Resistance thermometer
Screw in sensor with connection head, graduated

Series GF-8101 & GF-8101/A

General

Gräff temperature sensors of the GF-8101 series are particularly suitable for use in fast temperature acquisition in industrial plants, furnaces and mechanical engineering. Thanks to the use of high-quality materials and our special manufacturing process, these sensors can be used at temperatures of up to 600°C. Even in the standard version, the protective tube and the thread are made of high-quality stainless steel 1.4571. The GF-8101 design can be designed both as a vibration-proof version and with an exchangeable measuring insert. The protective tube diameter can be freely dimensioned between 6.0 and 12.0 mm. A specially graded measuring sleeve enables rapid process temperatures to be recorded. Of course, all sensors of type GF-8101 can optionally be manufactured with a head transmitter to provide a standard signal (0-10V / 4-20mA). In addition to the standard BK connection head, we also manufacture this version with an easy-to-install KK connection head. In the GF-8101 version, there is a neck tube (intermediate piece) between the screw-in thread and the connection head for thermal protection of the connection head.
