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
for a recommended spare parts list.

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.

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.
