摘要
介绍了以负温度系数热敏电阻为检测器件的风速传感器的测量原理,讨论了风速-电压转换的结构机理与理论推导,给出了精确的曲线以及实际线路分析,并对仪表引起的测量误差及应采取的措施进行了讨论。
The measuring principle of a wind-speed sensor （air velocity transmitter） which employs a negative temprature coefficient （NTC） thermistor as detector is described. The construction and theoretical derivation of wind speed-voltage conversion are discussed in detail. Together with high precision curves,an analysis of an actual circuit are also given.The measuring errors of the instrument and suitable measures for eliminating them are described.
