Textile Industry > Thread quality control

To assure the uniform quality of textile threads of natural origin, it is usually essential to perform a check for inadmissibly large geometric deviations of the threads, like, for example, thickening or knots. Suitable for this type of check is a capacitive measuring system.

The capacitor of such a system can be structured as follows:

Plates made of Al2O3 ceramic coated with electrodes are used, for example, as the wear-resistant dielectric. These electrodes are contacted with the periphery electronic equipment by means of electric conductors in the material. To avoid mechanical abrasion by the threads each running through two plates, the electrodes are protected with an abrasion-resistant layer of glass.

To realize such a component, for ceramic-metal composites, coating and joining processes that have proven effective for years are used and guarantee reliable functioning of the capacitor for many years.
