Presentation

For displacement and distance measurements at ambient temperatures up to +800 °C, Micro-Epsilon now offers the robust, capacitive capaNCDT 6228 sensor system. Its high temperature stability and exceptionally high linearity enables precise results even in challenging ambient conditions.

The new capacitive sensor system capaNCDT 6228 consists of the capacitive high temperature sensors capaNCDT CSE/HT and the capaNCDT 6228 controller. The sensor system is designed for high temperature applications up to +800 °C. It is used, among other things, to measure the thickness of glowing brake discs and to monitor the level of float glass. Up to four sensors can be connected to the high-performance controller simultaneously.

The available sensors cover measuring ranges from 1 mm up to 20 mm. A high-temperature sensor cable compensates for interference from electric or magnetic fields. Furthermore, the measured data is output both analog and digital via modern interfaces such as Ethernet and EtherCAT.
