    • A load sensor comprises a load detecting element and a temperature compensating element. The load detecting element is made of the material and acting the load thereon. The temperature compensating element is made of the same material with the load detecting element, and made as the same dimension or similar figure with the load detecting element. The load detecting element and the temperature compensating element are arranged closely each other. Further, each of the load detecting element and the temperature compensating element comprises conductive part which is made of the same composite. The conductive parts of the load detecting element and the temperature compensating element are electrically connected to a power source in parallel each other. Difference between voltages which act on the conductive parts of the load detecting element and the temperature compensating element is detected as a equivalent of the load.
    • 负载传感器包括负载检测元件和温度补偿元件。 负载检测元件由材料制成并对其施加负载。 温度补偿元件由与负载检测元件相同的材料制成,并且与负载检测元件形成为相同的尺寸或类似的图形。 负载检测元件和温度补偿元件彼此紧密地排列。 此外,负载检测元件和温度补偿元件中的每一个包括由相同复合材料制成的导电部件。 负载检测元件和温度补偿元件的导电部件彼此并联地电连接到电源。 作为负载检测元件的导电部件的电压和温度补偿元件之间的差异被检测为等效于负载。
