| Summary: | Measuring the parameters of electric fields affecting technical and
biological objects is impossible without the use of electric field
strength sensors. Accurate measurement and control of electric
field strength levels is challenging. This is due to the fact that
the intensity is a vector quantity, characterized not only by the
modulus, but also by the direction. The existing wide variety of
strain gauges of various shapes (cubic, cylindrical, spherical), the
principle of action (directional and non-directional reception)
and design features (case, bodyless) do not provide the desired
metrological characteristics. Therefore, the work related to the
development of electric field strength sensors does not stand still
and is relevant. The aim of the study is to create a frameless threeaxis sensor of electric field strength, the calculation of which
would be simple as for the case, and the simplicity of design and low weight as for the frameless sensors. The sensor created as a
result of research is structurally represented by three mutually
perpendicular dielectric disks, the bases of which are conducting
sensitive elements. The sensor depending on the desired error has
a different spatial measurement range and the larger the error,
the wider the range. For a measurement error not exceeding
10 %, the maximum possible spatial measurement range will be
a = 0,4. Therefore, the minimum possible distance to the field
source, at which the sensor error does not go beyond 10 %, will be
d = 2,5R, where R is the radius of the sensor disk. |
