新型光纤叶轮流速传感器的研制

本文介绍一种新型光纤叶轮流速传感器,它可测量高温,低流速气体,测量范围小2－15m/s,误差为0.1m/s,该传感器与同类顺轮流速计相比,有信号可远距离传送,精度高,体积小,结构简单等特点,适用于大磁场,高温度,空间狭窄等环境的测量。

Research on a New Type of the Fiber Impeller Sensor

This paper presents a new type of the fiber impeller sensor,which can measure the gas velocity ranged from 2m/s to 15m/s with a error of less than 0.1m/s at high temperature.Compared with other sensors of the same kinds,the sensor is more simple and smaller and the signal of which is more precise and can be transmitted to a longer distance.Therefore,the sensor is suitable to be used at a serious magnetic field,or at the high temperature,or at a limited space.
