Digital sensor technology for process analytical technology (PAT) - New strategies for maintenance

Increasing cost pressure continues to be a feature of the chemical industry. Nowadays, not only the cost of energy and raw materials are reducing the productivity of chemical plants, but most importantly labor costs and maintenance costs are having a considerable impact on competitiveness. In the context of worldwide competition, this means that it is more important than ever to ensure optimum product quality while maximizing productivity. At the same time, operational safety must be guaranteed. Similarly, effective processes require a high degree of automation. Elaborate measurement and control systems in conjunction with automated process management concepts support plant operators in achieving these objectives. Today, the use of process analytical measurement technology is a significant component of measurement and control technology in chemical plants as it also supplies data which are of utmost importance to product quality and productivity.

Analytical sensors in hygiene processes

The sensory mechanisms for hygienic applications in the food and pharmaceutical industry are currently in a major state of upheaval. While "good engineering practice" often sufficed in earlier years, this is simply not enough today. Headed by the pharmaceutical industry, which has to validate each of its processes individually, demands are being made to verify the hygienic properties of all the process components. Special attention is given to analytical measuring technology here (pH measurement, electrolytic conductivity, dissolved oxygen, optical turbidity etc.) as these parameters are "quality parameters" which are particularly important for controlling hygienic processes.

Container measurement stations - customized system solutions for analytical technology

The demands on analytical measurement technology continue to increase in all areas of everyday industrial activity and in the public sector. There are two central issues here. First and foremost, there is the issue of environmental protection; we all need clean water and clean air to breathe. Secondly, our highly developed industrial landscape depends on reliable analytical technology; the focus here is on product quality and equally on the fulfillment of a range of obligations concerning environmental protection.

In-situ measuring systems for nutrients and analyzers for sum parameters

In today's world, standards for water quality are constantly increasing. For this reason, various monitoring stages are being fitted with online measuring devices more and more often which results in a far greater frequency of analysis in quality monitoring compared to lab analysis. With lab analysis, the sometimes long time delay is a major obstacle in achieving correct and good quality assurance.

Foolproof operation and measurement

The success story of the innovative Memosens sensor technology and the new Liquiline transmitter stems from the insistent demands of customers for measuring points which are not sensitive to rain, snow or moisture and for sensors which can be cleaned, calibrated and regenerated in comfortable conditions. In particular, there was a demand for easy and intuitive operation, a high degree of flexibility of the measuring point in terms of maintenance and service in addition to an ability to adapt easily to the widest range of applications.
