Resistance thermometer
Resistance thermometer with bayonet lock and immersion sleeve

Series GF-7140

General

Gräff temperature sensors of the GF-7140 series are particularly suitable for use in measuring the temperature of liquids in pipes, tanks and containers, 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 version with a closed immersion sleeve offers the advantage that the medium to be detected remains in the closed circuit even when the sensor is replaced. Thanks to a suitable bayonet lock, the sensor can always be changed quickly, even during the
process. The installation lengths can be freely selected and can therefore be adapted to any application and process depth. As with all Gräff sensors, this series is also manufactured exclusively with a thermal cable instead of a compensating cable. All sensor components are mainly made of high-quality stainless steel 1.4571.
