| For the determination of the resonant frequency of materials.
Principle
The principle used in the E-Meter Mk II™ is based upon the
determination of the fundamental resonant frequency of vibration
of a specimen generated by an impact and sensed by an accelerometer.
The frequency spectrum is computed and displayed by the meter.
For the determination of the resonant frequency of
materials.
The E-Meter Mk II™ measures the resonant frequencies of the
three different modes of vibration – Longitudinal, transverse
(Flexural) and torsional.
From these the following material characteristics
can be calculated –
Young’s Modulus of Elasticity,
Modulus of Rigidity and
Poisson’s Ratio.
