Measuring potassium content for the potash industry

The detection of the K-40 requires an extremely sensitive and stable measurement system, which must be capable of suppressing the inherent background radiation in order to obtain an optimal signal-to-noise ratio. Through the detection of K-40, the concentration of K2O or KCl can be measured. Berthold has the perfect solution for this challenging task, providing accurate potassium measurements with the potassium analyzer LB 474. The system is noncontacting, which virtually eliminates maintenance and costly downtime. Highly sensitive, stable and rugged detectors are fundamental in achieving a precise and accurate measurement.

Article „Radiometric Gauges in the Potash industry”

In the potash industry, it is important to use robust and reliable measuring devices. This article published in the journal World Fertilizer September 2020 (page 50-54) presents the advantages of non-contacting radiometric gauges in the potash industry and the application fields where those gauges significantly contribute to process optimization.

Different detector types

The LB 474 potassium analyser uses three different types of detectors depending on the process conditions and the mechanical arrangement.
When maximum sensitivity is required, Berthold’s SuperSENS detector is used. Due to its compact design this is the ideal solution for maximum sensitivity.
For surface mounted applications on vessels or belts typically maximum sensitivity combined with high stability is required. Here Berthold’s dedicated potassium detector with its large 125/50 CrystalSENS is the preferred solution.
For tanks with suspension, the better solution is an immersion tube installed in the  center of the tank. In the immersion tube you can either install the immersion type of the SuperSENS or, if immersion tubes with smaller diameters are required, Berthold‘s 50/50 CrystalSENS is the right choice. The signal-to-noise ratio of this arrangement is unrivalled and therefore offers unmatched accuracy and measurement stability.
