Sensing speed sensor with vibrometer XU Yu-Bing, HE Guo-Qiang, HUANG Shu-Hong, HAN Shou-Mu, GAO Wei (Department of Thermal Engineering, Huazhong University of Science and Technology, Wuhan 430074) In order to know whether the operation of the machine is normal or not and the condition of the machine needs to be monitored, sensors should be used. Since the performance of the sensor will directly affect the function of the entire test system, it is necessary to calibrate the sensor’s main performance index ...
