Intelligent Thermal Expansion Testing Applications Developed

Intelligent Measuring not only develops examining, testing and controlling technology, but also an important tool in application and study of material science. Application system of intelligent thermal expanding measuring sets up the plat of intelligent measuring based in thermal expanding measuring application. When the system is used to measure thermal expanding, it adopts highly accurate differential transformer as expanding-magnitude signal sensor, examines the displacement and temperature through data acquisition system, examines if data get into database and are stored, and make data process by many tasks. Applying procedures are based on PC window procedure, adopt C++ Builder 6.0 compiling and have a simply friendly surface and a strong function of database. The temperature controlling procedure involves the ideas of fuzzy control and data fusion. The system consists of the functions that are the measure of thermal expanding magnitude, instant-temperature measure and multi-point temperature testing which supplies a strong tool for studying material science; the system can measure temperature changing in the process of electrical pulse heating which is used in studying character of electrical pulse heating.
