The present invention provides a load cell which, if respective sensor portions positioned along the vertical direction through a main body are strained by means of an external force and the resistance changes, derives the strain from the changed resistance and measures the size and location of the external force from the derived strain. Therefore, if respective sensor portions positioned along the vertical direction through a main body are strained by means of an external force and the resistance changes, the strain from the changed resistance is derived and the size and location of the external force can be measured from the derived strain. La présente invention concerne une cellule de charge qui, si des parties de capteur respectives positionnées le long de la direction verticale à travers un corps principal sont sollicitées au moyen d'une force externe et que la résistance change, dérive la contrainte à partir de la résistance modifiée et mesure la taille et l'emplacement de la force externe à partir de la contrainte dérivée. Par conséquent, si des parties de capteur respectives positionnées le long de la direction verticale à travers un corps principal sont sollicitées au moyen d'une force externe et que la résistance change, la contrainte provenant de la résistance modifiée est dérivée et la taille et l'emplacement de la force externe peuvent être mesurés à partir de la contrainte dérivée. 본 발명은 본체의 상하 방향을 따라 관통되어 배치되는 각각의 센서부들이 외력에 의해 변형되어 저항이 변화되면, 상기 변화된 저항으로부터 스트레인을 도출하고, 상기 도출된 스트레인으로부터 외력의 크기 및 위치를 측정하는 로드 셀 을 제공한다. 따라서, 본체의 상하 방향을 따라 관통되어 배치되는 각각의 센서부들이 외력에 의해 변형되어 저항이 변화되면, 상기 변화된 저항으로부터 스트레인을 도출하고, 상기 도출된 스트레인으로부터 외력의 크기 및 위치를 측정 가능하다.
