2-2 Model 3321 Aerodynamic Particle Sizer
Spectrometer
Mount i n g the S ensor
The Model 3321 APS™ spectrometer requires no special mounting
requirements other than the ventilation requirements (see below). The
cabinet has four non-marking rubber feet that give the instrument a good
grip on clean, level surfaces. The rubber feet (Figure 2-1) are installed in
the cabinet using integrated 8-32 UNC threaded fasteners and can be
removed (by unscrewing) to allow other mounting fasteners to be used.
Note: If the cabinet is mounted to a plate, drill holes in the plate to match
the ventilation holes in the bottom of the cabinet or use standoffs to
raise the bottom of the cabinet at least ½ inch (1.2 cm) above the
mounting plate.
