Sensor system for monitoring the planar tool flange contact on the basis of ceramic resonators and circular waveguide structures

The proposed sensor system based on ceramic resonators and circular waveguide structures offers a novel solution for controlling the quality of tool clamping in a tool-receiving socket interface. Compared to current solutions this sensor system enables both an easy, cost-effective production and a high-resolution passive distance measurement on a rotating system component. The basic element of the monitoring system are standard bores in combination with industrial ceramic pins as well as standard potting compound, through which an electromagnetic signal is transferred to the measurement location.
