Radar - for bulk level cement measurement
A radar sensor has been developed specifically for level measurement of bulk materials. The great advantage of radar as a physical measuring principle is that it is scarcely affected by process parameters like dust or airflow. Nor are the radar signals sensitive to high temperatures, so installation in clinker coolers is also a possibility. In addition to this, this radar sensor is 1 000 times more sensitive than conventional equipment.
The particular physical properties of non-contact radar technology make it suitable for many measuring tasks within the cement production process.
- Level measurement of bulk materials in silos and storage halls, and also in crushers or clinker coolers, represents one of the challenges of the cement production process.
- High dust concentrations, extreme temperatures, severely abrasive stresses and difficult installation conditions make the measurements more difficult.
- Non-contact radar technology makes it suitable for many measuring tasks within the cement production process.
