NDIR Gas Analyzer Instalation
Teledyne Analytical Instruments 9
• The analyzer weight must be supported at the bottom of the
casing.
• The analyzer should be installed in a place where ambient
temperature is within -5 to 45°C (max. 40°C when two optical
units are used, and the power supply is more than 200V AC), and
temperature fluctuation during operation is minimum.
• Where vibration is unavoidable, protect the analyzer from
vibrating. If necessary, install rubber or other vibration absorbing
material around the case to isolate any vibration from the support
structure.
3.3 Piping
Observe the following items when making gas connections to the
rear panel:
• Piping should be connected to the gas inlets and outlets at the
rear panel of the analyzer.
• Use a corrosion resistant tubing comprised of Teflon, stainless
steel or polyethylene to connect the instrument to a sampling
system. Even if there is a danger of corrosion, refrain from using
rubber or soft vinyl tubing. These materials will cause inaccurate
indication due to gas absorption from the tubing.
• Pipe connection port fittings are NPT 1/4” female thread (or 1/4”
RC). Piping should be cut as short as possible for optimum
response. About 4 mm inner diameter is recommended.
