DEVICE FOR CONTINUOUS MONITORING IN TIME OF TOTAL DOSE OF MAGNETIC FIELD WITH 50 HZ FREQUENCY Russian patent published in 2015 - IPC G01R29/08 

FIELD: electricity.

SUBSTANCE: reception antenna is implemented as a three-coordinate sensor allowing to receive the digital signal proportional to a magnetic field parameter. The sensor by its output is connected to the amplifier input which is connected by the output to the frequency filter input, by the output of the processor connected to the input fitted with the special program metering a total actual dose of magnetic field for a certain time interval and its share from a maximum allowable dose, this result from the processor output is displayed, and at achievement of this share of the value equal to one, the signal also goes to the loudspeaker; power supply of the device for continuous monitoring is performed from the battery charged from the power line through the voltage converter. The design of the offered device allows to use it as an individual mobile device for each employee, and provides the metering of magnetic field harmful effects, and also the monitoring of time of allowable influence of magnetic field.

EFFECT: simplification of design of the device of continuous monitoring in time of a total actual dose of magnetic field with a frequency 50 Hz, indication of its level.
