MSA Ultima X - Sample Line Placement; Caution

The in-line filter must be used before the aspirated pump to
prevent water entry from damaging unit.
• In-line filter (P/N 10051406) must be used somewhere along
the tubing length. Ensure that the arrow on the in line filter is
pointing towards the Aspirated Sampling Module.
• If installing additional Ultima X Gas Monitors, install tubing
between units as shown in FIGURE 2-1. Use tubing compatible
with the gas being sampled.
• MSA tubing is available (P/N 600771).
Sample Line Placement
The Aspirated Sampling Module draws a gas sample to the internally-
mounted Ultima X Gas Monitor sensor.
• The Aspirated Sampling Module can be mounted up to 100 feet
(30 meters) away from the monitored area.
• It uses 3/8-inch OD tubing to connect the Aspirated Sampling
Module sample inlet to the end of the sample line in the monitored
area. Tubing must be compatible with the sampled gas.
• It takes a maximum of 30 seconds for the sample gas to reach the
Aspirated Sampling Module when 50 feet (15.25 meters) of tubing
is used:
• To decrease this time, shorten the sample line length.
• It is generally good practice to make the sample line as short
as possible.
• Depending on the gas characteristics, the end of the sampling
tubing and the sample inlet should be mounted to best optimize
sampling of that particular gas. Consult your architect, facility
manager or safety engineer for guidance in proper placement of
the sampling tube inlet.
• Testing for ventilation patterns is useful in establishing sample inlet
location. Smoke tubes (P/N 458481) are useful in measuring the
direction and rate of air flow to determine which areas to monitor.
• The particulate filter provided should be used at the sample
end of the sample line to help prevent dirt and dust from clogging
the sample line. This filter must be compatible with the gas
being sampled.
