Instrument Gas Connections (Figures 3.2 and 3.4)
POSSIBLE INJURY! The tubing, valves and other apparatus
!
physical injury to the operator or bystander is possible.
Sample gas connections are made via the Gas In (2) and Gas Out (1) ports located on
the rear of the instrument as shown in
The HygroPort I.S. is supplied with a sintered disc filter installed in the Gas In port,
and with a large bore orifice fitting installed in each of the gas ports. These fittings
have an 1/8" NPT female thread to allow the user to connect other components of
their choice. A range of available fittings and sample flow accessories are shown in
.
Figure 3.4
Atmospheric pressure or system pressure dewpoint can be measured depending on the
configuration of the orifice fittings shown in Table 3.1.
For gas pressures outside the range 15-150 psig (1 to 10 bar), the instrument
requires external flow control components, as shown in Figure 3.4
