音频数字显示仪是一种以声频来检测物体撞击频率的仪器,以测周及测频法来测量电频率讯号,与放大整形器及检测器(话筒)组合使用,可无接触测量物体的撞击频率。是我厂在生产300MW汽轮机时,为了测取围带铆钉头的铆击数而试制的,以声频来测取指令,来控制计数门和显示,该装置成本低,效果良好。主要由:XJP-10型显示器、放大整形器、话筒等组成。技术条件:1.频率测量:输入讯号频率范围:LHz～100kHz;输入讯
Audio digital display instrument is an audio frequency to detect the impact of the collision frequency of the instrument to measure the week and frequency method to measure the electrical frequency signal, combined with the amplifier and detector (microphone) can be used without contact to measure the impact of objects frequency. Is my factory in the production of 300MW turbine, in order to measure the number of riveting rivets headband trial and audible to detect commands to control the counting gate and display, the device is low cost, the effect is good. Mainly by: XJP-10-type display, enlarge shaper, microphone and other components. Technical conditions: 1. Frequency measurement: input signal frequency range: LHz ~ 100kHz; input information
