Description
The level electrode operation is based on the conductive measuring principle. The NRG ...-4 is
designed for signalling the max. liquid level in electrically conductive liquids.
■
One liquid level with one switchpoint
The NRG ...-4 is to be used in conjunction with the switching controller NRS -4 and further
system components.
NRG ...-4 in conjunction with the associated control equipment constitutes a water level limiter
with periodic self-testing routine (SMART function) in accordance with TRD 604, sheet  and  and EN
regulations. The level data are transferred from the electrode NRG ...-4 to the control equipment via
a CAN bus using the CANopen protocol.
