Informatie

* Force rating 10 Newton (2,25 ibf) Sine Peak * Frequency range DC to 1 8 kHz ■ First axial resonance above 18 kHz * Max. bare table acceleration 550 ms-2 (56 g) ■ Rugged construction USES: ■ Calibration of accelerometers * Vibration testing of small objects ■ Educational demonstrations ■ Mechanical impedance measurements 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.
