| 摘 要： | 半导体温度传感器具有较高的精度和良好的线性输出。采用LM135型半导体温度传感器,与CPU、数码管接口,经A/D和V/F转换等信号处理,成功研制了某直升飞机数字大气温度显示器,取代了双金属片指针式温度计。试验结果表明LM135传感器在-55℃～70℃可以实现单点校准,在-60℃～-55℃出现非线性,可以通过程序进行单点补偿校准。

| Abstract: | Using LM135 semiconductor temperature sensor, CPU and digital tube interface, a digital display free air thermometer for helicopters has been developed sucessfully, which will take the place of the bimetal pointer thermometer. It has been known from the tested results that the LM135 semiconductor temperature sensor has achieved the single shot calibrated in -55℃~70℃, and the nonlinearity in -55℃~60℃ can be calibrated by single shot compensation calibration. |
