Hazardous Area Approved Accelerometers
Accelerometers approved for use in hazardous areas are certified by several different international programs (ATEX, CSA/ETL and IECEx) as well as several country-specific certifications. These certifications are commonly required when installing sensors in a potentially explosive area. Some installations may require an additional energy-limiting barrier, depending upon the classification of the hazardous area.
Ensure proper selection of sensors for potentially explosive areas
Many industrial environments contain potentially explosive materials, including manufacturing facilities, power generation plants, and oil & gas processing facilities. Ignition of these potentially explosive materials could cause catastrophic damages, worker injury, or even death. To prevent such disasters, many IMI products are tested to international standards to ensure that they could prevent or contain an explosion.
Certified standards for safety compliance
Sensors approved for use in explosive environments are certified according to the following standards, signifying compliance with stringent safety, health and quality requirements:
- European Union Directive 2014/34/EU Equipment for Potentially Explosive Atmospheres (ATEX)
- International Electrotechnical Commission's IEC Ex Rules 01-05 (IECEx)
- US National Fire Protection Association NFPA 70: National Electric Code® (CSA or ETL)
- Canadian Standards Association CSA C22.1: Canadian Electrical Code (CSA or ETL)
