Temperature transmitters – hot signals from multi-zone heated godet rolls 

 

The temperature modules transmit a rotating temperature signal to a stationary receiver component. Temperature transmitters are applied mainly for multi-zone heated godet rolls. They are proven to run in a harsh EMC environment. The transmitters work by contactless induction data transmission. Ageing, pollution and high outside temperatures don’t influence the precision of the temperature measurement.
 

UTR temperature transmission series are available as well as retrofit solutions, with guaranteed fit to existing temperature control systems.

Temperature controller – the 6 in 1 solution

 

Cleverly laid-out controllers achieve better results with multi-zone godets. Temperature controllers are developed to handle up to 6 individual positions or 6 heating zones with a single module. This controller is so smartly designed that it secures both production results and the investment in production equipment. Its amended electronics offer data which leads to the possibility of controlling bearing temperature. Any critical condition can be identified at an early stage and damage prevented. The lifespan of the godet rolls extends significantly.


All systems are able to communicate with each other using customized interfaces with various visualizations.

Roll temperature surface measurement tool – the outside view 

 

This device, protected by a silicon cover, is available for rolls with a diameter of 127 to 220mm. The magnetic fixed thermocouple Teflon cover protects the roll from mechanical damage. Axial distances of the thermocouples can be easily fixed with a screw. The roll temperature surface measurement tool is for godets with up to 4 individual measuring points.
