The user must supply all wiring for serial communication, analog
output, and alarm relays. Recommended wire is 22 gauge, twisted/
shielded pair.
External Sample Tubing
Sample input tubing length should be as short as possible.

Exhaust pressure must be 0 – 15 PSIG.
Input and exhaust tubing must be fitted with female 1/4" VCR con-
nectors.
5-20 PSIG (34.5-138 kPa)
5-20 PSIG (34.5-138 kPa)
7-20 PSIG (48.3-138 kPa)
Consult plant safety personnel for appropriate exhaust venting guide-
lines for specific sample gas type.
For optimum performance, sample tubing should be thermally con-
trolled to maintain a constant sample input temperature. Optimal
results are obtained with the sample line maintained at 60 °C.
Recommended sample gas input tubing is 1/4 inch OD, electro
polished 316L VAR stainless steel (AMETEK #257707002 or equiva-
lent).
