Point level detection – hygienic/industrial
To ensure a fully functional adaptive trigger, the
following conditions have to be fulfilled:
The sensor has to be in air during startup.
„„
The input signal has to be steady.
„„
The difference between the value for untriggered
„„
and the value for triggered must be more than
3 %.
If a new medium with a DC value lower than
„„
the previously configured DC value has to be
detected, the sensor tip should be cleaned before
the new medium is filled in the tank or pipe.
14.2 Window trigger
The window trigger is used to cause a sensor switch to react within a specific range, for example, in order
to isolate a specific medium. The switching window can be configured within a range from 0 ... 100 %. The
window trigger is recommended for detecting and separating different layers, for example oil from water or
foam from beer.

Steady detection
Configuration example for a vessel that can be
filled with either a good conductive adhesive
medium (e.g. fruit preparation) or with an oily
medium (e.g. chocolate mix).
Switch windows I and II in this example are set to
achieve the following goals:
to detect the fruit preparation (1)
„„
to exclude adhesion from fruit preparation (2)
„„
to identify the chocolate mixture (3)
„„
