Figure 2-2: Recommended External Sample System
The sample path within the transmitter is a straight-through path.
Gas encounters no dead space. This minimizes residual gas pockets that
can interfere with accurate analysis.
Stainless steel 1/4” tube fittings are installed (6mm are available)
for connecting the external sample system to the transmitter. For metric
system installations, 6 mm adapters can be supplied if needed. The
sample gas path through the transmitter is shown in Figure 2-3.
