2. Functional Principle, Technical Data
2.1 Field of Application
The eddyNCDT 306x, 307x non-contact, compact displacement measuring systems are designed for industrial applications in produc-
tion plants, for machine supervision and for measuring and testing in in-process
quality assurance.
2.2 Measuring Principle
The eddyNCDT 306x, 307x (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.
A high frequency alternating current is passed through a coil installed in a sensor housing.
The electromagnetic coilfield 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 minimum.
2.3 Structure of the Complete Measuring System
The eddyNCDT 306x, 307x non-contact single channel displacement
measuring system consists of
- Sensor
- Sensor cable
- Connection cable
- Controller
iThe components are matched to one another. The allocation of the sensor and the controller is determined by the serial number.

4. Installation and Assembly
4.1 General
No sharp or heavy objects should be allowed to affect the cable sheath of the sensor cable, the supply cable and the output cable.
iA damaged cable cannot be repaired. Tension on the cable is not permitted!
4.1.1 Model
The eddyNCDT measuring system will be used with unshielded or shielded sensors.
Unshielded sensors
- Type designation: ES-Ux or ES-Ux-T
- Construction: The sensor cap with encapsulated coil consists of electrically
non-conducting materials.
iIn the radial direction metal parts in the vicinity may behave similar to the measuring object, rendering the measurement result inaccurate. Please
note this by selection of material for sensor mounting and their setup.
Fig. 2 Unshielded sensors with thread (left), without thread (right)
Shielded sensors
- Type designation: ES-Sx
- Construction: The sensor enclosed up to its front face with a steel housing
with a mounting thread. With it the sensor is shielded from interference
through radially near located metal parts.

Sensor Target
Measuring range (MR)
Fig. 4 Start of measuring range (SMR), the minimum distance between sensor face and target
For each sensor a minimum distance to the measuring object must be maintained.
This avoids a measurement uncertainty due to the sensor pressing on the measuring object and mechanical damage to the sensor/
target.
Eddy current displacement sensors can be affected in their measurement properties by a metallic holder.
Depending on the sensor type, the following sensor mounting should be preferred:
- unshielded sensors: Standard mounting
- shielded sensors: Flush mounting

4.2 Installation Scenario Sensor
4.2.1 Standard Mounting
The sensors protrude beyond the metal holder.
The installation scenario depicted is used for factory calibration of the
sensors at Micro-Epsilon.
The technical sensor data correspond to standard installation conditions.
If you want to achieve the values indicated in the data sheet, we recom-
mend to install the sensor in the same way as it was during calibration.
Sensors with a thread
Insert the sensor through the hole in the sensor holder.
Screw the sensor tight.
Turn the mounting nuts from the delivery on both sides on the thread protruding from the holder.
Tighten the mounting nuts carefully to avoid damage, particularly to smaller sensors.
iPrefer the standard mounting of the sensor, because the optimum measurement results can be achieved with this method. During calibration maintain the same relative position of the sensor to the holder as for the measurement!

During the factory-calibration of the sensors, the sensor front face is in a defined distance A from the mounting nut. Consider this
distance A for the application in order to achieve maximum linearity.
