摘要

恒温风速计(CTA)在文献中得到了广泛的研究，通常使用NTC或PTC热敏传感器。本文采用PTC和NTC对CTA结构的灵敏度进行了比较分析。提出了一种设计CTA的方法，该方法对该配置产生最大的灵敏度。此外，还用典型传感器进行了仿真，以支持理论分析。结果表明，使用两种类型的热敏传感器的系统性能几乎相同。

Sensitivity evaluation of thermoresistive sensor constant temperature anemometers

Constant temperature anemometers (CTA) have been extensively studied in the literature, normally using NTC or PTC thermoresistive sensors. A comparative analysis of the sensitivity of CTA configurations using PTC and NTC is carried out in this work. A methodology for the design of the CTA that yields maximum sensitivity for this configuration is proposed. Furthermore, simulations using typical sensors are presented for supporting the theoretical analysis. The results show that the system performance using both types of thermoresistive sensors is practically the same.
