传感器是自动化控制中重要部件之一,它的精度直接影响过程控制的精度。影响传感器精度的因素很多、其中最主要的是传感器的零点误差、零点漂移、非线性误差、温度漂移及供电直流稳压电源稳定度等因素。为提高传感器的精度,采用下列方法消除上述诸影响因素。一.消除传感器零点误差和零点漂移的两种方
Sensor is one of the most important parts of automation control, and its accuracy directly affects the accuracy of process control. Many factors affect the accuracy of the sensor, of which the most important is the sensor zero error, zero drift, nonlinear error, temperature drift and power supply stability of DC power supply and other factors. To improve the accuracy of the sensor, the following methods are used to eliminate the above-mentioned influencing factors. One to eliminate the sensor zero error and zero drift of two parties
