BRIDGE METRE OF PARAMETRES OF TWO-TERMINAL DEVICES Russian patent published in 2009 - IPC G01R17/00 

FIELD: measurement equipment.

SUBSTANCE: invention refers to instrumentation equipment, automation and industrial electronics, namely it allows determining parametres of three-element two-terminal devices or parametres of sensors with three-element equivalent circuit. Bridge metre of parametres of two-terminal devices includes in-series connected generator of compound feeding electric signal, bridge circuit and null indicator. New feature of bridge metre of two-terminal devices parametres is introduction to two-terminal device with balancing elements, which is included in bridge circuit, of additional second capacitor which is parallel connected to available circuit from in-series connected first capacitor, first resistor and first inductivity, as well as additional second resistor which is parallel connected to available circuit from in-series connected first resistor and first inductivity; at that, three of five functional elements of two-terminal device with balancing elements are adjustable, and functional elements of two-terminal device of measuring object serve as unknown quantities of three parametres - first capacity, first resistor and first inductivity.

EFFECT: simplifying and speeding up measurement.
