  October 15, 2019


Sellersville, PA: Control Instruments Corporation, the experts in gas detection and solvent vapor monitoring have just received their SIL 3 certification for the PrevEx Series 670 Flammability Analyzer through exida. 

Designed to monitor lower flammability limits, the PrevEx flammability analyzer is equipped to be fast with a less than one-second response time. Providing both universally consistent and reliable readings, this analyzer is designed to ensure safety. With the ability to perform under the demands of the industrial environment, the PrevEx resists contamination with a corrosion resistant heated sample train through which the sample is delivered.  

To ensure its reliability, Control Instrument’s chose exida, the global leader in functional safety, cybersecurity, and alarm management for the process industries for their SIL certification. exida worked alongside of the team at Control Instruments not only in the certification of their product, but also providing expert explanations of the IEC 61508 standard and realistic failure analysis predictions needed for their customers SIL 3 compliance. 

“The value exida provided us has been exceptional. Their technical expertise, combined with a dedication to timeliness and a high level of efficiency, has made our project a success. The assessor's ability to communicate clearly and completely at all stages helped tremendously.” Comments Chris Schaeffer, Project Manager for Control Instruments. “We have a global market  and needed a Certification Body with global recognition. exidais recognized as such by our worldwide customers.” 

Dave Butler, Evaluating Assessor for this project adds, “Working with Control Instruments was a pleasure, despite an aggressive assessment schedule.  Their knowledge of their product’s functions, design and documentation enabled us to complete this project in short order.  We look forward to working with Control Instruments again in the near future.”
