一、多圈线绕电位器及线性精度多圈线绕电位器在电讯、电工、电子仪器、计算机和自动控制系统中有着广泛应用,用于精密调节直流及低频电压、电流。因此多圈电位器的线性精度是它的重要参数之一。所谓线性就是电位器输出电压与转轴行程之间的函数关系呈直线的特性。电位器实际直线性与理论直线之间的最大偏差就称为直线性偏差。习惯称为线性精度,通常以总外加电压的百分数表示,而线性又根据理论直线的展开行程的不同
A multi-turn around the potentiometer and linearity accuracy Multi-turn around the potentiometer in the telecommunications, electrical, electronic equipment, computers and automatic control system has a wide range of applications for precision regulation of DC and low-frequency voltage and current. Therefore, the multi-turn potentiometer linear accuracy is one of its important parameters. The so-called linear is the potentiometer output voltage and shaft travel as a linear relationship between the characteristics. The maximum deviation between the actual linearity of the potentiometer and the theoretical straight line is called linear deviation. Custom is called linear accuracy, usually expressed as a percentage of the total applied voltage, and the linearity is based on the theoretical straight line
