3.2 Principle of operation
CNCR-110 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
emittedsignalisreectedbythematerialandreceivedbytheantennaasanechowitha
modiedfrequency.Thefrequencychangeisproportionaltothedistancetothematerial.

4.2 Mounting
For a rigid mount, a mounting bracket with opening for thread G1 is recommended. The sensor is
mounted in the bracket using the supplied G1 plastic nut. Take note of Figure 4 for the recommended
minimum distance to the vessel wall.

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.
4.3 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 printed label on the instrument. This
should be pointed towards the center of the vessel or any obstacle that may cause and unwanted
reectionstominimizefalseechos,forexample,thesidewallorvesselstructure.

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 a round vessel top, 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.
Fig. 5: Mounting the radar sensor on round vessel tops
In vessels with cone bottoms, the sensor can be mounted in the center of the vessel to measure
material down to the outlet.

For socket or stand pipe mount, the pipe should be as short as possible and its bottom end rounded
toreducefalsereectionsfromtheendofthepipe.
When using a threaded coupling, the antenna end should protrude at least 5 mm (0.2 in) out of the
coupling.
Ifthereectivepropertiesofthematerialaregood,youcanmounttheCNCR-110onsocketsor
stand pipes longer than the antenna. The pipe end should be smooth, burr-free and the end
rounded.

Socket diameter d Socket length h
40 mm 1½” ≤150mm ≤5.9in

80 mm 3” ≤300mm ≤11.8in
100 mm 4” ≤400mm ≤15.8in
150 mm 6” ≤600mm ≤23.6in
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.
Note:
When mounting on longer sockets or stand pipes, we recommend carrying out a false signal
suppression after install (see chapter 6.3 “Parameter adjustment”).
Recommended values for socket or stand pipe lengths and heights are in the following table. The
values come from typical applications.

5.1 Preparing the connection
•Electricalconnectionshouldbecompletedbytrained,qualiedpersonnel
• Authorized by the plant operator
• 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)
acc. 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
