SKF Microlog Analyzer CMXA 51-MSHA

The only MSHA-approved vibration data collector available for hazardous ‘gassy’ areas of U.S. mines

The SKF Microlog Analyzer CMXA 51 has been certified and approved by the U.S. Department of Labor’s Mine Safety and Health Administration (MSHA) for use in hazardous “gassy” areas of all mine operations in the United States. The certification stipulates that the SKF Microlog Analyzer meets MSHA standards as a “permissible” and “intrinsically safe” device for areas where potentially explosive firedamp (a flammable gas, usually methane) is commonly found.

Prevent ignition of gas and dust fuels

The newly designated SKF Microlog Analyzer CMXA 51-MSHA has been designed and manufactured to achieve MSHA “system approval” certification using methods applicable to intrinsic safety. The design reduces the amount of generated energy (heat) and effectively eliminates the risk of the device igniting a flammable mixture.

  • Tested for use in methane-air mixtures
  • MSHA approval no.18-A170001- 0
