5.9 Installation of accelerometer
If you need to set up a permanent measurement
point on a machine, but you expect not to drill any
hole on the machine, you may use the stud of
bonding type which can be fixed with a rigid
adhesive on the measurement point. We
recommend using the epoxy resin type or the
cyanoacrylate adhesive type, because the soft
adhesive type will significantly reduce the valid
frequency range of the accelerometer.
If the measuring point is a plane, you may use the
permanent magnet base to achieve a simple
installation. However, this method will make the
resonant frequency of the test accelerometer
reduced to 7kHz; therefore, it cannot be applied on
the measurement of more than 2kHz. The suction
force of the magnet can withstand vibration force up
to 1000 - 2000m/s², which is dependent on the size
of the accelerometer.
If the accelerometer is mounted on the top of a
handheld probe, it can help the rapid measuring
work. Because the overall stiffness reduces, the
