The Design of Used Temperature Measurement Circuit

摘要

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.
