properties of the displacement sensor and the cable. They form
part of a harmonised electrical oscillating circuit that is fed by
the driver. The electrical harmonisation is part of the system
production process. Within the given tolerances, the actual sys-
tem length may be greater than the nominal system length.
With this adapter, the driver (oscillator/demodulator) can either
be mounted on a hat-rail or screw mounted onto a firm and
even surface. In addition, it serves as an electrical insulation
between driver and mounting surface.
Refers to the ceramic front part of the displacement sensor
The term displacement sensor includes the components of sen-
sor tip with measuring coil, threaded sleeve and integrated
extension cable. The length of the displacement sensor is
defined as the distance from the sensor tip to the end of the
plug connector attached to the extended integrated extension
cable.
The measuring surface whose distance to the sensor tip is
being measured.
The material of which the measuring surface is composed.
