Ametek 3050-DO

PN 305725901, Rev YF
• System Tubing
Recommended system tubing is 1/8 inch OD, 316 stainless steel meeting
ASTM #632 specications (AMETEK PN 257707000 or equivalent).
• Dry Reference Gas
A dryer (AMETEK Dryer PN 305400901S or equivalent) is required to dry
Reference gas to less than 0.025 PPMV.
A dryer (AMETEK Dryer PN 305580901S or equivalent) is required to dry the
gas to less than 0.01 PPMV to Zero calibrate the 3050-DO Analyzer.
Dryers must be periodically replaced. In normal use, the dryer (PN
305400901S) should dry a 50 PPM Reference gas to specication for one (1)
year.
Sample Gases
The 3050-DO Analyzer is designed to operate on a clean gas stream;
specically, the Sample gas stream must be free of particulates and aero-
sols. If the 3050-DO Analyzer is being used on a clean gas stream (i.e.,
free from particulates and aerosols), AMETEK Process Instruments recom-
mends that the analyzer be installed in accordance with the information
provided in the following sections of this manual. However, if the process
gas stream contains, or has the possibility of containing particulate mate-
rials, AMETEK Process Instruments recommends that a inline, 1/8" tube 7
UM lter (supplied) be installed an the inlet of the analyzer. AMETEK lter
(PN271639001) is ideally suited for this purpose, and will mount directly
on the inlet tting of the analyzer. While installing this lter at the inlet
of the analyzer will protect the analyzer from any particulates present in
the Sample gas, it will also increase the response time of the system. This
increase in response time is caused by the large surface area of the lter
element.
AMETEK Process Instruments manufactures sample systems for the
3050-DO Analyzer that are designed to remove particulates and aerosols
from a gas stream, protecting the analyzer from damage, while maintain-
ing fast sample system response. If you have questions concerning the
sampling requirements of your process gas, please contact us at any of the
addresses located in the front of this manual.
Sample Pressure and Temperature Requirements
Pressure reduction is user supplied to ensure sample pressure to the
analyzer remains within the range of 20–50 PSIG. The pressure reducer/
regulator with gauge should be installed near the Sample tap between the
tap and analyzer (see Figure 2-3). For optimum performance, sample line
should be heat traced to maintain a constant sample temperature. Opti-
mum Sample gas input is 60 °C.
