FIELD: electric engineering.
SUBSTANCE: device has electrical pathway for measuring current intensity, Hall probe provided with amplifier and comparator, power supply source and analog-to-digital converter having three units for comparing signal and three reference voltage sources. Hall probe output having the amplifier and comparator is connected to the second outputs of the first and the second input of the third unit for comparing signal. Output of the first reference voltage source is connected to the first input of the first unit for comparing signal. Output of the second reference voltage source is connected to the first input of the second unit for comparing signal. Output of the third reference voltage source is connected to the second input of the third unit for comparing signal.
EFFECT: wide range of functional applications.
