| Abstract: | In vacuum and low temperature system,thermodynamic properties measurement of the superconducting material is the basic study of the Cryogenics.In order to meet the requirement for real-time,continuous and accuracy superconducting material thermodynamic properties data acquisition,also to realize the integration of multiple instruments and data acquisition,the vacuum and low temperature data acquisition system was designed based on LabVIEW virtual instrument.Through the data analysis,we found that the vacuum and low temperature measurement system has good stability,data acquisition is continuous,intuitive and accurate.It will provide a new method for obtaining the accurate measurement of low temperature and vacuum parameters. |
