Resistance thermometer
Surface sensor with pipe clamp fixing

Series GF-7122

General

Gräff temperature sensors of the GF-7122 and 7122/A series are particularly suitable for use in temperature measurement on pipes, shafts, circular storage tanks and heating systems, etc. from the fields of plastics technology, the pharmaceutical industry, power plant technology, heating and cooling technology, chemical plants and mold making.
Thanks to the combination of high-quality materials, there are no limits to this series. In addition, the version with an axial or radial cable outlet offers the possibility of measuring the temperature even at inaccessible measuring locations. As with all Gräff sensors, this series is also manufactured exclusively with a thermal cable instead of a compensating cable. In addition to the standard pipe clamp diameters of 16 mm to 130 mm, there is also the option of using pipe clamp bands to achieve larger diameters up to a diameter of 1000 mm. All sensors of the GF-7022 and GF-7022/A series are generally made of stainless steel 1.4571 with a corresponding cable, also waterproof or splash-proof,
so these sensors can also be used under very rough operating conditions.
