非接触式转速测量仪

Non - Contact Measurer of Rotational Speed

本文介绍了在转速测量方面使用可编程计数器定时器总芯片及光电转换技术，在非常宽阔的转速范围内进行非接触式转速测量．这对于具有较小转矩的旋转机械，在使用接触式测速仪时所带来的转速波动，从而导致测量精度下降的难题，无疑是一种较好的解决办法．

This Paper intraduces a new method of measuring rot speed which uses programable counter/ Timer chips by photo - electronic exchange technigue and non - contact measuring of rot speed at a very wide range. For rot machinary with small rot movement measuring rot speed with contacted equipmeuts can cause speed wanes and precision drops while this non - contact measurement offers a good method for salving such difficult problems.
