Noise resistant 3D monolithic piezoelectric transducer

The article describes the operation principles of simple noise resistant 3D piezoelectric transducer based on monolithic piezoelectric cell with differential outputs, measuring vibration vector at one point of interest.
It is shown that the proposed transducer has much more simple construction than the conventional 3D piezoelectric transducers. Coupled to a standard 3-channel preamplifier, it is quite sufficient for 3D vibration measurements with an accuracy depending mainly on transversal sensitivities. Working together with a special «orthogonizing» unit it can be used for precise noise resistant 3D vibration measurements without error due to the transversal sensitivities.

Keywords: piezoelectric transducer, 3D, sensitivity, vector, monolithic, piezoelectric, cell, vibration, orthogonizer, accuracy.
