Trace Oxygen Analyzer

Installation

 

 

 

A flowmeter and flow restrictor are parts of the sample system and assist in setting the flow of the gas. The restrictor is installed upstream of the analyzer while the flowmeter is installed on the vent side.

Adjust the sample pressure at the regulator to provide a flow rate of 0.4-0.5 SCFH. It is important that the sample vent connection does not restrict the sample flow. The sensor is designed to operate at atmospheric pressure. Restricting the sample vent line will pressurize the sensor, alter the O2 reading, and reduce the sample flow.

Sample and Span pressure should not exceed 2000 psig (13.8 Mpa)

3.6Installation Checklist

Before connecting the instrument to the power source and turning it on, make sure you have:

Correctly installed the Sample and Exhaust gas lines

Checked for leaks

Set the flow

Once the above checks have been made, you can connect to the power source. The instrument is now ready for operation.
