Developing a hazardous area solution for particle measurement systems
Working with one of the leading global manufacturers of precision instruments for use in laboratories and manufacturing applications.
Overview
The client had developed a new instrument for real-time analysis of particles in pharma & biotech based manufacturing processes, and came to Expo to develop a version that could be deployed in hazardous areas.
Project Brief
Re-package the existing safe area particle measuring system suitable for use in Class I, Division 1 & Zone 1 hazardous areas, while staying close to the original footprint.
Challenges
- The resulting enclosure, suitable for use with a purge and pressurization, needed to maintain the original footprint and form factor as much as possible
- The system would need to include the means to isolate and control power to the device in order to comply with the various codes & standards.
- The enclosure internals would need to be easily accessed for adjustments and maintenance.
- The solution required apparatus certification for use in various markets around the world.
Solution
- Working with the client's engineers, Expo designed a new instrument enclosure that was suitable for pressurisation, while allowing access to the internal components.
- A custom X purge system and relief valve were integrated into the enclosure alongside the existing instrument components, giving a sleek single-box solution.
- The completed system was successfully certified for Class I, Division 1 and ATEX & IECEx Zone 1 areas, permitting the client to access multiple markets worldwide.
