Series GF-8104

General

Gräff temperature sensors of the GF-8104 series are particularly suitable for use in temperature measurement on furnaces, containers and pipelines. Due to the use of high-quality materials and our special manufacturing process, these sensors can be used at an operating pressure of up to 700 bar. Even in the standard version, the protective tube and the thread are made of high-quality stainless steel 1.4571 or heat-resistant steel 1.4762. The GF-8104 design is generally manufactured in a vibration-proof design. The protective tube diameter of this series is adapted to the corresponding welding sleeve and is therefore suitable for welding sleeves of form 4 or also known as form “D”. Of course, all sensors of type GF-8003 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 or DANA connection head.
