The Mini-Shaker Type 4810 is a small machine for the dynamic
excitation of lighter objects, it is manufactured from
quality materials to a high degree of precision and has
proved to be a reliable and versatile tool in dynamic testing.
Type 4810 is well suited as the motive force Generator in
mechanical impedance measurements where only smaller forces
are required.
It can also be used in the calibration of vibration
transducers, both to determine their sensitivity by
comparison with a standard accelerometer, and to determine
their frequency response up to 18 kHz.
The Mini-Shaker is of the electro-dynamic type with a
permanent field magnet. A coil, which is an integral part of
the table structure, is flexibly suspended in one plane in the
field of the permanent magnet. An alternating current
signal, provided by an external Oscillator is passed through
the coil to produce a vibratory motion at the table.
