Description
In outdoor HVAC and building-automation systems, reliable, accurate sensing of both humidity and temperature is crucial to control ventilation, free-cooling, dehumidification and energy-efficiency routines. The BELIMO 22UTH-53 addresses this need by delivering dual active 4–20 mA outputs—one for humidity (which can represent RH, absolute humidity, dew point or enthalpy) and one for temperature—thereby replacing the need for separate sensors and converting signals for your control system. The field-selectable measuring ranges (from -40… 60 °C up to -20… 80 °C) allow adaptation to varied outdoor conditions. The sensor uses a polymer-based capacitive humidity element with a stainless steel wire mesh filter for durability and precision. The weather-shielded enclosure rated IP65 / NEMA 4X ensures long-term performance outdoors, resisting rain, dust and other environmental stressors. For example, the 22UTH-53 can be mounted on an external wall or pipe rack to feed your building-automation system with real-time humidity and temperature data for economizer logic, enthalpy-based control, or outdoor-air monitoring. Compared to simpler indoor sensors or separate units, this all-in-one device simplifies wiring, reduces installation time, and delivers professional specification accuracy (± 2% RH typical) in demanding outdoor environments. belimo.com+2zotsupply.com+2
