数显恒温控制器电路设计

Digital Display Constant Temperature Controller Circuit Design

用晶体管的 PN 结作温度传感器,用双向可控硅作无触点控制开关,用 ICL7135作 A/D 转换器等,制作了数显恒温控制器。

The article gives a full exposition of a digital display constant temperature controller by using transistor PN junction as temperature sensor, two-way silicon controlled rectifier as non-contact control switch and ICL7135 as A/D converter.
