Functional Principle, Technical Data
2.1
Area of Application
The capaNCDT CST6110 is a capacitive measuring system for non-contact rotation speed measurement of conductive measurement
objects such as metals and non-conductive objects such as ceramics or plastics.
2.2
Measuring Principle
The sensor reacts to approach or removal (depending on the initial state) of materials. The capacitive measuring principle is based
on load shifts in the sensor. This change in capacitance is detected and analyzed by the controller. The rotational speed of measuring
objects made of non-conductive materials is also measured. This requires a shorter distance between sensor and measuring object
than with electrically conductive measuring objects.
2.3
Structure of the Complete Measuring System
The non-contact single channel measuring system consists of:
- Sensor with sensor cable
- Controller (installed in a compact aluminum housing)
- Power supply and signal cable SCAC3/6, see Chap.
Individual measuring system components can be replaced without limitations of their functionality.
