Hengesbach Level Module NC1 Series

The NC1 is a self-adjusting level module designed for installation into the head of a conductive measuring sensor. The NC1 is used for product and foam detection. A low- and high-resistance switch output enables "full" and "empty" messages to be sent for liquids with a high or low conductivity. It can even be used for foaming liquids. Intricate adjustments of the NC1 and adaptation to the various product conductivities, tank geometries and electrode lengths are no longer required. The NC1 finds its own switch points, using innovative methods. In addition, the NC1 is protected against reverse polarity of the supply voltage and against output overload. The outputs are low-active, so that the output signal will be triggered even if there is a drop in voltage or if the wire breaks. The operating mode, i.e. high-level or low-level, is determined via a link plug.
