摘　　要：温度测量在工业应用和科学研究中应用较广,通常需要测量多路温度信号。AD595是K型热电偶的放大器,具有冷端补偿、低阻抗电压、断线报警的特点。基于AD595,结合多路选择开关和数据采集卡,设计了多路测温系统,并在计算机上编写程序,实现了多路温度传感器信号的采集。Multi - path temperature measurement is widely applied in industry and research. AD595 is a amplifier for K type thermocouple, and has cold junction compensation, low voltage impedance and wire break alarm. A multi - path temperature measuring system was designed with AD595, multiplexer and data acquisition board. By computer, multi - path temperature sensor signals are acquired.
