Abstract
Aiming at the issue of temperature drift in measurement, this paper discusses its practical solutions from the following aspects: the selection of temperature sensors, selection of measuring program, practical measuring circuit and filtering algorithm, and proposes a scheme of the signal amplification and conditioning circuit of two AD623 and AD conversion circuit, including the applicational interface circuit with microcontroller. The practical application shows that the scheme meets the design requirements: of ±0.1 ℃ resolution and ± 0.2 ℃ accuracy.关键词
