User-Supplied Items
Interconnect Wiring
The user must supply all wiring for serial communication, analog
output (max cable resistance <900 Ohms), and alarm relays. Recom-
mended wire is 22 gauge, twisted/shielded pair.
The terminal blocks in the customer connection box are sized for
02–4.0 mm
0.6 nm and 0.8 nm (85.1 to 113.5 in-oz).
External Sample Tubing
Standard recommended sample gas input tubing is 1/4" stainless steel
tubing (6mm for the OC6E metric connection fittings version), stain-
less steel. Sample input tubing length should be as short as possible.
Secondary Process Seals
Secondary process seals must be used on all conduit entry points at
the customer connection box to prevent gas/liquids from venting to
nonclassified locations.
Sample Pressure Requirements
AMETEK recommends pressure settings between -4.5 and 10 PSIG.
Minimum input pressure:
Maximum pressure:
A sample cell pressure sensor located in the electronics box is used to
monitor inlet pressure (shown below).
Consult plant safety personnel for appropriate exhaust venting
guidelines for specific sample gas type.
