The Helios TFKB is a duct temperature sensor with an integrated limiting function, specifically developed for use in ventilation and HVAC systems. Its primary role is to monitor and control air temperature within ducts to prevent overheating and ensure safe system operation.
Ideal for applications requiring thermal protection, the TFKB acts as a safety component that limits temperature to a predefined threshold. When the air temperature exceeds this set point, the sensor triggers a protective response, helping to prevent equipment damage or unsafe conditions. The TFKB is suitable for integration in systems where air heating elements are present or where temperature-sensitive operations must be maintained.
