Resistance thermometer
Surface sensor with ring shape

Series GF-7129

General

Gräff temperature sensors of the GF-7029 series are particularly suitable for use in temperature measurement on
tools, engines, cooling systems, heating blocks, thermos 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. Due to the combination of high-quality materials, there are no limits to this series. In addition, the design as a round sensor offers the advantage that the temperature on surfaces can be recorded simply but precisely by attaching a standard M6 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 with a diameter of 16 mm, all customer-specific diameters can be implemented. The slightly angled cable outlet of 5° enables the sensor to be placed flat, even where little space is required.
