METHOD OF REMOTE MEASUREMENT OF RELATIVE VALUE OF ACTIVE RESISTANCE OF ELECTRIC CIRCUIT AND DEVICE FOR IMPLEMENTING METHOD Russian patent published in 2008 - IPC G01R27/02 

FIELD: physics.

SUBSTANCE: proposed invention pertains to measuring techniques and can be used in systems for remote control of electric circuits of measuring systems or technological processes during express control of their parameters and evaluation of working capacity of the given objects. The present invention is directed at increasing processing speed of remote measuring of active resistance of an electrical circuit with a capacitor, which provides for constancy of voltage in the controlled circuit. The device for remote measurement of the relative value of active resistance of an electrical circuit consists of a connector line, scaling resistor with a known resistance value, input terminals of the resistance connected to the output of the connector line, a d.c voltage stabiliser, made from an operational amplifier and the output of the transistor cascade. The transistor cascade is equivalent, on parameters and schematic implementation, to the voltage stabilisation cascade, differential amplifier and the computing device or an electronic data processing machine with an input port for analogue information.

EFFECT: described device implements the method of remote measuring the relative value of active resistance of an electrical circuit.
