comes with a
probe tip for duct or wall mounting.

GENERAL SPECIFICATIONS
Power supply12 Vdc to 30 Vdc (4-20 mA model) or 18 to 30 Vdc (0-10 V
model)
Outputs:4-20 mA or 20-4 mA current, 2-wire loop power supply, 0-10
Vdc voltage (optional)
OUT1 output resolution:0.006 mA (4-20 mA) or 0.003 V (0-10 V);
OUT2 output resolution:0.022 mA (4-20 mA) or 0.015 V (0-10 V);
