Snubber Diffusion Assembly
The standard snubber diffusion assembly (Figure 1-7) is satisfactory for most
applications, however the snubber diffuser should not be used in flue gas
temperatures above 500
°
C (932
°
F).

Assembly
Ceramic Diffusion Assembly
The ceramic diffusion assembly (Figure 1-8) is the traditional design for the
probe. Used for over 25 years, the ceramic diffusion assembly provides a
greater filter surface area.

Assembly
Cup-Type Diffusion Assembly
The cup-type diffusion assembly (Figure 1-9) is typically used in high
temperature applications where frequent diffusion element plugging is a
problem. The cup-type diffusion assembly is available with a 40 micron,
sintered, Hastelloy element.
