3.2 Principle of operation
CNCR-210/220 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 emit-
tedsignalisreectedbythematerialandreceivedbytheantennaasanechowithamodied
frequency. The frequency change is proportional to the distance to the material.

4.2 Mounting
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.

4.1 General instructions
The instrument is suitable for standard and extended ambient conditions according 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 cable connection or conduit entry downward, never upward
This applies mainly to outdoor installations, in areas where high humidity is expected (e.g. through
cleaning processes) or on cooled or heated vessels.

In vessels with cone bottoms, the sensor can be mounted in the center of the vessel to mea-
sure material down to the outlet.
When mounting the sensor, distance it at least 200 mm (7.874 in) from the vessel wall. If the sensor
is installed in the center of dished or round vessel tops, multiple echoes can arise. However, these
can be suppressed by a false signal suppression (see chapter “Setup”).
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.

For socket or stand pipe mount, the pipe should be as short as possible and its bottom end
roundedtoreducefalsereectionsfromtheendofthepipe.
When using a threaded coupling, the antenna end should protrude at least 5 mm (0.2 in) out
of the coupling.

rounded.
Note:
When mounting on longer sockets, we recommend carrying out a false signal suppression after
install (see chapter “Parameter adjustment”).
Recommended values for socket or stand pipe lengths and heights are in the following table. The
values come from typical applications.

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.
Note:
If the temperatures are too high, the cable insulation can be damaged.
