【摘要】 利用导磁性流体的导磁性及在重力作用下的自准水平性，以充有流体的圆盘作为微动铁芯，研制了电感差动式二自由度电子水平伙，可在一个水平面上实现３６０°范围内二自由度（正交）角度的测量，给出了传感器的输出特性以及测量电路，其结果表明，该仪器具有精度高，测量准确，快捷、方便等特点．更多还原

【Abstract】 inductance differential type two-freedom electronic levelmeter was developed bytaking advantage of the permeance of permeance nuid and automatic level by the action of gravi?ty. Two freedoms inclined angle with range of 360’ can be measured. The output characteristic ofthe sensor and measuring circuit were given. The results showed that the instrument is precise,convinient and quick in measuring.更多还原
