Belimo Cable Temperature Sensor 4-20 mA - Probe 50x6 mm - 2 Metres - 22CT-14H
The Belimo 22CT-14H is an active cable temperature sensor designed for measuring temperatures in both air ducts and pipes. The sensor features a stainless steel probe and a special cable for gap installations, making it easy to install even in hard-to-reach locations. The PT1000 class AA sensor element ensures precise measurement, while the 4-20 mA output signal provides reliable performance over long cable runs. With eight adjustable measuring ranges, the sensor is highly versatile for a wide range of HVAC applications.
Benefits and Features
- Active 4-20 mA output signal: The current signal is immune to interference on the cabling and compatible with virtually all common control equipment and building management systems.
- PT1000 class AA sensor element: Provides stable and accurate temperature measurement with an accuracy of ±0.5°C at 21°C.
- Suitable for both air and water: The sensor can be used in air ducts as well as pipes, offering broad applicability across HVAC systems.
- Eight adjustable measuring ranges: Eight measuring ranges from -50 to +250°C can be selected via a plug-in jumper, customised to specific applications. The factory default is 0 to +160°C.
- Special cable for gap installations: The flexible 2-metre cable allows installation in difficult-to-access locations within systems.
- IP65 / NEMA 4X protection rating: Fully protected against dust and water jets, suitable for use in technical rooms and humid environments.
Installation, Maintenance and Applications
The stainless steel probe measuring 50 mm in length and 6 mm in diameter is ready for direct installation in air ducts. Electrical connection is made via a pluggable terminal block (max. 2.5 mm²). The sensor is suitable for use in air handling units, pipe networks, and climate control installations in commercial and industrial buildings.
Practical Information
The sensor is equipped with a stainless steel probe of 50 mm length and 6 mm diameter, with a fixed 2-metre connection cable. The medium temperature range is from -50 to +180°C. The nominal voltage is DC 24 V. The sensor weighs 0.20 kg and features a UV-resistant polycarbonate casing with an NBR seal.
