Series GF-7003

General

Gräff temperature sensors of the GF-7003 series are particularly suitable for use in temperature measurement on tools, engines, cooling systems, heating blocks, thermo blocks, 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 design with measuring pins offers the advantage that the temperature can also be recorded simply but precisely under surfaces by attaching two standard bores. As with all Gräff sensors, this series is also manufactured exclusively with a thermal cable instead of a compensating cable. In the case of surface sensors without a measuring pin, the receiving surface is made of brass and the rest of the body is nickel-plated. This has the advantage that external interference has a very small effect on the measurement result. In addition to the standard MS version, high-temperature versions made of stainless steel are also available.
