In plants in the food and beverages industry, be it in dairies, breweries or in the production of juices, the standards for cleanliness and hygiene are becoming tighter and tighter. Reliable measuring technology is demanded in particular for the cleaning procedures in the plants (CIP = Clean in Place): you have to guarantee that the cleaning liquids flow through the entire plant for a fixed period at a fixed temperature.

For this purpose, Endress+Hauser's conductivity sensors constantly monitor the concentration of the solutions in the return line and the temperature is measured by integrated sensors.

In the pharmaceutical industry, particularly high demands are made regarding the hygiene and cleanability of the plant units.

Endress+Hauser offers measuring technology for monitoring WFI water and cleaning water. One of the most important demands in pharmaceutical operations is the traceability of the production and the measuring devices as well as the traceability of the calibrations. In addition, calibration should be possible without having to interrupt the sterile process. Endress+Hauser offers the Concal reference system for pure and ultrapure water.

The inductive sensor Indumax P CLS50 is used for determining the concentration of acids, alkalis and salts in the chemical industry. It can be supplied with a shaft made of PEEK or the highly resistant fluoropolymer PFA.

Depending on the preconditioning, the Condumax W CLS12, CLS13 or CLS15 sensors are suitable for monitoring the water quality for the boiler feedwater circuits in power stations. The former two sensors can be operated with pressures up to 40 bar. 

The Condumax W CLS21 sensor is provided with the Liquisys M CLM253 transmitter for on-line monitoring of the residual conductivity (according to the German TVO Drinking Water Directive) in drinking water or in sewage treatment plant outlets. In this way, the owner/operator achieves water quality monitoring with zero delay.

In the inlet of sewage treatment plants, the inductive sensor Indumax P CLS50 is your best choice as it is insensitive to contamination.
