FIELD: measuring technology.
SUBSTANCE: invention relates to the field of measuring technology. The substance of the invention lies in the fact that the vibration sensor contains a housing, as well as a stand rigidly fixed in the housing, in the compartment of which there is a battery attached to the stand, the battery charging means is made in the form of a wired connection between an external power supply unit, a battery and a communication processor board through a complex electrical connector on the surface of the housing, while the piezoelectric ceramic sensitive element is made in the form of a cube of unidirectionally polarized and orthogonally oriented three pairs of piezoelectric segments combined into a single whole.
EFFECT: improving the performance of the wireless vibration sensor and simplifying the design of its sensing element.
