基于热电偶反馈的温度控制需要对传感器的非线性进行补偿。人为的办法是常使用毫伏一温度校正表。实现自动补偿的方法可以采用非统一的校正标尺以及数字式或模拟式线性化电路。然而后者需要有非线性电位器,这种电位器绕制得以使由动片的等量位移引起的电阻变化相应于温度的等量增量引起的热电势变化。在采用两个同时调节的线性电位器的网络中,这些特殊绕制的元件可以避免。这种电路是为了适应热电偶的使用而发展起来的,但它也能容易地被采用于非线性输出近似为抛物线
Temperature control based on thermocouple feedback requires compensation of the sensor’s non-linearity. Man-made approach is often used millivolt temperature correction table. The method of automatic compensation can use non-uniform calibration scale and digital or analog linearization circuit. However, the latter requires a non-linear potentiometer which is wound so that the change in resistance due to the equivalent displacement of the rotor corresponds to a change in thermoelectric potential due to an equal increment of temperature. In networks that use two simultaneously regulated linear potentiometers, these specially wound components can be avoided. This circuit has been developed to accommodate the use of thermocouples, but it can also easily be applied to non-linear output approximating a parabola
