Figure 3-7: Pneumatic Connections–Basic Configuration–Using Gas Dilution Calibrator
1. Attach a sample inlet line to the sample inlet port. The SAMPLE input line should not be more than 2
meters long.
NOTE
Ideally, the pressure of the sample gas should be at ambient pressure (0 psig).
Maximum pressure of sample gas should not exceed 1.5 in-Hg over ambient.
In applications where the sample gas is received from a pressurized manifold, a vent
must be placed as shown to equalize the sample gas with ambient atmospheric
pressure before it enters the analyzer.
This vent line must be:
At least 0.2m long
No more than 2m long and vented outside the shelter or immediate area
surrounding the instrument.
2. Attach sources of zero air and span gas (see Figures 3-3 through 3-8 inclusive).
Span Gas is a gas specifically mixed to match the chemical composition of the type of gas being
measured at near full scale of the desired measurement range.
In the case of CO
2
measurements made with the Teledyne Instruments Model 360E Analyzer it is
recommended that you use a gas calibrated to have a CO
2
content equaling 80% of the range of
compositions being measured.
