Figure 2-1: Analyzer modular design
The analyzer’s modular design is suited for quick repair. All modules are easily replaced in the field in
minimal time. See section 10.4.3 for a recommended spare parts list.
2.2 Cast aluminum enclosure
The explosion-proof enclosure consists of a cylindrical shaped cast aluminum housing, powder coated,
with front and rear end caps for access to internal components. Figure 2-2 through Figure 2-5 show
the outline dimensions of the NGC8200 and PGC1000.
The end caps have precision-engineered threading. The enclosure and all fittings, including feed-
through, MMI connection, and breather, are tested to Nema/Type 4X. Unauthorized removal of the
end caps is protected with a 1/16” hex socket set screw on each end cap.
Entries in the explosion-proof enclosure constitute a flameproof joint. Flameproof joints, including
threaded entries in the explosion-proof enclosure, are not intended to be repaired.
This enclosure may be pipe-mounted on a meter run using a pipe saddle, stand-alone pipe-mounted,
shelf-mounted, or optionally mounted in an environmental enclosure. The device may be directionally
positioned using 1/8” hex socket set screws located in the neck of the enclosure.
