3.4 Diffusion Probe
The sample gas flow is diffused through the sample filter element into the sensor
area. The gas, which passes the probe, must represent the gas to be tested and
extracted from a location with laminar flow. Holes and leaks in the gas ducting
system before and after the probe may influence the accuracy of the measurement.
The probe shall be placed so that it is protected against mechanical damage. The
flue gas temperature cannot exceed the given temperature limit of the diffusion
probe.
For mounting of the diffusion probe, there are two mounting types:
Probe with welding socket (see Figure 3-3 and Figure 3-4)
Probe with thread (see Figure 3-5 and Figure 3-6)
When mounting the probe on the stack, make sure that the back plate of the probe
is mounted with the sampling hose connection facing down and the probe protec-
tion house mounted in a vertical position of the stack. Please see Figure 3-1 and
Figure 3-2 for the installation of the probes.
