Turning online water analysis into child’s play

Designing and developing a state-of-the-art water analyser presents many tough obstacles, one of them being that the instrument should be not only precise, but easy to use.  In the picture you can see Supriya Jamwal, Seibold Wasser Analysatorenfabrik’s Business Development and Marketing Manager, putting the final touches to her Lego model of Seibold’s top-of the-range ‘Wilhelm Kienzl’ Analyser for monitoring of arsenic in water.

For any instrument to deliver continuous, reliable and accurate data ..it is crucial that its operation should be simple. Simple machines to carry out complex measurements is an ideal that the development team at Seibold strive for.

The analyser is simple because it has only three parts: electronics, pumps and the photometer. The electronic aspect is failsafe, standard electronics to deliver information internally and externally. Internally the electronics drives the pumps, reads the photometer and calculates measurement results; externally, it delivers information to the central PLC. The pumps are peristaltic hose pumps. Every liquid has its own dedicated stepper motor pump, eliminating the need for multi-folds or switches which increase the complexity of an instrument. Finally, the analyser includes a glass photometer where LED at specific wavelength reads the absorption of light beam caused by the relationship between the dye and the element we want to measure.
