Relevance Currently, vibration of parts of various machines is widely used to increase the intensity and efficiency of technological processes for extracting raw materials and semi-finished products (granulating, drying, dissolving and leaching, extracting, adsorption gas separation, etc.). In other cases, on the contrary, it is necessary to eliminate the harmful effect of vibration on production processes to slow down the movement of units and mechanisms, to damp vibrations in various ways (controlled shock absorption systems, electromagnetic dampers, vibration protection, etc.). For active control of oscillatory processes occurring in these machines, vibration sensors directly connected to them are used. The main element of various vibration sensors is a sensitive element that converts mechanical movement into an electromagnetic signal, which allows it to be further processed. As sensitive elements of electromechanical transducers of vibration sensors for measuring small vibrations of the surfaces of vibration objects, classical strain gauge, magnetoelectric, magnetostrictive, piezoelectric and frequency-pulse elements are used. The design and creation of new vibration sensors with improved metrological characteristics is an urgent task for electrical engineering and electromechanics. In this work, the basic formulas and graphs of the experimental output data of the metrological characteristics of the new design of the vibration sensor are obtained. Aim of research To investigate the metrological characteristics of a new design of a conical spiral vibration sensor. Research methods To determine the oscillatory processes, the methods of the theory of electrical circuits, magnetic fields, methods of mathematical analysis and the theory of electrical oscillatory processes in (beats, induction, etc.) folded circuits are used. Results A new design of a conical spiral vibration sensor has been developed and its metrological characteristics have been investigated.
