Temperature sensors /Thermocouple

Thermocouple
Angled screw

Series GF-7020/W

General

Gräff temperature sensors of the GF-7020/W series are particularly suitable for use in temperature measurement on tools, heating blocks, thermo blocks, 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 variable screw connection offers the advantage that sensors can be inserted and replaced very easily and quickly by attaching a sensor hole with a surface thread. 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. All sensors of this series are already equipped with an anti-kink spring for line protection. By means of spring pressure, the measuring system is always fixed with suitable contact pressure in your sensor bore in order to record the best and very accurate process temperatures here!
