The Belimo duct and immersion temperature sensor is designed for measuring air and water temperatures in HVAC systems. The sensor is used in air ducts and, in combination with an immersion sleeve, can also be applied in pipe installations. The fixed stainless steel probe and housing ensure a stable and protected mounting. The passive PT1000 element accurately converts the measured temperature into a resistance signal that is processed by the control system. Based on this measurement, the system is automatically regulated for consistent and efficient climate control.
The sensor is suitable for mounting in air ducts and can also be applied in pipes using an immersion sleeve. Correct positioning of the probe ensures a representative temperature measurement in the medium. The housing allows for a safe and tidy connection via a plug-in terminal block. Due to its passive design, no power supply is required. The sensor is used in commercial, residential, and industrial HVAC systems where reliable temperature measurement is essential.
The sensor features a stainless steel probe with a length of 100 mm and a diameter of 6 mm. The housing includes a plug-in terminal block and cable gland with strain relief for reliable connection. The PT1000 element transmits the resistance signal directly to the controller. This version is suitable for both duct and pipe applications requiring robust mounting and stable measurement.
