用晶体管来制作电子温度计具有测温范围宽、灵敏度高、非线性小、价格低等优点。它是测温领域内待开发的一种敏感元件。关键在于怎样解决线性化和传感器一探头能否互换的问题。本文从硅晶体管测温的物理方程出发,论述如何推求管子的能带间隙,它与线性、互换性之间的关系,导出了晶体管的实际测温方程,由此研制出了精密晶体管数字测温仪。同时,按照本文论述的原理,可以求出晶体管的能带间隙的平均值,用来检查晶体管制造的内在质量。新颖的线性校正电路,还能校正某些具有指数特性的敏感元件。
Transistor to produce electronic thermometer with a wide temperature range, high sensitivity, low nonlinearity, low price and so on. It is a sensitive component to be developed in the field of temperature measurement. The key is how to solve the problem of linearization and sensor-probe interchangeability. In this paper, starting from the physical equation of silicon transistor temperature measurement, this paper discusses how to deduce the band gap of the tube, its relationship with linearity and interchangeability, and deduces the actual temperature measurement equation of the transistor. Wen Yi. At the same time, in accordance with the principles discussed in this article, you can find the average transistor band gap can be used to check the inherent quality of transistor manufacturing. Novel linear correction circuit, but also to correct some of the sensitive components with exponential characteristics.
