The IKF1 industrial installation duct sensor is used to measure the temperatures of liquids and gases in pipelines, air ducts or containers in machines, apparatus, and plant construction. For use in air ducts, the mounting flange (MF) is required. For use in liquids, immersion sleeves made of nickel-plated brass (THMs) must be used. For aggressive media, immersion sleeves made of stainless steel V4A (THV) are recommended. Immersion sleeves or mounting flange are not included in the scope of delivery and must be ordered separately as accessories.
