用非平衡电桥法设计和组装电子数字温度计

Electronic digital thermometer designed and assembled with nonequilibrium bridge

巧用惠斯通电桥改装成非平衡电桥 ,使用碳膜电阻或铂电阻作为感温元件 ,数字电压表作为显示器 。

Skillfully using Wheatstone bridge to refit into nonequilibrium bridge, the electronic digital thermometer is assembled with carbon film resistor or platinum resistor as the sensitive temperature element and digital voltmeter as the display.
