BRIDGE MEASURING DEVICE FOR PARAMETERS OF N-ELEMENT TWO-TERMINAL NETWORKS Russian patent published in 2018 - IPC G01R17/10 

FIELD: measuring equipment.

SUBSTANCE: invention relates to instrumentation, automation and industrial electronics and can be used to monitor and determine the parameters of measurement objects, as well as physical quantities through parametric sensors. Device consists of measuring bridge, zero-indicator, signal generator. Claimed generator consists of four pulse shapers, synchronization unit, switchboard and power amplifier. Generator has three outputs – synchronization output, grounding, signal output. Zero-indicator has two inputs, a ground terminal, a synchronization pin. Bridge circuit consists of two branches. First branch contains two resistors, the second branch contains a resistor and terminals for connecting the measurement object. Inverse measurement objects can be used. Two types of chain are introduced in the bridge. Above is a build-up chain consisting of a capacitor, an inductor, four resistors. Below is a build-up chain, consisting of a capacitor, two resistors, an inductor. Sum of the number of elements in all chains of a second type of growth and the second resistor in the first branch is equal to the number of parameters in the two-terminal network of the measurement object.

EFFECT: technical results are the combination of two important properties in one LCR bridge of two-terminal network parameters and separate balancing of the bridge circuit with only adjustable resistors, and expansion of functionality.
