| Summary: | Tasks related to the protection of biological and technical objects from the effects
of electrical are relevant. One of these tasks is related to the development of
electric field strength sensors with specified metrological characteristics. The aim
of the study is to minimize the error of the known sensor and expand its spatial
measurement range due to the rational choice of sensitive elements. The sensor
proposed in the work has a negative error from the field inhomogeneity modulo
no more than 3 % in the spatial measurement range 0aR, where R is the radius
of the disk base of the sensor. To ensure the required metrological characteristics
of the sensor, rational dimensions of its sensitive elements are selected. In this case,
the rational radius r of the sensing elements made in the shape of a circle must
satisfy the condition r<R, i.e. it must be less than the radius R of the disk base of
the sensor. If this condition is met, a smaller radius r of the sensing element will
correspond to a smaller error from the inhomogeneity of the field and a larger
spatial measurement range. In comparison with known sensors, with the same error,
the proposed sensor has a spatial measurement range approximately five times
larger. This approach to the selection of sensitive elements allows us to design
sensors with the best metrological characteristics. |
