BRIDGE MEASURING DEVICE FOR MEASURING PARAMETERS OF TWO-TERMINAL CIRCUITS Russian patent published in 2016 - IPC G01R17/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to instrumentation, automation and industrial electronics, in particular, it enables to determine parameters of four-element bipoles or parameters of sensors with a four-element equivalent circuit. Bridge meter of bipole parameters comprises a generator of feed pulses, additional capacitor and an integrator. In first branch of bridge circuit additional capacitor is connected in parallel to first resistor, common output of first resistor, capacitor and additional capacitor of first branch of bridge is connected with free terminal of single resistor of second branch, said common lead is grounded, and common lead of single resistor of first branch of bridge and second terminal for connection of bipole of measuring object of second branch is connected to first output of generator of feed pulses. Output of rectangular pulse generator is connected not only with corresponding input of switch, but also with input of ramp voltage pulse generator, output of which is connected not only with corresponding input of switch, but also to input of integrator, output of which is connected to input of cubic pulse generator, output of latter is connected not only with corresponding input of switch, but also with input of pulse shaper with variation of voltage according to law of fourth degree of time.

EFFECT: technical result consists in reduction of measurement error.
