Level Monitors
Level Monitor Type NS43V
Switchgear-mount Housing
The NS unit protects aggregates
and plants against dry running,
overow, leakage damages and
unnecessary loss of liquids.
It controls and monitors levels of
liquids in waste-water, pools, sh
farms and whereever a certain
level should be maintained or
dosed.
Depending on the application and
the set program, it controls the
level between 2 or 3 electrodes
by means of opening or closing
dose or drain of a container.
The top and the lowest electrode
protect from overow or running
dry.
An electrolytic corrosion of the electrodes as well as
detonating gas production is excluded due to a AC
current measuring path.
The universal supply voltage AC/DC 24-240 V allows to
connect the relay to any common mains.The isolation
between electronics (= electrodes) and supply voltage
avoids malfunctions caused by potential spreading,
also at DC-supplys.

Technical Data
The NS level monitor is an elec-
tronic device for monitoring levels
of conductive liquids.
The monitoring of the levels is
eected vis electrodes, which
are dipped or set free according
to liquid level.
All conductive liquids can be
monitored, preferrably, however,
water, also of dierent degree of
hardness.
To adapt the relay to the conductivity of the liquid and to
the capacitance of (long) cables, the switching limit can
be adjusted app. 5 kΩ ... 250 kΩ. Thus it also is possible
to tell between the liquid and foam over the liquid.
