Ametek 5100 HD - Gas Connections

3-8 | Model 5100 HD Analyzer
Inlet pressure must be kept at less than 69 kPa (10 PSIG). If a
regulator is necessary on the sample line to maintain required
sample inlet pressure, it should be of a type suitable for use with the
sample gas, and for the area classication. Heated regulators are
recommended for large pressure drops with certain gasses.
Check inlet pressure and ow rate on a weekly basis to ensure
correct pressure.
Gas Connections
Locate the analyzer as close as possible to the sample source and install a main
process shut-o valve at the sample tap. All connections to the 5100 HD are
made using 1/4”tubing (6mm for metric option) compression ttings. These
ttings are located on the right side of the system enclosure. They include:
sample inlet, liquid separator drain, and sample exhaust.
When connecting the sample line, minimize the amount of time that
the analyzer gas ttings are left open. Otherwise signicant amounts
of moisture may be introduced into the sample cell from the ambient
air.
1. Remove the tting caps from the sample inlet tting and exhaust tting.
Keep the tting caps in case you have to ship the analyzer or if it has to be
disconnected for an extended period of time.
2. Connect the sample input tube to the analyzer sample inlet valve.
3. Connect the exhaust tube to the analyzer exhaust. The exhaust must be vented to an
appropriate vent system.
All sample outlets should exhaust to atmospheric pressure, either
outside or into a vent, not into the workplace. It is the customer’s
responsibility to ensure potentially hazardous samples are removed
safely and to supply all necessary tubing to connect the exhaust to
a suitable location. To prevent condensation in the exhaust draining
back to the analyzer ensure a continuous downward gradient on the
line, or t a suitable trap to the line.
4. The separator inside the sample section removes entrained liquids and
particulates from the gas before it passes through the sample cell. For this
reason, the bypass or drain valve is left OPEN to allow the residue to exit the
analyzer. Ensure that the valve is turned slightly to the OPEN position.
