Installation and Assembly
No sharp or heavy objects should be allowed to affect
the cable sheath of the sensor cable, the supply cable
and the output cable.
i
A damaged cable cannot be repaired. Tension on
the cable is not permitted!!
Sensor
Unshielded sensors
- Type designation: ES-Ux
- Construction: The sensor cap with
encapsulated coil consists of elec-
trically non-conducting materials.
i
In 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.
Shielded sensors
- Type designation: ES-Sx
- Construction: The sensor en-
closed up to its front face with
a steel housing with a mount-
ing thread. With it the sensor
is shielded from interference
through radially near located
metal parts.
Start of Measuring Range
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.

Measuring range (MR)
Start of measuring range (SMR), the minimum distance
between sensor face and target
Eddy current displacement sensors can be affected in
their measurement properties by a metallic holder. De-
pending on the sensor type, the following sensor mount-
ing should be preferred:
- unshielded sensors: Standard mounting
- shielded sensors: Flush mounting
