| Abstract: | The principle and design idea of Pt resistance digital thermometer by means of unbalanced bridge are expounded. A method of how to deal with the nonlinear item is suggested. Three experimental approaches of unbalanced bridge consisting of using the resistance box or QJ23 bridge are introduced. |
