Title (EN) TRANSDUCER FOR CONVERTING A VARYING ANALOG CURRENT SIGNAL TO A BINARY DIGITAL SIGNAL
(FR) TRANSDUCTEUR DE CONVERSION D"UN SIGNAL DE COURANT ANALOGUE VARIABLE EN UN SIGNAL NUMERIQUE BINAIRE
Abstract: front page image
(EN)A digital output capacitive transducer wherein two capacitors (C1, C2) are used, one (C2) providing a reference current and the other providing a varying signal current. The signal current is obtained from an oscillator (10) through a capacitor (C1), which varies in capacitance as a function of the parameter to be measured. The reference current offsets the signal current to attain a known relationship between the sampled parameter and the signal current. The circuit has a small number of components and operates on a relatively low voltage with an accurate digital output.
(FR)Un transducteur capacitif a sortie numerique utilise deux capaciteurs (C1, C2), dont l"un (C2) produit un courant de reference et l"autre produit un courant de signal variable. Le courant de signal est obtenu a partir d"un oscillateur (10) a travers un capaciteur (C1), dont la capacitance varie en fonction du parametre a mesurer. Le courant de reference decale le courant pour obtenir une relation connue entre le parametre d"essai et le courant de signal. Le circuit possede un petit nombre de composants et fonctionne avec une tension relativement basse et une sortie numerique precise.
