The experts for measurement solutions

Besides our nucleonic level measurement systems we provide non-contacting radiometric belt weighers and gamma densitometers for the concentration measurement of slurries, e.g. in tunnel boring or dredging. In addition Berthold supplies non-contacting online moisture analyzers based on microwave technology. Mounted directly at the conveyor belt, chute or bunker they provide an accurate and representative moisture reading and valuable real-time information on the on-going process.

Level measurement for cement clinker coolers

Cement Clinker cooler with measurement system

Detector for the toughest work environments in non-hazardous areas

In cement production, the heart of the system is the rotary kiln, and the corresponding cooling system that follows it. The efficient operation of these two systems together is critical in maintaining efficiency and profitability in the manufacturing process. With operating temperatures in excess of 1000°C, the measurement of important parameters, such as the level of clinker on the cooling grates, is fraught with problems. Traditional, intrusive level measurement technologies simply cannot last in such a harsh environment.

To optimize cost savings, the airflow must be regulated to the proper amount for the mass of the clinker present on the cooler grates. This requires an accurate level measurement of the clinker. Berthold's non-contacting and non-intrusive radiometric level measurement technology provides a means of making an accurate and reliable clinker level measurement while operating outside this extreme high temperature environment. The high degree of accuracy, stability and repeatability insures high production rates, optimal efficiencies and superior product quality.

Glass melt furnaces offer one of the most challenging environments for any type of industrial process measurement and control. Extreme process conditions, such as high temperatures and dense refractory material, require an extremely robust yet reliable and accurate level measurement. Especially an efficient and high quality glass production is in need of a reliable and safe glass level measurement just after the glass leaves the main feeder channel.

Radiometric based level measurement systems with the use of Co-60 isotope, proper alignment, and an effective calibration procedure offer best in class measurement results for the glass industry to maximize safety, reliability, and throughput.
