Temperature sensors /Thermocouple

Thermocouple
Melt- & mass temperature

Series GF-7043

General

Gräff temperature sensors of the GF-7043 series are particularly suitable for use in temperature measurement on extrusion systems, in tool and machine construction and in the injection molding area. As one of the first German manufacturers and with more than 50 years of experience in the field of melt temperature measurement, we know that not all melts are the same and therefore not all sensors are the same. High-quality materials and a special manufacturing process characterize this product. A special feature of this series is the enormous range of possibilities that can be implemented to suit the respective requirements. In addition to the standard process connections such as 1/2”-20UNF-2A, M18x1.5, M10, M14x1.5, all connection sizes can be realized and manufactured. Specially developed measuring tips make it possible, even under difficult process conditions or when using difficult materials, to record the process variable temperature with great precision! Of course, the service life of our sensors can be extended enormously with special coating options. Even versions made of special materials such as Hastelloy and Inconel are standard with us.
