本例描述了一个用于电路问题诊断(如过热元件和热失控)的双晶体管热探针。虽然探针并不能提供精确的温度测量,但可以用探测二极管简单地试探某个可疑元件,从而对潜在的热问题做一次速检。电路包括指示表,可以一起装入一个小外壳内,如一个空的20g胶棒管。 This example describes a dual transistor thermal probe for troubleshooting circuit problems such as overheating components and thermal runaway. Although the probe does not provide accurate temperature measurements, a probing diode can be used to simply probe a suspect component for a quick test of potential thermal issues. The circuit includes an indicator that can be put together in a small enclosure, such as an empty 20g glue tube.
