Trace Oxygen Analyzer Installation 3

Installation

3.1 Location

With proper shielding of the leads, the analyzer and the readout device can be separated by as much as 1,000 feet. However, they should be placed as close together as possible. For the most convenient operation, the read- out recorder or meter should be within view of the controls, particularly when the unit is being calibrated. Figure 2-1 depicts a typical system layout. Other location considerations:

1)The analyzer should be sheltered from the elements.

2)Ambient temperature must be within 30 to 120 °F.

3)The unit should not be subject to excessive shock or vibration.

4)It should be as close as possible to the sample point.

5)There must be access to the back and side of the unit for connection or maintenance of sample lines and power.

NOTE: Since the level of the electrolyte in the measuring cell is critical and the water level control system for the humidifier is gravity sensitive,

THE ANALYZER MUST BE MOUNTED SO THAT THE BOTTOM OF THE CASE IS LEVEL.

3.2 Electrical Connections

A diagram of the necessary electrical connections is shown in Figure 2-2.

Note: See the Interconnection Diagram (drawing A-37526) included in the back of this manual, as well as any Addenda that may be included with this manual for information specific to your instrument.
