System for test and verification of the thermostat from automobile cooling system

This paper presents a PC-based system for test and verification of the thermostat from automobile cooling system. The application measures the displacement of thermostat valve as a function of temperature. Measurement data are plotted and stored then in a file. The application was developed in LabVIEW; the most used graphical language for virtual instrumentation. For measurement and data acquisition it was used a module from I-7000 series, made by ICPDAS, which have great performances and are very easily to use. By combining the performances of these modules with the great flexibility and stability of LabVIEW programming language, it can be designed measurements system that assures a very good accuracy, stability and reliability, with a low cost.
