APPLICATION OF VIRTUAL INSTRUMENTATION IN DETERMINING THE TEMPERATURE FIELDS OF HOT ROLLING CYLINDERS

The paper presents a LabVIEW application to determine the voltage-temperature characteristic of a thermocouple Pt-Rh/Pt. Using virtual instrumentation and LabVIEW graphical programming environment, to determine the temperature field of hot rolling cylinders allows replacement measurement systems consist of conventional devices with simple tools more precise and at a price much lower cost. Understand changes in temperature of hot rolling cylinders is required to study the phenomenon of thermal fatigue in these machine parts. Thus, a signal adapter, a computer and a printer will be able to perform accurate experimental determinations with incomparable precision measuring classics devices.
