Designing of Thermistor Digital Thermometer Based on Unbalanced Electric Bridge

Article Preview

Abstract:

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.
