Magnetic Mount Procedure
Magnetic mounting provides a convenient means for making portable measurements and is commonly used for machinery
monitoring and other portable or trending applications.
Note: The correct magnet choice and an adequately prepared mounting surface are critical for obtaining reliable
measurements, especially at high frequencies. Poor installations can cause as much as a 50% drop in the sensor frequency
range.
Not every magnet is suitable for all applications. For example, rare earth magnets are commonly used because of
their high strength. Flat magnets work well on smooth, flat surfaces, while dual-rail magnets are required for curved
surfaces. In the case of non-magnetic or rough surfaces, it is recommended that the user first weld, epoxy or
otherwise adhere a steel mounting pad to the test surface. This provides a smooth and repeatable location for
mounting.
ALL SURFA CES SHOUL D BE FLAT AND SMOOTH
STEP 1 After choosing the correct magnet type, inspect the unit, verifying that the mounting surfaces are flat and
smooth.
STEP 2 Stud-mount the accelerometer to the appropriate magnet according to the guidelines set forth in Steps 2
and 3 of the Standard Stud Mount Procedure.
STEP 3 Prepare a smooth, flat mounting surface. After cleaning the surface and checking for burrs, wipe on a
light film of silicone grease, machine oil or similar-type coupling fluid.
STEP 4 Mount the magnet/sensor assembly to the prepared test surface by gently "rocking" or "sliding" it into
place.
Note: Magnetically mounting accelerometers carelessly has the potential to generate very high (and very
damaging) g levels. To prevent damage, install the assembly gently. If unsure, please contact the factory
