| Abstract: | The computer-aided system for measuring the apparent heat conductivity of insulated tubings is used to evaluate theinsulating property of insulated tubings. According to the principle of steady-state measuring, by means of electric heatingand by the programmed variable gain PID control algorithm, the apparent heat conductivity of the system in heat-banlancestate at the setting temperature is worked out.The measuring principle, hardware and software of the system areintroduced. The system has been applied to field measuring, and good effects are achieved. |
