For trend analysis, the measured signal is also be displayed on a 41 segment bargraph. It's possible to scale the bargraph separately to the digital value. The indicator D122 is available in several housings.

Furthermore with alarm monitoring option the indicator has two intrinsically safe alarm outputs. These outputs change their state, when the measured value exceeds his alarm limits. It’s possible to choose open-circuit or closed-circuit connection.

Additional the alarm limits appear graphically on a second bargraph. On one look you’re sure that the measured value is in its limits.
