Abstract
(EN) A sensor circuit (3) comprises: a detection resistor connected to a wiring (23); a first terminal pair (31) constituted from terminal wirings connected respectively to both end parts of the detection resistor; a second terminal pair (32) constituted from terminal wirings shorted with each other in one end part of the detection resistor; and a sensing unit (33) for measuring an electric current or a voltage from which a noise component has been removed, using a detection signal inputted through the first terminal pair (31) and a detection signal inputted through the second terminal pair (32).
(FR) Un circuit de capteur (3) comprend : une résistance de détection connectée à un câblage (23) ; une première paire de bornes (31) constituées de câblages de borne connectés respectivement aux deux parties d'extrémité de la résistance de détection ; une seconde paire de bornes (32) constituées de câblages de borne court-circuités entre eux dans une partie d'extrémité de la résistance de détection ; et une unité de détection (33) pour mesurer un courant électrique ou une tension à partir de laquelle une composante de bruit a été éliminée, à l'aide d'un signal de détection entré par l'intermédiaire de la première paire de bornes (31) et un signal de détection entré par l'intermédiaire de la seconde paire de bornes (32).
(JA) センサ回路(3)は、配線(23)に接続された検出用抵抗と、検出用抵抗の両方の端部にそれぞれ接続された端子配線によって構成された第1の端子対(31)と、検出用抵抗の一方の端部において互いにショートされた端子配線によって構成された第2の端子対(32)と、第1の端子対(31)を通じて入力された検出信号と、第2の端子対(32)を通じて入力された検出信号とを用いて、ノイズ成分を除去した電流または電圧を測定するセンシング部(33)を備える。
