上海机床厂生产的HYQ041型转台式圆度仪以往一直是配用世界上最先进的英国RTH公司传感器。该传感器为螺管式插铁型差动电感传感器,它的线圈是脱胎线圈,没有骨架,绕制非常均匀整齐,这样的结构可使铁芯的截面积相应增大,以利于提高灵敏度。根据我国现有的自粘线品种和我们现有的工艺手段绕制这样小的线圈难度较大。另外我 Shanghai Machine Tool Plant production HYQ041 rotary table round table instrument used to be equipped with the world’s most advanced British RTH company sensors. The sensor for the solenoid-type plug-type differential inductance sensor, the coil is off the coil, no skeleton, winding uniform uniform, this structure allows the core cross-sectional area corresponding increase, in order to facilitate the increase sensitivity. According to our existing self-adhesive wire varieties and our existing technology means to winding such a small coil more difficult. In addition, I
