Dan Zhang, Ming Ji Shi, Lan Li Chen, Shu Juan Ding · Key engineering materials · 2013
The temperature measure principle of unbalanced electric bridge is expounded by means of temperature characteristics of thermistor. A method to deal with nonlinear function is proposed. The experiment indicts that the thermistor digital thermometer based on unbalanced electric bridge is in accordance with the design request. Its circuit is simple and it has certain practical value.
