摘要：A PC-based data acquisitionlmeasurement system has been presented for the thermal conductivity of snow, using thermal probe. The thermal probe is a transient method of thermal conductivity measurement and has advantages in terms of short-run time, smaller temperature rise, and in situ measurement applications. The developed data acquisition system does intelligent mana-ge ment of different sensors for thermal conductivitv,.. and is based on RS-232 serial communication with RS-485 data conversion, providing additional advantage of long-distance measurement in field conditions. The hardware and software features of the system are described and its performance for different materials along with test results, is presdnted.
