1.4 Intended Use
- The capaNCDT 62x8 measuring system is designed for use in industrial areas. It is used for
displacement, distance, thickness and movement measurement
position measuring of parts or machine components
- The system must only be operated within the limits specified in the technical data, see 2.3.
The system must be used in such a way that no persons are endangered or machines and other mate-
rial goods are damaged in the event of malfunction or total failure of the system.
Take additional precautions for safety and damage prevention in case of safety-related applications.
1.5 Proper Environment

• Sensor -50 ... +200 °C (-58 to +392 °F)
• Sensor cable: -50... +200 C (-58 to +392 °F) (CCmx and CCmx/90)
-20 ... +80 °C (-58 to +392 °F) (CCgx and CCgx/90 - perma-
nently)
-20 ... +100 °C (-58 to +392 °F) (CCgx and CCgx/90 - 10,000 h)
• Controller: +10 ... +60 °C (+50 to +140 °F)
Storage:

Functional Principle, Technical Data
capaNCDT 6228 / 6238
2. Functional Principle, Technical Data
2.1 Measuring Principle
The principle of capacitive distance measurement with the capaNCDT system is based on the principle of the
parallel plate capacitor. For conductive targets, the sensor and the target opposite form the two plate elec-
trodes.
If a constant AC current flows through the sensor capacitor, the amplitude of the AC voltage at the sensor is
proportional to the distance between the capacitor electrodes. The AC voltage is demodulated, amplified and
output as an analog signal.
The capaNCDT system evaluates the reactance XCof the plate capacitor which changes strictly in proportion
to the distance.

iA small target and bent (uneven) surfaces cause a non-linear characteristic.
This theoretical relationship is realized almost ideally in
practice by designing the sensors as guard ring capaci-
tors.
The linear characteristic of the measuring signal is
achieved for electrically conductive target materials
(metals) without any additional electronic linearization.
Slight changes in the conductivity or magnetic proper-
ties do not affect the sensitivity or linearity.
