Hazardous Area Oxymitter DR

SECTION 2

INSTALLATION

The Hazardous Area Oxymitter DR and probe abrasive shield are heavy. Use proper lifting and carrying procedures to avoid personal injury.

Before installing this equipment, read the “Safety instructions for the wiring and installation of this apparatus” at the front of this Instruction Bulletin. Failure to follow safety instructions could result in serious injury or death.

2-1 MECHANICAL INSTALLATION

If the probe will be installed into an existing lo- cation, proceed to paragraph 2-1b.

a.Selecting Location

1.The location of the Hazardous Area Oxymitter DR in the stack or flue is most important for maximum accuracy in the oxygen analyzing process. The Hazardous Area Oxymitter DR must be positioned so the gas it measures is representative of the process. Best re- sults are normally obtained if the Haz- ardous Area Oxymitter DR is positioned near the center of the duct (40-60% insertion).

2.Longer ducts may require several Haz- ardous Area Oxymitter DR units since the O2 can vary due to stratification.

3.A point too near the wall of the duct, or the inside radius of a bend, may not provide a representative sample be- cause of the very low flow conditions.

4.The sensing point should be selected so the process gas temperature falls within a range of 0° to 704°C (32° to 1300°F). Figure 2-1through Figure 2-4provide mechanical installation refer- ences. The ambient temperature of the termination housing must not exceed 65°C (149°F).

5.Ducts and stacks that operate under negative pressure will draw air in through any holes or torn seals, sub- stantially affecting the oxygen reading. Therefore, either make the necessary repairs or install the Hazardous Area Oxymitter DR upstream of any leak- age.

6.Ensure the area is clear of internal and external obstructions that will interfere with installation and maintenance. Al- low adequate clearance for removal of the Hazardous Area Oxymitter DR (Figure 2-1).

b.Installation

1.Ensure all components are available to install the Hazardous Area Oxymitter DR. If equipped with the optional ce- ramic diffusion element, ensure it is not damaged.

2.The Hazardous Area Oxymitter DR may be installed intact as it is received.

NOTE

An abrasive shield is recommended for high velocity particulate in the flue stream (such as those in coal-fired boilers, kilns, and recovery boilers).

3.Weld or bolt adapter plate (Figure 2-4)onto the duct.
