摘要
针对磁流体电流传感器同时受磁场和温度影响的特点,研究了基于磁流体的光学电流传感器,并搭建了测试传感器温度特性的实验系统。结果表明:在26℃~74℃范围内,由于磁流体热透镜效应引起的温度梯度和恒温水浴温度升高引起磁性纳米颗粒的布朗运动增强,所以随恒温水浴的温度升高,基于磁流体的光学电流传感器的透射率减小。
Aiming at the simultaneous influence of magnetic field and temperature on the magnetic fluid current sensor,optical current sensor based on magnetic fluid is studied and the experimental system of temperature characteristics of the sensor is built.The results show that in the range of 26℃~74℃,the thermal lens effect of magnetic fluid causes a temperature gradient,and the temperature of the constant temperature water bath increases the Brownian motion of the magnetic,therefore,the transmittance of the magnetic fluid optical current sensor decreases as the temperature of the constant temperature water bath increases.
