摘要
采用高稳定度的激光光源和具有高分辨率、高灵敏度、抗晕光能力强、光动态范围大的CCD(ChargeCoupleDevice)电荷耦合器件,构成激光-CCD糖浆浓度传感器,配以三路脉冲驱动电路、测量电路、单片机系统等,可自动检测被测糖浆的温度和浓度,并对温度变化而引起的浓度变化作自动修正.实验结果表明,测量糖浆浓度的误差为0.3%.
It has been carried out automatically to measure the temperature and concentration of syrup and to correct the syrup concentration caused by the change in temperature with a CCD (Charge Couple Device), is a laser CCD syrup concentration sensor, which is of high stability,resolving power (RP), sensitivity, halo_resistant capability and wide optical dynamic range, together with a three_channel driving circuit, a measuring circuit and a single_chip computer. The experimental results show that the measuring error of syrup concentration is about 0.3%.
