| Abstract: | We have designed an automatic instrument of temperature measurement and control.In this instrument,a semconductor triede is use.d as the temperature sensor,while an ingegrated circuit operational amplifier as the mesurement and control divice.This instrument is simple in structure,accurate,quick,and reliable in measurement,and low in price.It would be applicable to rnany related physical and chemical exporiments in Colleges and Schools. An application is presented in this paper as an example for the measurements of the linear expansion coefficient of metal,which is a standard experiment in College physics education. |
