Description
The level electrode NRG ...-40 works according to the conductivity measurement principle.
The NRG ...-40 is designed for use in conductive liquids to detect the minimum liquid level:
■
One level with
one switchpoint.
The NRG ...-40 is used in combination with switching controller NRS -40 or NRS -40. or further
system components. NRG ...-40 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 ...-40 to the
control unit via a CAN bus using the CANopen protocol.
