The sleeve sensor / cable sensor THERMASGARD® HTF is used to detect temperatures in liquid and gaseous media. It can be used as a duct sensor and - if installed in an immersion sleeve - as an immersion and screw-in sensor. The sleeve length varies, depending on request, from 30...500 mm (standard is 50 mm or 200 mm), the cable length is arbitrary (standard is 1.5 m). Depending on application, with silicone, glass fibre, or PVC leads, for two-wire, three-wire, or four-wire connection.
