Seals that monitor themselves

Seals that monitor themselves

Seals are increasingly being asked to do more than just seal. In the future, they should be able to forecast when they will break down and perform condition monitoring in real time – all on their own. As a technology specialist, Freudenberg Sealing Technologies is not just anticipating the steadily rising demands on seals but on future sealing materials as well. Now the company is presenting a new generation of smart seals that is becoming possible for the food and process industries, thanks to a combination of various material characteristics.

Smart Position Indicator keeps plant control systems reliably informed of manual valve positions

Smart Position Indicator keeps plant control systems reliably informed of manual valve positions

Refinery operators have a pressing requirement to improve the efficiency of flow control in their plants and they want to know from the Distributed Control System (DCS) if valves are open or closed. In a typical refinery, 10% of valves are actuated and 90% are manually operated. This poses a serious problem for end-users if the DCS does not accurately know how many manual valves are opened or closed, which limits the efficiency of their business operations.
To meet this challenge, Rotork Gears has introduced the SPI Smart Position Indicator.

Process observation using sight glass devices

Sight glass devices allow detailed observation of processes without requiring complex and often expensive sensor systems. In this article, we explain some common types of sight glasses, their advantages and disadvantages, as well as some important criteria for design and selection.
