Teledyne 7500ZA operating instructions Piping

NDIR Gas Analyzer Instalation

•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.

3.3Piping

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.
