BELIMO 22DT-14N

In modern HVAC, building automation and industrial process systems, accurate and robust temperature measurement is crucial for ensuring comfort, energy efficiency and system stability. The BELIMO 22DT-14N sensor is engineered to meet these demands. With its active 4–20 mA output, it can seamlessly integrate into standard building control or PLC systems without requiring additional signal conversion. Its 150 mm stainless-steel probe length and narrow 6 mm diameter allow easy insertion into ducts or pipes (with thermowell), enabling direct measurement of air or fluid temperature. The device supports eight selectable measuring ranges (from –50 °C to +250 °C) so you can tailor it to your specific application rather than buying multiple sensors. Housed in a robust IP65 / NEMA 4X enclosure, it’s built for harsh environments—dust- and water-resistant for use in plant rooms or external ducts. Compared with passive sensors or 0–10 V output units, the 22DT-14N delivers higher accuracy (±0.5 °C typical at 21 °C) and more flexibility. Whether monitoring supply air in an HVAC duct, checking chilled-water line temperature, or driving a BAS for temperature-based control, this sensor offers a superior combination of reliability, performance and ease of integration. Its spring-loaded terminal block simplifies wiring and supports rapid commissioning, making it an excellent choice for professional installations where accuracy and durability matter.
