3.2.2 High Temperature Rosemount SAM42 Acoustic Particle
Monitor Location
The same installation methods can be used as described in Standard
temperature Rosemount SAM42 Acoustic Particle Monitor location
when installing SAM42 HT version. However, additional consideration
is needed when choosing the mounting orientation due to the
higher process temperatures. It is suggested the device be mounted
horizontally (3 o’clock or 9 o’clock) or in some cases at the base (6
o’clock) to minimize convective heat transfer from the pipe to the
sensor. See Figure 3-4.

Surface preparation
Before mounting the Rosemount SAM42 Acoustic Particle Monitor,
ensure the surface of the pipe has been prepared so that the device
has optimal contact with the pipe surface. Using a flat file, wire brush
or sandpaper, ensure that a 25 mm x 25 mm square section of the
surface of the pipe is:
• Bare metal (no coatings etc.)
• Free of debris
