SYSTEMATIZATION OF MEASUREMENT DEVICES ACCORDING TO METHOD OF MEASUREMENT OF MECHANICAL VALUES AND PRINCIPLES OF THEIR IMPLEMENTATION

A physical phenomenon or the effect underlying the measurement is called the measurement principle. For example, applying the Josephson effect to measure the electrical voltage or the Doppler effect for measuring speed. To perform measurements, select a certain measurement method – the reception or a set of methods for comparing the measured physical quantity with its unit in accordance with the realized measurement principle. In this paper, we investigate instruments and methods for measuring mechanical quantities in wireless sensor networks and digital measuring devices that are connected to nodes of sensor networks and together constitute an information measuring system. The problem of measuring the distance and transit time of a signal between transceivers is being investigated. The distance is calculated using the propagation time of the signal.
