Abstract:In order to realize automatic verification of industrial thermal resistance and improve test efficiency and accuracy of value transfer,an industrial thermal resistance automatic verification system is designed.According to the thermal resistance verification principle and idea of automatic verification,the system hardware structure and the operation steps of calibrating system are described.System uses the temperature measuring bridge and low potential scan switch,the automatic conversion of line connection method from two to three can be realized in industrial platinum resistance verification.As a development platform,VB is used to achieve automatic temperature control,data acquisition and output word statements in operating system software.The practical application shows that the system has the advantages of reasonable structure,convenient software operation,accurate and reliable value transfer.
Keywords:Automatic verification system Temperature controller Serial communication Data acquisition Platinum resistance
