2. System Description
2.1 Area of Application
The eddyNCDT 3010 non-contact, compact displacement measuring systems are designed for industrial
applications in production plants, for machine supervision and for measuring and testing in in-process
quality assurance.
2.2 Measuring Principle
The eddyNCDT 3010 (Non-Contacting Displacement Transducers) displacement measuring system operates
without contact using eddy current technology. It is used for making measurements on targets made of either
ferromagnetic or non-ferromagnetic electrically conductive materials.
High-frequency alternating current flows through a coil cast in a sensor casing. The electromagnetic coil
field induces eddy currents in the conductive target thus changing the ac resistance of the coil. This change
in impedance is interpreted by demodulation electronics which generate an electrical signal proportional to
the distance of the target from the sensor.
A patented electronic compensation technique reduces temperature-dependent measuring errors to a mini-
mum.

4.1.2 Sensor Cable
The special coaxial sensor cable is available in two connection versions:
- Connection already integrated in the sensor, see Fig. 5: Type U05, U1, S1, or
- plug-in connection cable, see Fig. 6.
The standard cable (C3) has a length of 3 m.
Available as an option: 6 m cable (C6), see Chap. A 2.

Connect the cable with the bulge at the controller.
The cables of one type are tuned to the same capacitance at the factory. This may result in deviations in
length of +15 % in relation to the nominal length.
i Do not shorten the tuned cables, because this changes the capacity and the adjustment of the measu- ring system.

The oscillator and demodulator electronics are on one board.
- The oscillator electronics feed the sensor with a frequency and amplitude stable ac voltage.
- The demodulator electronics demodulates, linearizes and amplifies the distance dependent measuring
signal.
The controller is already tuned to the delivered sensor with sensor cable at the factory.

4.2 Synchronization in Multichannel Systems
Several measuring systems in the eddyNCDT 3010 series can be operated simultaneously as multichannel
systems.
Synchronization of the measuring systems avoid interference between the sensors.
Plug the SC30 synchronization cable, available as an accessory, see Chap. A 1, in the SYN OUT socket
(synchronization output) in controller 1.
Plug the other end on the cable into the SYN IN socket (synchronization input) in controller 2.
The oscillator in controller 2 switches automatically to synchronization mode, that is it acts as slave to the
master oscillator in the controller 1. Nearby mounted sensors no longer interact therewith.
Synchronize several measuring systems with the SC30 cable if necessary.

4.3 System Adjustment
Calibrate the measuring systems of the eddyNCDT series 3010 for his particular application before
measuring, see Chap. 5.4.
Use, if possible
- the actual sensor mounting and
- the actual target
iIf you cannot use the actual target, simulate the measuring environment as accurately as possible.
4.4 Sensor Mounting
Eddy current displacement sensors may be influenced by an adjacent metallic attachment.
Prefer the following sensor mountings according to the used sensor type
- unshielded sensors: Standard mounting
- shielded sensors: Flush mounting
4.4.1 Standard Mounting
The sensors protrude beyond the metal support.
Sensors with thread, see Fig. 9, see Fig. 10
Push the sensor through the hole in the sensor support.
Screw the sensor tightening the mounting nuts on the thread protruding from the support on both sides.
Tighten carefully to avoid damaging the sensors, especially the smaller ones.
