Magnetic sensor

Series GF-7030/MA

General

Gräff temperature sensors of the GF-7030/MA series are particularly suitable for use in measuring the temperature on metallic and magnetic surfaces in 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. The magnetic sensor version also offers the advantage that the temperature on magnetic surfaces can be recorded simply but precisely without a measuring hole. As with all Gräff sensors, this series is also manufactured exclusively with a thermal cable instead of a compensating cable. The sensor version GF-7030/MA/W can be used even with the smallest space requirement thanks to the angled version. The sensor and the housing are made of stainless steel as standard.

For permanent attachment, we use a special, very strongly magnetized permanent magnet for this version. Like all Gräff sensors, this version can also be manufactured with all cable availability.
