摘要
热敏型红外传感器被用在温度一维分布测量系统中 ,使用时将传感器接入由数字电位器及电阻器组成的电桥中。通过单片机直接控制数字电位器 ,实现了传感器零位的自动跟踪 。
The infrared thermistor transducer is used in one dimension system of temperature measurement,the transducer is connected into the electric bridge that is composed of resistors and digital potentiometer.The single chip processor can control digital potentiometer to trace the zero point of transducer,so the problem of the direct shift of transducer is solved successfully.
