一、概述在海流测量中,流向是一项重要的参数,因此罗盘是任何形式的海流计所不可缺少的方向传感器,小型电位计罗盘以其体积小、重量轻、功耗低等优点而被广泛采用,尤其是短时接通式电位计罗盘,由于它只有一对机械摩擦点,接触点少,摩擦力小,准确度高,死角区最大小于2°,成本低,工作可靠,所以在海洋上使用具有独特的优点。挪威安德拉公司生产 I. Overview In the current measurement, the flow is an important parameter, so the compass is any form of flow sensor indispensable direction sensor, small potentiometer compass for its small size, light weight, low power consumption is the advantages of being Widely used, especially the short-time on-type potentiometer compass, because it has only a pair of mechanical friction point, less contact, friction, accuracy, dead zone maximum less than 2 °, low cost, reliable work, so in Use on the ocean has unique advantages.
