Continental launches the new Conti Load Sense monitoring systemEngineering360 News Desk | March 16, 2022
Continental is taking another step toward predictive maintenance and condition monitoring in conveyor belt technology by launching the new Conti Load Sense monitoring system. The system is based on 2D radar technology and measures the material flow on the conveyor belt. It can be used in almost all industries where conveyor belt systems are in operation — for example as it is currently the case in gravel extraction.
At the gravel plant of August Oppermann Kiesgewinnungs-und Vertriebs-GmbH in Northeim, Germany, the extraction of material depends on the individual loading of the belt by each worker. Thanks to the volume measurement of the Conti Load Sense radar-based monitoring system, gravel plant operators are now able to use the so-called deep grab even more efficiently. This increases the output by up to 100,000 tons per year. Conti Load Sense can also be connected to the Conti Cloud. This means that the recorded data can be processed in a visually appealing way for the end customer via a web service or the Conti+ online service portal and the associated Conti+ app.
The gravel industry — like many others — faces the challenge of extracting and processing material more efficiently, reliably and in a more environmentally friendly manner. This is where not only Continental's high-quality and robust conveyor belts come into play, but also associated equipment and service tools — above all, digital components that comprehensively monitor the conveyor process and the material. For years, the technology company headquartered in Hanover, Germany, has been focusing on condition monitoring and predictive maintenance as important topics for the future. With the Conti Load Sense, which is based on radar sensors developed by Continental and used millions of times in cars and industrial vehicles, the company is now expanding its portfolio in this area.
Using 2D radar (radio detection and ranging) and ultrasonic technologies, the system scans the material and conveyor belt from different angles to determine the position of the load and the belt. This calculates the volume of material being conveyed.
"The risk of spilling material is determined by monitoring the belt edge position in relation to the profile of the material. The load center of gravity on the belt, as well as load distribution, is monitored 24/7 along the entire conveyor length," explained Patrick Raffler from Continental. "Data correlation is used to calculate volume flow, monitor overrun and belt skew. Belt speed is measured to track belt and load position along the entire length of the conveyor."
Based on this information, operators of stone, sand or gravel quarries can measurably increase their productivity. "The plants run more economically due to the automatic material detection, and the radar sensor reports deviations before losses occur, thus preventing follow-up costs," Raffler said.
Compared to previously used technologies such as laser or belt scale, the radar sensor requires less maintenance and is less sensitive to external influences like dust, rain and vibrations, which could negatively affect the measurement results.
In other applications, the new Continental system can be used in combination with other sensors for performance monitoring and thickness measurement, for example in the raw material conveying industry to measure bulk material volumes, check the durability of conveyor belts, forecast the service life of the conveyor belt, and save energy and costs. Conti Load Sense can also be easily integrated into existing plants.
