Abstract
An electric-induction cylindrical electric field strength sensor is considered. The aim of this work is to investigate the interaction of a cylindrical sensor with an inhomogeneous electric field of a linear charge in order to determine the parameters of a sensor that affect its error in an inhomogeneous field. Optimization of the set parameters allows creating sensors with known guaranteed metrological characteristics and having an additional error from the inhomogeneity of the field no more than 3% in the spatial range from 0 to 3R to the source of the field. As a result of the study, the formula for estimating the error of a cylindrical sensor caused by the inhomogeneity of the electric field both from its angular and linear dimensions and from the spatial measurement range was obtained for the first time. The range of application of such high-precision sensors of electric fields is wide. They can be used both in production processes and in various areas of society.
