The product is multiple shear plate vibration transducer, which has very high sensitivity. It is intended for measurement up to micro g level. It has virtula immunity to strain and offers guarantee of low frequency integrity measurement. The noise level of the system is of 10-2pC. The bandwidth is restricted to 2 KHz and noise flow is significantly below 1 octave.
The noise of the amplifier increases because of the function of input capacitance. The transducer adds some mass at its attachment to a structure which imposes transparency constraint above which data corruption becomes excessive.
