3.2 Principle of operation
CNCR-190 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
emitted signal is reflected by the material and received by the antenna as an echo with a modified
frequency. The frequency change is proportional to the distance to the material.
3.3 Adjustment
Devices with integrated Bluetooth module can be adjusted wirelessly via software adjustment tools:
• Smartphone/tablet (iOS or Android operating system)
• PC/notebook with Bluetooth USB adapter (Windows operating system)
