FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment and can be used in remote control systems of resistance of resistor sensor. Group of inventions is a device for remote conversion of resistance of a resistor sensor into direct current voltage, comprising a direct current source, a long two-wire connecting line, a resistor sensor, first and second amplifying elements, an adder with two inputs, a controlled DC additional voltage source, a zero indicator and a method for use thereof.
EFFECT: high accuracy and sensitivity of the process of converting resistance of the resistor sensor to direct-current voltage.
