The aim of the invention is to improve the accuracy of measurements by reducing the level of synchronous interference from the uninterrupted supply voltage.

The drawing schematically shows an example of a specific polyphenine meter electric field of the atmosphere.

The atmospheric electric field meter contains an underwater synchronous electric motor 1 (for example) and a reference voltage coupled to the axis of the electric motor of generator 2 (in this case, electromagnetic type with two pairs of magnetic poles, and 2) and a PO / 1Ya sensor, 1 10 fixed stationary measuring electrode 3 (round a metal plate), reinforced on the axis of the electric motor 1. rotate 1, screen 1, 1st elec- K gen I (plrstine with black and asthmi.

The device operates as follows.

In the presence of field E and rotation of the shield electrode 4, as a result of modulation of the field, an alternating voltage is generated at the measuring electrode 3 and at the input of the alternating voltage amplifier b

y with a frequency of Hz, the amplitude of which is proportional to the field strength E (and the number N), and the phase depends on the sign of the field.

-lacroTa of the reference voltage taken from the electromagnetic generator 2 and

arriving at the synchronous detector 7 is equal to Hz. In this case, the interference voltage with a frequency of Hz, being the even harmonic of the reference voltage with a frequency of Hz, is almost completely suppressed by the synchronous detector. Thus, the interference product at the output of the synchronous detector is practically zero and there is only a useful signal whose frequency is fc 3fo
