Hazardous Area Oxymitter 5000
Ceramic Diffusion
Element Replacement
NOTE
This procedure applies to the ceramic diffuser element only.
General
The diffusion element protects the O
2
cell from particles in process gases.
The element does not normally need to be replaced, because the vee
deflector protects it from particulate erosion. In severe environments, the filter
may be broken or subject to excessive erosion. Examine the ceramic diffusion
element whenever removing the probe for any purpose. Replace if damaged.
Damage to the diffusion element may become apparent during calibration.
Compare probe response with previous response. A broken diffusion element
will cause a slower response to calibration gas.
Hex wrenches needed to remove set-screws and socket head screws in the
following procedure are available as part of a Probe Disassembly Kit,
Table 10-1.
Replacement Procedure
1. Follow the instructions given in "Removal and Replacement of Probe" to
remove the Hazardous Area Oxymitter 5000 from the stack or duct.
2. Loosen setscrews, Figure 9-10, using hex wrench from Probe
Disassembly Kit, Table 10-1 and remove vee deflector. Inspect
setscrews. If damaged, replace with stainless setscrews coated with
anti-seize compound.
3. On systems equipped with abrasive shield, remove dual dust seal
gaskets.
4. Use spanner wrenches from the Probe Disassembly Kit, Table 10-1, to
turn hub free from retainer.
5. Put the hub in vise. Break out old ceramic diffusion element with chisel
along cement line and 9.5 mm (3/8 in.) pin punch through cement port.
6. Break out remaining ceramic diffusion element by tapping lightly around
hub with hammer. Clean grooves with pointed tool if necessary.
7. Replace ceramic diffusion element using the ceramic diffusion element
replacement kit in Table 10-1. This consists of a diffusion element,
cement, setscrews, anti-seize compound and instructions.
8. Test fit replacement ceramic diffusion element to be sure seat is clean.
