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 6110 / 6120 contains a voltage processing, oscillator, integrated preamplifier, demodulator 2
as well as an output level.
The voltage processing produces all necessary internal voltages from the power supply. The oscillator sup-
plies the sensor with frequency and amplitude-stabilized alternating voltage. The frequency is 31 kHz. The
internal preamplifier generates the distance-dependent measuring signal and amplifies it. Demodulator and
output level convert the measuring signal into a standard voltage signal 3.
The output voltage can reach up to a maximum of 13 VDC when sensor is disconnected or measurement is
exceeded.

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 flush.
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.

4.2.2 Circumferential Clamping, Cylindric Sensors
This sensor mounting option offers maximum reliability because the sensor is clamped around its cylindrical
housing. It is absolutely necessary in difficult installation environments, for example on machines, production
plants et cetera.
