Flame Photometric Detector (FPD) Module
|
 |
For Rosemount Analytical Model 500 and
700 Process Gas Chromatographs
The Flame Photometric Detector (FPD) Module enables the
measurement of trace sulfur compounds when integrated with
Rosemount Analytical Model 700 or Model 500 Process Gas
Chromatographs. The Flame Photometric Detector and associated
electronic boards are installed in temperature controlled flame-proof
enclosures and mounted on a stand complete with flame air and
hydrogen controls. This design eliminates the need for instrument air
and ambient temperature control - greatly reducing installation cost
of the process gas chromatograph. The FPD Module comes fully
integrated into a Rosemount Analytical Model 500 or Model 700 Process
Gas Chromatograph. The FPD Module is ATEX approved for Zone 1
& 2 locations and suitable for installation in Class I, Groups B, C & D,
Division 1 locations.
