The Belimo duct and immersion temperature sensor is designed for measuring air and water temperatures in HVAC systems and can also be used in piping when combined with an immersion sleeve. The stainless steel probe and housing provide a stable and protected installation. The passive Ni1000TK5000 element accurately converts the measured temperature into a resistance signal that is processed by the control system. Based on this measured value, the system is automatically controlled to maintain a consistent and efficient climate regulation.
The sensor is suitable for mounting in air ducts and can be used in pipes when paired with an immersion sleeve. Correct positioning of the probe ensures a representative temperature measurement within the medium. The housing enables a safe and organized connection via the terminal block. Due to its passive design, no power supply is required. The sensor is used in commercial buildings, residential construction, and industrial HVAC systems where reliable temperature measurement is necessary.
The sensor features a stainless steel probe with a length of 100 mm and a diameter of 6 mm, providing sufficient insertion depth for reliable temperature measurement within the duct or medium. The housing is made of impact-resistant plastic and includes a cable gland with strain relief for dependable connections. The Ni1000TK5000 element directly transmits the resistance signal to the controller. This version is suitable for both duct and pipe applications where robust installation and stable measurement are required.
