Resistance thermometer
Surface sensor with brass – segment

Series GF-7131

General

Gräff temperature sensors of the GF-7131 series are particularly suitable for use in temperature measurement on tools, motors, 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. In addition, the design as a segment sensor offers the advantage that the temperature on surfaces can be recorded simply but precisely by attaching two standard M4 bores. 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. Thanks to the nickel-plated surface, the brass segment is protected against external influences and not wanted heat influence.
