Series GF-7112

General

Gräff temperature sensors of the GF-7112 series are particularly suitable for use in temperature measurement on extrusion systems and in tool and machine construction. 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 measuring sleeve and the connection line are made of high-quality stainless steel 1.4571 and not made of galvanized steel. Especially for the connecting cable, we only use high-quality and selected thermal material, which guarantees an accuracy of better than 1.5K even after use. In addition to a large number of measuring sleeve designs with a diameter of 4.76mm to 10.00mm, we also have a large number of fastening options with or without a thread adapter. For improved anti-kink protection of the cable, there is always an anti-kink spring that can be up to 10,000mm long. Of course, a stainless steel cable with a PTFE jacket is also being used more and more, since the positive effects of the anti-kink protection and a moisture-resistant design characterize the robustness of these sensors. Please also ask about our specially thermally insulated versions.
