Resistance thermometer
Surface sensor with brass retaining plate

Series GF-7131/MS

General

Gräff temperature sensors of the GF-7131/MS series are particularly suitable for use in temperature measurement on tools, engines, cooling systems, heating blocks, thermoblocks, heating systems, etc. from the fields of plastics technology, the pharmaceutical industry, power plant technology, heating and cooling technology, chemical plants and mold making. Due to the combination of high-quality materials, there are no limits to this series, and the flat sensor design also offers the advantage that the sensor can be fixed without any additional drilling. As with all Gräff sensors, this series is also manufactured exclusively with a thermal cable instead of a compensating cable. A special manufacturing process enables very fast and precise temperature measurement. Due to the targeted material combination of stainless steel and brass, the temperatures to be measured are recorded very quickly and precisely.
