7.0.3 Sampling Gas from a Pressurized Source
When the gas is to be sampled from a pressurized source, such as a pressurized line, a pressure
relief mechanism should be employed so as not to force or restrict the flow of gas into the unit.
Refer to the Applications Manual for sample pressure recommendations. See Table 11 - Sampling
System Specifications on page 71 for allowable pressure, temperature and flow rate.
WARNING
Personal Injury and Equipment Damage: Sample allowable pressure must
not be exceeded, or may cause the gas cell to over pressurize. Care should
be taken to review Table 11 - Sampling System Specifications on page 71.
CAUTION
Equipment Damage: Restricting the gas flow on either the intake or the exhaust side may cause
the gas cell to over pressurize. Care should be taken to remove any port caps or other flow
barrier before switching on the analyzer. Also make sure the exhaust routing is appropriate for
your specific application.
CAUTION
Equipment Damage: Pressure relief mechanism should be employed when sampling gas from
a source other than the ambient in order to avoid damage to the analyzer.
7.0.4 Cleanliness of Sample Stream
CAUTION
Equipment Damage: The sample stream must be clean of particles that could block the light
path and potentially accumulate on the windows, and potentially damage the unit. It is ultimately
the user’s responsibility to ensure a clean sample stream. We recommend an inline 10 micron
particulate filter for most applications. Contact Servomex for more information.
