PURPOSE:To furnish the converting device not requiring adjustment by a method wherein the output of an oscillator whose frquency changes according to displacement and power is converted into a pulse signal corresponding to a weighting quantity indicated by waveform area and cycle of repetition and later is averaged. CONSTITUTION:The oscillator is constituted by a vibrator V whose resonant frequency changes according to powers P1 and P2 and by an exciting part EX and the output A thereof is converted into the pulse signal B corresponding to the weighting quantity indicated by the waveform area and the cycle of repetition in a weight setting part WS, and a DC output C corresponding to an averaged value is obtained in an averaging circuit AV. In an output part OU, the output C is converted into the change in a current transmitted to a power source B and a load resistance RL. |
