应用霍尔原理制成的特斯拉计是常用的一种测磁仪器。但由于霍尔传感器的非线性和温度特性使得这种仪器的测量准确度难以提高,目前国内生产的各种指针式或数字式特斯拉计的测量准确度一般部存0.5～2.5%之间。若通过对霍尔传感器进行大量筛选,采用各种模拟电能来减小霍尔传感器的非线性和温度误差,则势必增加线路的复杂性,降低可靠性,使成本提高,调整、使用亦繁琐复杂。
Tesla meter made by Hall principle is a commonly used magnetic measuring instrument. However, due to the non-linearity and temperature characteristics of Hall sensors, the measurement accuracy of such instruments is hard to be improved. At present, the accuracy of various domestic or digital Tesla meters generally ranges from 0.5% to 2.5% . If the hall sensor through a large number of screening, using a variety of analog electrical energy to reduce the Hall sensor nonlinear and temperature errors, it will inevitably increase the complexity of the line, reducing reliability, the cost increase, adjustment, the use of cumbersome .
