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. In the application range of the machine monitoring, this makes it
possible to record the status of rotating shafts.
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.
