Description

The utility model relates to the field of measurement technology and is intended for rapid measurements in the field, in various geological environmental conditions, different climatic zones, at different times of the day and in different weather. And also with the help of this device, it is possible to carry out measurements in residential and working rooms of biologically dangerous levels of electrostatic fields, the sources of which are electrical installations, etc.

The electrostatic field strength meter SU983586A1 is known from the prior art, published on 12/23/1982. However, this meter does not contain a USB port and a Wi-Fi wireless data transmission module for connecting to a personal computer and other computers, which significantly complicates the work of operators (geologists) in the field, outdoors.

The technical result of the utility model is the creation of a device for measuring the strength and potential of the electrostatic field that allows you to receive data at high speed and transfer the data obtained from the measurements to a personal computer and other computers.

The claimed device contains a remote antenna, a housing with a matrix display, inside of which there is a power supply unit, a microelectric motor, an electrostatic field strength converter unit, a control unit, an analog-to-digital converter (ADC), a central board with a microprocessor containing internal memory (ROM), a wireless module Wi-F data reception and transmission and USB port, displayed on the outer surface of the device. The USB port may have a USB 2.0 or USB 3.0 specification.

The tension converter block consists of a modulator representing a metal plate in the form of a petal, asymmetrically fixed to the axis of rotation of the microelectric motor. The ADC unit is connected to the central board and the control unit via connectors. The power supply unit is electrically connected to the voltage converter unit, the control unit and the central board. When connecting the device to the computer via the USB port, it is possible to calibrate the device using special software installed on the computer, as well as transfer the data received during the measurement process. It is also possible to transfer data from the device to the computer using the Wi-Fi module. These features allow you to calibrate the device and transfer data to a computer directly in the field, which greatly simplifies the work of specialists involved in measuring the potential of the electrostatic field and intensity.

The principle of operation of the device.

When the modulator petal rotates in an electrostatic field, the potential of the modulator petal relative to the earth changes according to a sinusoidal law with a frequency equal to the rotational speed of the petal, and the amplitude of this variable potential is proportional to the projection of the electrostatic field strength on the plane of rotation. The variable potential is transmitted to the ADC and then processed by the microprocessor. The data processed by the microprocessor is stored in the device’s internal memory and, if necessary, is transferred to the computer via a USB port or Wi-Fi module.
