HTF
The sleeve sensor ⁄ cable temperature sensor THERMASGARD
®
HTF is used for the detection
of temperatures in liquid and gaseous media, e.g. by installing it in an immersion sleeve.
The cable sensor can be implemented as immersion or duct sensor, with silicone, glass fibre,
or PVC leads, for two-wire, three-wire, or four-wire connection, depending on the application.
The sleeve length varies, depending on request, from 30 ... 500 mm (standard is 50 mm respectively
200 mm), the cable length is arbitrary (standard is 1.5 m).
