| Summary: | The article provides a comparative analysis of multi-element
sensors of an electric field of a flat shape differing in various
configurations of sensitive elements, each of which is determined
by its design parameters. For this, a generalized mathematical
model of the sensor is compiled taking into account its design
parameters which affect the error from field inhomogeneity
and the spatial range of measurement. Using a generalized
mathematical model, graphs of the sensor error are constructed
depending on the spatial measurement range and various design
parameters of its sensitive elements. The change in design
parameters allowed us to model sensitive elements in the form of
quadrants and truncated quadrants of a circle. According to the
error graphs, it is established that sensitive elements made in the
form of quadrants of a circle provide the sensor with a lower error
and a larger spatial range of measurement, therefore their use is
more appropriate. The studies performed allowed us to obtain the
following technical results. Sensors with sensitive elements in the
form of a quadrant of a circle have a minimum of an error and a
maximum of a spatial range of measurement at design parameters: b = 0 and b0
= 0,2; b = 0 and b0
= 0.4, for which, with a
maximum spatial range of measurement equal to unity (a = 1),
the errors are respectively minus 3 % and minus 10 %. |
