Rosemount issued safety patent for Raman Process Analyzer

Rosemount Analytical (Orrville, OH) has obtained a patent on a safety control feature for its Raman Process Analyzer and other optical analyzers.

The instrument uses the Rayleigh backscatter principle to provide reliable laser cessation for increased safety, which when the probe is removed from the process, the amount of Rayleigh backscatter decreases drastically causing the laser within the probe to immediately and automatically shut off for operator safety. If the process vessel is empty or if the fiber optic cables are damaged, the laser automatically shuts off, which reduces the potential for ignition. This design requires no hazardous wiring to be run from the analyzer to the probe.

The Raman Analyzer acts not only as an analyzer, but also as a server providing instant diagnostics, calibration capabilities, alarms, and process information anywhere the internet is accessible in an easy to manipulate web page format.
