Dual spherical intensity sensors for new generation low-frequency electric fields

Abstract

These electric fields adversely affect the environment, technical and biological objects. In this regard, it is necessary to control the levels of electric fields, an important characteristic of which is the strength of the electric field. Sensors of the electric field strength are required to sense the electric field. The existing sensors are inconvenient in operation and have a high error in the perception of the electric field strength, reaching +- 20 %. In the work under consideration, the idea of creating a universal sensor of a new type, related to the type of dual sensors, is put forward. Its versatility lies in the fact that it embodies all types of known sensors — single, double, and now twin. The error in the perception of the intensity of the inhomogeneous electric field of the dual sensors does not exceed + 5 % in the entire spatial measurement range 0a1. In this case, the distance d to the field source is limited only by the radius of the spherical base of the sensor, i.e. d  R. At the same time, for sensors that are part of a dual sensor in the same spatial measurement range, the error is +- 35 %. Using a dual sensor, it is possible to achieve a significant increase in the accuracy of measuring the strength of inhomogeneous electric fields in a wide spatial measurement range in comparison with known sensors.
