Applications: pulverized coal, recovery boilers, lime kiln. Regardless or application, Emerson recommends abrasive shields with support brackets for 9 ft. (2,74 m), 12 ft. (3,66 m), 15 ft. (4,57 m), and 18 ft. (5,49 m) probe installations, particularly horizontal installations.
Manual applicable to your electronics. 1.2.2 Description Emerson designed the Oxymitter DR to measure the net concentration of oxygen in an industrial combustion process (i.e., the oxygen remaining after all fuels have been oxidized). The probe is permanently positioned within an exhaust duct or stack and performs its task without a sampling system.
Page 11
15 ft. (4,57 m) • 18 ft. (5,49 m) Emerson offers abrasive shields for applications where abrasive particulates are present. Acid-resistant cells are available for SO and HCl environments. Bypass and probe mounting jacket options are available for process temperatures above 1300 °F (705 °C).

Upgrading the Rosemount Oxymitter DR You can easily upgrade the Rosemount Oxymitter DR to a full Oxymitter 4000 or 5000. This provides an economical upgrade path for customers looking to preserve their probe investment upon the eventual failure of the signal conditioning electronics. To upgrade, add a small electronics package to the existing termination housing of the probe.
Figure 1-2: Ceramic Diffusion Assembly Snubber diffusion assembly The snubber diffusion assembly is satisfactory for most applications. This element is also available with a dust seal for use with an abrasive shield. Figure 1-3: Snubber Diffusion Assembly Rosemount Oxymitter DR...
Page 14
The shield protects against particle abrasion and condensations, provides a guide for ease of insertion, and acts as a positive support, especially for longer probes. The abrasive shield assembly uses a modified diffusor and vee deflector assembly, fitted with dual dust seal packing. Emerson.com/Rosemount...
