Functional safety in the process industry is a topic that has very much moved centre stage since IEC 61508 came into force. It is frequently only indicated by the abbreviation SIL. But what exactly is SIL and how can it be used to control process valves?

In biotechnology, the content and growth of biomass is an important process variable. There are different ways of quantifying this directly in the reactor. The methods currently used have advantages and disadvantages with regard to optimal process control and costs. This white paper demonstrates how biomass concentration and growth in biotech processes can be calculated using soft sensors and existing measurement signals.

This white paper has the following aims:

• What is SIL, why is the topic relevant for plant operators, and what are the common misunderstandings?
• What do certificates mean and how do you read them correctly?
• To what extent do durable components offer a helpful advantage?

In many process automation applications, the pressure and flow of gases are controlled. Explosion protection requirements mean that an inert atmosphere is often created and maintained in reactors and process tanks in a plant. Learn more about the advantages of the proportional valve technology.

The VTOP is ideal for control applications with positioner and additional instrumentation. The pneumatic extension modules facilitate a complete setup, without tedious searches for components and time consuming installation, and thus greatly simplify maintenance. The new installation concept VTOP with patented, integrated air routing allows you to combine the individual modules you need, and easily retrofit other modules at any time.

Pablo Ruiz, Product Manager for Process Automation at Festo, presents the quarter turn actuator DFPD: an extremely modular and productive all-rounder!

The CMSH provides you with all the benefits of a highly dynamic, low-wear positioning system with high air output and a long service life. You now only need one device for the fast and precise control of actuators, whether large or small, linear or rotary, single- acting or double-acting. Together with the low internal air consumption, this reduces costs. Featuring 2-wire technology, HART communication, condition monitoring functions and a modular system with many variants, the CMSH offers excellent flexibility for a great number of applications.
