PGC Certification
This simple pressurization technique for the
PGC5000 is considered an improvement to the
process gas chromatograph analyzer by allowing for
a continual operation without possible disruption
caused by interlocking the electrical power to the
pressurization system. When operated in a zone 1
area, the user of the PGC5000 analyzer is simply
responsible for:
• Operating the analyzer within the manufacturer’s
established parameters, as described in the
product manuals and the CE conformity
declaration’s special conditions for safe use
• Providing a reliable supply of protected air for the
enclosure purge and pressurization system
• Monitoring the alarm state of the pressurization
system in normal operation
• Responding to the alarm condition of the
pressurization system, which may require
restoring the supply of protected air or the
removal of electrical power and proper isolation
of remaining hazardous live circuits if the area is
potentially hazardous
