    • A force measuring apparatus comprises a force-transmitting component, on which a strain measuring element is held, which comprises a carrier element and a displacement transducer. The carrier element has two fixing sections at a predefined distance from each other in the direction of the strain with which it is fixed to the component. Furthermore, the carrier element has a strain section, which is provided between the fixing sections and which has a shorter length in the direction of the strain than the distance between the fixing sections and which has a smaller cross section than the remaining carrier element. The displacement transducer is connected to the strain section in order to register the strain of the strain section.
    • 力测量装置包括力传递部件,其上保持有应变测量元件,其包括载体元件和位移传感器。 载体元件具有两个固定部分,该固定部分在其被固定到部件上的应变方向上彼此预定距离。 此外,载体元件具有应变部,该应变部设置在固定部之间,并且在应变方向上具有比固定部之间的距离更短的长度,并且其截面比剩余的载体元件小。 位移传感器连接到应变段,以便记录应变段的应变。
