Belimo 22UTH-530B : Outdoor Humidity and Temperature Combo Sensor, 2% Accuracy, RH Outputs: 4-20mA, 1K Platinum RTD, Includes Weather Shield, NEMA 4X / IP65 Protection
The 1K Platinum RTD option on the Belimo 22UTH-530 series is an outdoor sensor with a weather shield designed for measuring relative or absolute humidity and temperature in outdoor areas. The sensor features a polymer capacitive sensor with stainless steel wire mesh, ensuring accurate readings. It offers 4-20mA outputs for humidity and temperature signals, and users can select enthalpy or dew point as the output signal instead of humidity. The device operates at AC/DC 24 V power supply and comes with a pluggable spring-loaded terminal block for electrical connections. It is enclosed in a NEMA 4X / IP65 rated housing, ensuring protection against harsh weather conditions. The sensor has a measuring range of 0-100% RH for humidity and -30 to 120°F (-35 to 50°C) for temperature, with an accuracy of ±2% RH and ±0.5°F at 32°F, respectively. It is suitable for use in air plenums and complies with various safety standards and certifications. However, the device must not be used outside its specified field of application, and unauthorized modifications are prohibited.
