SKF CMXA 51-MSHA Manual

SKF Microlog Analyzer
CMXA 51-MSHA
U.S. Mine Safety & Health Administration (MSHA)
Permissable hand-held portable data collection system
The SKF Microlog Analyzer
CMXA 51-MSHA for vibration
data collection in gassy mines
in the United States
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.
All coal mines in the U.S. are considered
"gassy" and only MSHA certified instruments
are allowed to be used in gassy "permissible"
areas. Certification to the MSHA standard
affirms that the SKF analyzer is properly
designed to perform safely in such
hazardous mine environments by
preventing any possible ignition of gas
and dust fuels.
The SKF Microlog Analyzer CMXA
51-MSHA is a rugged, portable, handheld
condition-monitoring instrument for
collecting vibration, process, and dynamic
data from machinery.
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.
