  • Arrangements For Transmission Of Measured Signals (AREA)

Abstract

PURPOSE: To enable measurement signals to be accurately transmitted even in remote measurement of a long transmission distance by constituting a modulation circuit with electronic circuits thereby faithfully reproducing the transient signal changes of the DC measured signals of a pulsation state being outputted from a converter.
CONSTITUTION: This is the remote measurement system of modulating the output obtained via signal level converter from the measuring object with AC signal and remote-transmitting the same, wherein the measurement signal having been converted to DC signal inputs to the terminal IN of the modulation circuit amplidude- controlling the AC signal output by the measured signal, the AC signal inputs from terminal OSC and the AC signal is outputted at the amplitude proportional to the level changes of the measurement signal at the terminal OUT and this turns out that the AC signal from the OSC is outputted after having been amplidude-modulated to the measurement signal waveform from the IN because the DC power source proportional to the measurement signal is applied from the output of the prestage amplifier AMP 1.
