3.2 Principle of operation
CNCR-230 is a radar sensor for continuous level measurement. It is suitable for liquids and
solids in practically all industries.
The instrument emits a continuous, frequency-modulated radar signal from its antenna. The
emittedsignalisreectedbythematerialandreceivedbytheantennaasanechowithmodied
frequency. The frequency change is proportional to the distance to the material.

4.1 General instructions
The instrument is suitable for standard and extended ambient conditions acc. to DIN/EN/IEC/ANSI/
ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors.
Protect your instrument against moisture ingress through the following measures:
• Use a suitable connection cable
•Tightenthecableglandorplugconnectorrmly
• Face the connection cable or conduit entry downward, never upward
This applies mainly to outdoor installations, in areas where high humidity is expected (e.g. through
cleaning processes) and on cooled or heated vessels.

4.2 Mounting instructions
The radar emits pulses of electromagmetic waves which are polarized. By adjusting the rotation of
the instrument the polarization can be changed to reduce false echoes.
The narrow portion of the radar signal is in the middle of the conduit entry on the instrument. This
should be pointed towards the center of the vessel or any obstacle that may cause any unwanted
reectionstominimizefalseechos,forexample,thesidewallorvesselstructure.
Fig. 4: Polarization Position
1. Cable conduit entry/vent
The lower side of the radar antenna is the beginning of the measuring range. It is at the same time
the reference plane for the min./max. adjustment, see following diagram:
When mounting the sensor, keep a distanceofatleast200mm(7.874in)from the vessel wall. If the
sensor is installed in the center of a round top vessel, multiple echoes can arise. However, these can
be suppressed by a false signal suppression (see chapter “Set up”).

In vessels with cone bottoms, the sensor can be mounted in the center of the vessel
to measure material down to the outlet.

Fig.6:Mountingtheradarsensoronroundvesseltops
If you cannot maintain this distance, you should carry out a false signal suppression during initial
setup. This applies particularly if buildup on the vessel wall is expected. If this is the case, we
recommend repeating the false signal suppression later with the additional buildup.

When using a threaded coupling, the antenna end should protrude at least 5 mm (0.2 in) out
of the socket.

stand pipes longer than the antenna. The pipe end should be smooth, burr-free, and the end
rounded.
Recommended values for socket or stand pipe lengths and heights are in the following table.
The values come from typical applications.

100 mm 4” ≤400mm ≤15.8in
150 mm 6” ≤600mm ≤23.6in
Note:
The sensor should be mounted in a location where the radar signal is not interfered with by
structure,suchasladders,bracesorllstream.
Make sure when planning the installation there is a clear, unobstructed view to the material to
be measured. After installation a false signal suppression should be carried out to minimize
anyreectionsfromthemountornearbystructure.
5 Connecting to power supply
5.1 Preparing the connection
•Carryoutelectricalconnectionbytrained,qualiedpersonnelauthorizedbytheplantoperator
• If overvoltage surges are expected, overvoltage arresters should be installed
Warning:
Only connect or disconnect in de-energized state.
Note:
Power the instrument via an energy-limited circuit (power max. 100 W) according to IEC 61010-1, e.g.
• Class 2 power supply unit (acc. to UL1310)
• SELV power supply unit (safety extra-low voltage) with suitable internal or external limitation
of the output current

checkthecablediameterversusthecableglandbeforewiringforpropert.
The instrument is connected with standard two-wire cable. If electromagnetic interference is
expected which is above the test values of EN 61326-1 for industrial areas, shielded cable
should be used.
