SM5000 Sampling Module - DC Pump Model
2.4 Sample Line Placement
The Pump Sampling Module draws a gas sample to the internally mounted Ultima X, Ultima X5000, or
S5000 Gas Monitor sensor.
• The Pump Sampling Module can be mounted up to 100 feet (30 meters) away from the monitored area.
• It uses 1/4-inch (6.35 mm) OD tubing to connect the Pump 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 Pump 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.
• Alternative end of line filters are available if sampling from wet areas. If sampling from a hot and moist
area, use in line filter PN 637921. If sampling from an outdoor area where the sample line end is at risk
for submerging under water, use in line filter PN 10015787. Both filters are purchased separately.
• If installing in an area that is hosed-down or sanitized, use the water deflector accessory PN 10087383
for end of line sample, available for purchase separately.
• It is recommended that a stainless steel of Teflon (Trademark of the DuPont Company) sample line be
used for monitoring gases that are highly reactive such as:
• Nitrogen dioxide
• Sulfur dioxide
•Chlorine
• Chlorine dioxide
• Hydrogen chloride
•Ammonia
• Fluorine
•Bromine.
• With the above gases, use filter (P/N 637921). The filter and sample line should be inspected periodically
and replaced if dirty.
CAUTION!
Do not attempt to clean the sample line by applying compressed air.
All gas monitors must be mounted in ambient, interference-free air; otherwise, erroneous readings may
result.
