BRIDGE CIRCUITS WITH BALANCING BY ADJUSTABLE RESISTORS IN DEVICES OF CONCENTRATION AND PRIMARY PROCESSING OF INFORMATION FOR CONTROL SYSTEMS

There the determination manner of characteristics of multimember two-terminal networks with use of bridge circuits which are energized by pulses with voltage change in their duration according to the power function law as well as the devices of concentration and primary processing of information for the control systems on the basis of bridge circuits have been studied. The groups of bridge circuits with the pulsed power and with the separate balancing by adjustable resistors only to determine the indicators of objects with uniform and non-uniform reactive members accordingly in three-member system of substitution as well as to find the resistance of two or three resistance transducers in one bridge circuit have been developed. The new property of mathematical expressions of determined structure on the basis of equation roots has been brought out. The mathematical simulator of bridge circuits to be energized by complex-form pulses has been constructed. The data base for all considered bridge circuits has been formed. The determination technique of sensitivity of bridge circuits to be energized by complex-form pulses has been created. The specialized device of primary processingg of information has been developed on the basis of bridge circuits with pulsed power has been developed. The device to control the level of free-flowing substances and the laboratory rig for determination of characteristics of three-member two-terminal networks have been developed and have been introduced. The developed bridge circuits and the devices on their basis have been oriented for application in the device of concentration and primary processing of information for the control systems of diverse industrial purposeAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
