Temperature sensors /Thermocouple

Thermocouple
Surface sensor with
– cuboid

Series GF-7031/Q

General

Gräff temperature sensors of the GF-7031/Q series are particularly suitable for use in temperature measurement on tools, engines, cooling systems, heating blocks, thermoblocks, heating systems, 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 design as a cuboid sensor offers the advantage that the temperature on surfaces can be recorded simply but precisely by attaching a standard M4 bore. 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 version, there is the option of manufacturing customer-specific versions. Like all Gräff sensors, this version is also made of stainless steel 1.4571 as standard. A 70 mm anti-kink spring is installed to protect the cable.
