Features of the UM-X measurement analysis system

The UM-X measurement analysis system is a standalone display for continuous
filling level sensors. It is powered directly by the mains voltage and provides the
power supply for the filling level sensor at the same time. The filling level can be
displayed as analogue and digital on the graphic display.

The UM-X measurement analysis system also provides five potential-free change
over contacts. The switching points of the five relays are adjusted via the display
using 4 buttons and the statuses of the relays can be checked using the display.

The UM-X measurement analysis system

• can be used for all filling level sensors with a 4-20 mA interface.

• can be supplied with ATEX approval (intrinsically safe electric circuit).

• can be supplied as approved overfill prevention.

• shows the filling level as digital and analogue display.

• has five potential-free change over contacts as binary outputs.

• provides simple, menu-driven operation using a graphical display.

• is installed in splash-proof case.

There are 4 equipment versions of the UM-X measurement analysis system:
