This article proposed a new thermal conductivity measuring instrument＇ s heating platform based on the FD- TC-B type,using the DS18B20 integration temperature sensor to gather temperature signal,with the system carries on the data processing by AVR microcontroller and union superior machine＇ s edition function module of the LabVIEW softwarethe, the heating platen temperature can be stabl controlled by the PID algorithm. The improved thermal conductivity measuring instrument was realized with automatic data acquisition and processing, real time display temperature curve, data automatic memory and computation, good man-machine contact surface function. This article introduced the design of hardware and software about the device. The experiments show that the improved thermal conductivity measuring device is more reliable, the data is more direct and more accurate. It can meet the research testing and teaching experiments＇ requirement.
