Hazardous Locations
SCOUT and vbSeries instruments are rated differently for hazardous
environments — SCOUT instruments hold an IECEx/ATEX rating, while
vbSeries instruments are CSA-certified.
CSA Certification — vbSeries Instruments
Your Portable Vibration Analyzer has been approved by the Canadian
Standards Association (CSA) for use in hazardous locations that meet the
following classifications — Class I; Division 2; Groups A, B, C, and D.
These instruments are clearly identified with the CSA logo and a
Hazardous Locations information panel. The Class I Division 2
classification is officially defined in the Canadian Electrical Code, part 1.
In summary, it is a location in which volatile flammable gases or vapors
are present but confined within closed systems from which they can
escape only in case of accidental rupture or abnormal operation; or in
which ignitable concentrations of gases are normally prevented by
positive pressure or mechanical ventilation, and which might become
hazardous through abnormal operation of the ventilation equipment.
The approval specifically covers use in the United States of America and
any other countries which recognize the CSA certification.
When using a certified instrument in a hazardous location, the
installation must comply with the Installation Control Drawing for
Hazardous Locations, including all its footnotes and warnings.
Your instrument will be supplied, complete with appropriate sensors for
use in Class I Division 2 environments. As indicated in the diagram, you
can use alternative sensors, provided these are certified for use in these
locations, and provided their entity parameters meet the limits shown in
the drawing.
