Resistance thermometer
High temperature ceramic sensor 22mm

Series GF-8107

General

Gräff temperature sensors of the GF-8107 series are particularly suitable for use in temperature measurement in high-temperature processes in furnaces and in the steel industry. Thanks to the use of high-quality materials and our special manufacturing process, these sensors can be used at temperatures of up to 700°C. Even in the standard version, the protection tube is made of high-quality ceramic material. The GF-8107 design is generally manufactured in a vibration-proof design. The protective tube diameter of this series is 15 mm.Of course, all sensors of type GF-8107 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 addition to a standard screw connection, there are also gas-tight screw connections and various clamping flanges available for the process connection.
