Belimo 22UTH-53 : Outdoor Humidity and Temperature Combo Sensor, 2% Accuracy, RH Outputs: 4-20mA, Temperature Transmitter 4-20mA Output, Includes Weather Shield, NEMA 4X / IP65 Protection
The 22UTH-53 Outdoor Sensor with Weather Shield is an active sensor designed for accurate measurement of relative or absolute humidity and temperature in outdoor areas. Enclosed in a rugged 4X / IP65 rated housing, this sensor is well-suited for outdoor installations, offering protection against dust and water ingress. The sensor utilizes a polymer capacitive sensor with a stainless steel wire mesh, ensuring reliable and consistent readings. Users have the flexibility to select either humidity, enthalpy, or dew point as the output signal. The output signals are active and transmitted as a 4...20 mA current, making it compatible with various control systems. The 22UTH-53 offers four measuring ranges for humidity and temperature, providing adaptability for different environmental conditions. The accuracy of the sensor is impressive, with humidity accuracy at ±2% between 0...80% RH at 77°F and temperature accuracy at ±0.3°C at 25°C. Powered by a DC 24 V source, the sensor consumes 1 W of power. Installation is made easy with pluggable spring-loaded terminal blocks and a cable gland with strain relief. However, users must ensure that the sensor is used within its specified field of application and unauthorized modifications are strictly prohibited to ensure safe and reliable operation.
