| 摘 要： | 数字式测温仪表已成为自动化生产过程中最为普通的仪表，但工业用数字测温仪表在某些场合受到限制，特别是在测量精度方面．作者研制了多种高精度数字测温仪表，经过一年运行后，复测仪表精度，误差不超过上０．１℃，许多点的重复性在０．０３℃内．本文着重论述测温传感器的选择，铂电阻的非线性校正，Ｒ—Ｖ变换电路选择以及前置电路的设计等．

| Abstract: | Although the digital thermometer has become the most common instrument in processautomation, its usage is limited in certain industrial fields, especially that of precisionmeasurement. The author has developed a variety of less than 0.1 degree centigrade, inmany cases less than 0.03 degree centigrade, the choice of thermometric sensors, thenonlinear correction of resistance, R-V conversion, and the design of prePosed circuits. |
