  • Independent modules






Introduction

This comprehensive experimental apparatus consists of a control unit and independent functional modules. The control unit integrates measurement and display units for parameters such as temperature, pressure, voltage, and current with high-precision long time timing unit, PID control and manual control unit, multiple sets of DC power supply unit, and four-way sensor interface unit. Each functional module is specifically designed for a set of particular experiments (at present, there is only one module available and more modules will be added when they become available).

 

Using the control unit and module # 1, the following experiments can be performed:

 

(1) PID applications

(2) Heat conductive coefficient measurement of a poor conductor

(3) Heat conductive coefficient measurement of air

(4) Heat conductive coefficient measurement of a metal

(5) Specific heat capacity measurement of a metal

(6) Linear expansion coefficient measurement of a metal
