The Design of Used Temperature Measurement Circuit

Abstract:

Article Preview

Platinum resistance sensor has the characteristics of large measuring temperature range, high accuracy and stable performance. It is an ideal temperature detecting element, and it is applied widely in industry. This paper designs two kinds of temperature measurement circuits, and expounds the working elements of each kinds of project. We contrast two projects though the follow two factors: the convenience of range regulation and linearization. We choose the better projects. They are provided with applied simply, high precision and low cost.

[5] Comparatively speaking, the linearity of scheme 2 is better. The scheme 2 is the optimal scheme, If taking into account cost, and use in industrial production, you can choose the first scheme. 综合各项指标,我们可以看出,方案2、方案4、方案5受温度的影响较小,线性度也较好,其中方案5是最优方案,而对于热响应时间这一项,更取决于传感器的灵敏度,温度测量电路对其影响是很小的。如果同时考虑成本,并且用于工业生产时,可以选择第4个方案。AAA Referrence.
