Process Instrumentation Range Measuring Technology for Hygienic Systems and Processes

Editor: Ahlam Rais

Innovations and fast development characterise the production processes in the beverages and food industries as well as in the biotechnology and pharmaceutical industries. The production processes in these industries are particularly demanding. Specific product properties need to comply with special hygienic requirements.

Stringent international directives such as Ped, Atex, Sil as well as standards stipulated by, for example, EHEDG, FDA and 3-A Sanitary Standards specify the requirements and application possibilities of process instrumentation equipment. Compliance with all these standards requires partners who are at home in the industry of their customers, who can offer a standardised product range, and who lead the way to the future of technology with innovative concepts and products. Afriso taps its comprehensive know-how and expertise in the industry to make its customers' processes simpler, safer and more competitive.

The company’s components and solutions are adapted to suit specific production processes and comply with the pertinent hygienic regulations and recommendations to meet stringent requirements. The robust measuring instruments deliver reliable measurement results, and monitor and control processes from simple to highly complex. Sophisticated kit systems and innovative ideas such as the seal-free design of diaphragm seals, pressure transmitters and thermometers help in the continuous optimisation of production facilities, states the firm.

As a full-line supplier with a complete portfolio in the areas of pressure, temperature and level measurement technology, the company offers a comprehensive, high-quality product range from a single source. The range extends from pressure gauges, chemical seals and pressure transducers to a large number of electronic and mechanical temperature measuring devices and control units as well as level indicators, which, depending on the application, are based on a wide variety of measuring principles. The following measure ranges are covered: pressure from 0/2.5 mbar bis 0/4,000 bar, temperature from -50 °C to +1,100 °C and level from 0/20 cm to 0/250 m; almost all parameters such as ranges, geometry, colour, connection can be specified according to customer requirements.

Specialist Book „Heat Transfer Technique“The comprehensive standard work „Heat Transfer Technique“ offers not only a detailed and well-founded presentation of the basics of heat transfer technique, but also shows the latest state of the art and the latest regulations in the use of organic fluids. Thematically, the book is rounded off with an overview of property data of organic heat transfer fluids as well as many use cases from practical experience.

In the adaptation of these peripheral system components, the stringent directive and standards are always in focus, so that a hygienic design of machines and systems is supported in an optimum manner. The firm supports compliance with GMP (Good Manufacturing Practices) required for the production of pharmaceuticals, food and animal feed, for example, by continuous quality assurance measures, such as a constant review of the production processes. The ISO 9001-compliant quality management system as well as certification according to the environmental standard DIN EN ISO 14001 serves as the basis for efficient GMP compliance. Ever since the early 1990s, the company has focused on these topics to ensure compliance with production process specifications and to lay the foundation for the protection of health and environment.

The materials used in the firm’s hygienic measuring systems meet FDA requirements for contact with food and drugs as per CFR (Code of Federal Regulations), part 21, adds the company. These materials comprise metals as well as elastomers for seals or oils for transmission in chemical seals. The EHEDG recommendations are also taken into account in the design of hygienic measuring instruments.

The company has been a member of EHEDG since 2010; divers process connections are certified as per EL - Class I. Precision turning and polishing assure a surface quality of the wetted parts with a medium surface roughness of Ra ≤ 0.8 μm. This surface roughness can be improved to values of Ra ≤ 0.4 μm on customer request.

According to the firm, in closed systems, the components can be cleaned by means of ‘Cip’ or ‘Sip’ procedures – perfect cleanability from the outside is attained with stainless steel housings with a degree of protection of up to IP 69. In addition to this very extensive product range, the firm also offers the appropriate supply and evaluation units for the instrumentation equipment.
