为了提高力传感器性能,1978年中国计量科学研究院传感器组研制成镀铜和镀金端子聚(月先)亚胺箔式应变片各一种(图1);以及传感器用零点平衡补偿电阻片和零点温度补偿电阻片(图2);传感器系数补偿电阻片(图3),系数的温度补偿电阻片(图4);四种补偿片均为镀铜端子片。镀层端子应变片主要优点是: In order to improve the performance of the force sensor, in 1978 the China Metrology Institute sensor group developed into a copper-plated and gold-plated terminal (month) imine foil strain gauge one (Figure 1); and sensor zero balance compensation resistors and Zero temperature compensation resistor chip (Figure 2); sensor coefficient compensation resistor chip (Figure 3), coefficient of temperature compensation resistor chip (Figure 4); four kinds of compensation films are copper terminal pieces. The main advantages of coated terminal strain gauge are:
