in the thesis, a non-contact measurement technology by combining an eddy current displacement sensor with a sonic thickness sensor was put forward to measure timely real plate gap of refiner.
本文对采用电涡流传感器和超声波测厚仪组合实时非接触测量磨盘真实间隙的设计方案进行了研究和探讨。
the contact measurement is widely used to measure plate gap, but the method can't timely indicate the change of plate gap caused by plate wear.
