LINEAR DISPLACEMENT TRANSDUCER

摘要

FIELD: instrumentation.SUBSTANCE: invention relates to instrumentation to be used for high-precision contactless measurements in geodesy and construction. It is composed by linear displacement transducer consisting of two radio signal sources, two radio signal receivers, two time interval metres and analysis and indication means. Smooth modulation generator and time attribute generator defining signal individual attributes are mounted at input of every said source. Signal of every source arrives to inputs of every receiver. Inputs of time interval appropriate metre are connected via two channels to outputs of every receiver. Each of the latter comprises smooth modulation generator and time attribute generator defining signal individual attributes. Note here that output of smooth modulation generator is connected with input of time attribute generator defining signal individual attributes its output doubles as the signal processing channel output. Every time interval metre has its output connected to appropriate input of analysis and indication means.EFFECT: higher precision.3 cl, 5 dwg
