Relative Humidity/Temperature Transmitters

Stand-alone Relative Humidity/Temperature transmitters with 4-20mA interface are easy-to-install for indoor and outdoor applications. Both options offer two 4-20mA outputs for temperature and relative humidity readings.

In addition to relative humidity and temperature, the humidity channel can be configured to output:

• – Wet-bulb temperature
• – Enthalpy
• – Dew point

These transmitters combine easy installation and minimal maintenance with accurate, reliable measurement.

Applications:

Industrial automation, agriculture, electrical power generation

Outdoor RH/Temperature Transmitter

The outdoor Relative Humidity/Temperature Sensor provides two 4-20mA outputs for Temperature and Relative Humidity readings. The humidity channel can be configured to output Relative Humidity, Wet Bulb Temperature, or Dew Point Temperature. The sensors are installed in a radiation shield that includes a mounting clamp.
