TDLS8200: Maintenance-free, SIL2 certified and explosion-proof

In almost every chemical production plant, it is always necessary to store various substances in containers or tank farms. Depending on the chemical substance, this can from time to time result in an explosion hazard. For this reason, elementary protection against a possible explosion must be provided. In the best case scenario, this should be done in such a way that no explosive gas mixture can form in the gas phase of the container. In the age of ever-increasing safety requirements, a current safety assessment may make it necessary to actually record the oxygen content – especially if the device in question has been classified as a SIL (safety integrity level) application.  This is exactly where Yokogawa’s TDLS8000 laser comes into play.

EuroPACT in Copenhagen: EU-wide PAT Trialogue

For several years Werner Worringen has been working as Industry Marketing Manager Analytical Solutions at Yokogawa Germany. Since then he has also been involved in numerous committees relating to process analytics. As a member of the extended executive board, he is also a member of the Process Analytics Working Group (AK PAT), which was established in 2005 and now has 365 members. Working group of the Division of Analytical Chemistry within the German Chemical Society (GDCh), which works closely with DECHEMA (Society for Chemical Engineering and Biotechnology). This is also the case with regard to EuroPACT, which will be held in Copenhagen in May.

PAT-Demonstrator – NOA is the ideal partner

Where NOA comes into play: If process analysis technology delivers more and more complex data and experience sometimes requires changes, then we need an additional piece of intelligence. This is not properly stored in the analyzer. Because the type of intelligence is also determined by the process. In the control system, the additional data becomes tight; changes are possible there, but not necessarily popular. A separate software, for example in the form of an app, frees us from these restrictions and gives us the necessary flexibility for specific adaptations.
