Product description
Observe the safety information in chapter "Safety"!
2.1
Basic function
The displacement sensor systems of the ds820 family are based on the non-contacting eddy-
current measurement process. The distance is measured between the tip of the displacement
sensor and an electrically conductive surface and sent via a proportional voltage signal to a
subsequent electronic monitor. This records the status of the rotating shafts as a part of surveil-
lance of the machine.
2.2
Components of the displacement sensor system
The eddy-current displacement sensor system consists of the components of displacement
sensor with an integrated cable, an optional separate extension cable and the driver (oscillator/
demodulator).
The name of a component is a combination of the series name ds822 ATEX and the component
designation (
mc
= complete system,
ds
= displacement sensor,
ec
= extension cable or
od
=
driver). Each series is available in system lengths of 5 m and 10 m.
