Temperature sensors /Thermocouple

Thermocouple
Surface sensor non-contact

Series GF-7044

General

Gräff temperature sensors of the GF-7044 series are particularly suitable for use in temperature measurement on pull-off rollers, embossing rollers or surfaces, etc. from the plastics or metal industry. This version records temperatures without contact, quickly and very precisely. In contrast to infrared measurement, no special surfaces need to be created here. Like all Gräff sensors, these sensors are also manufactured exclusively with selected materials. The special dimensions and materials of the measuring tip enable the temperature to be recorded without any interference. Due to a free selection of the sensor diameter and the sensor length, there are hardly any limits to this version GF-7044.
It goes without saying that we only use thermo-cables instead of compensating cables for this version. A corresponding cable kink protection completes this product.
