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.

2.2.1 Sensors
For this measurement system, several sensors can be used.
In order to obtain accurate measuring results, keep the surface of the sensor clean and free from dam-
age.
The capacitive measuring process is area-related. A minimum area (see table) is required depending on the
sensor model and measuring range. In the case of insulators the dielectric constant and the target thickness
also play an important role.

2.2.3 Controller
The capaNCDT 6222 Multi-channel measuring system consists of a basic module DT62xx and one up to four
demodulator modules DL62xx, according to requirements. The components are stored in aluminum hous-
ings.

Page 16
Functional Principle, Technical Data
capaNCDT 6222
Basic module DT6222
The basic module DL62xx consists of the units voltage conditioning, oscillator and digital unit.
The voltage conditioning generates all required internal voltages from the supply voltage, both for the basic
module as well as the connected demodulator modules. The oscillator supplies the demodulator modules
with constant frequency and amplitude-stable alternating current. The frequency is 62 kHz. The digital unit
controls the A/D converter of the demodulator modules and measures the actual measuring values. The mea-
suring values can be read out via the Ethernet interface in digital form, see Chap. 6.
Demodulator module DL6222
The demodulator module DL62xx consists of an internal preamplifier, demodulator, output stage and A/D
converter. The internal preamplifier generates the distance dependent measuring signal and amplifies it. De-
modulator and output stage convert the measuring signal in a standardized voltage and current signal. The
measuring values can be processed digitally with the help of the A/D converter.
The trim potentiometer zero allows a special zero adjustment of the analog output signals, see Fig. 3.
iOutput voltage can achieve up to 15 VDC, if the sensor is disconnected respectively exceedance of measuring range.

4. Installation and Assembly
4.1 Precautionary Measures
No sharp-edged or heavy objects may get into contact with the sensor cable sheath.
Protect the cable against pressure loads in pressurised rooms.
Avoid kinks in any case.
Check the connections for tight fit.
iA damaged cable cannot be repaired.
4.2 Sensor
The sensors may be mounted free-standing or ush.
When assembling, make sure that the polished sensor surface is not scratched.
4.2.1 Radial Point Clamping with Grub Screw, Cylindric Sensors
This simple type of fixture is only recommended for a force and vibration-free installation position. The grub
screw must be made of plastic so that it cannot damage or deform the sensor housing.
