Resistance thermometer
Screw in sensor with DSTM12x1 plug

Series GF-7138/S

General

Gräff temperature sensors of the GF-7138/S series are particularly suitable for use in temperature measurement in pipelines and liquid containers. Thanks to the use of high-quality materials and our special manufacturing process, these sensors can be used at temperatures of up to 200°C. Even in the standard version, the measuring sleeve and the connection head are made of high-quality stainless steel 1.4571. A special geometry and the selection of the diameter enable very precise and very fast temperature measurement of liquids, both directly in pipelines and in liquid containers. Due to the special burr and edge-free measuring sleeve design, there is no risk of residues settling on the surface. In addition, there is the option of protecting the measuring sleeve against abrasive “liquids” with a special coating. This series GF-7138/S is equipped with a G1/2” process connection as standard. It goes without saying that
this series is manufactured exclusively with a thermal cable. For further data processing, there is a DIN M12 plug, 4-pin, permanently installed on the sensor.
