由于没有合适的工具调节温度 ,通常很难准确地校准温度传感器。本文所述的参考温度源的目的就在于提供这种便利。由于该参考温度源是可变的 ,因而还可利用参考温度正确地调节恒温箱。该图说明如何利用ＢＤＶ64型功率晶体管 (Ｔ1 )提供恒热源 ,以及如何利用校准的传感器型ＬＭ3
Because there is no suitable tool to adjust the temperature, it is often difficult to accurately calibrate the temperature sensor. The purpose of the reference temperature source described herein is to provide this facility. Since the reference temperature source is variable, the oven can also be adjusted correctly using the reference temperature. This figure shows how to use a BDV64 type power transistor (T1) to provide a constant heat source and how to use the calibrated sensor type LM3
