直线感应同步型数显表是以标准直线感应同步器作为传感元件的位移检测仪器,数字分辩率可达1μm,该表采用先进的脉冲调宽原理实现了位移量到数字的转换,它已成为高精度机床,镗床以及测量机等长度计量中很有前途的测量设备,它的使用大大提高机床操作的工作效率和产品质量。由于数显表需要精确地测量大幅度的位移量,还要实现数字跟踪显示,所以线路比较复杂,需要几千只门电路、触发器、放大器等电子元件,目前国外先进国家均已采用专用大规模集成电路。在我国,由于专用电路的开发工作起步较迟,过去的数显表只能
Linear induction synchronous digital display is a standard linear induction synchronizer as the sensing element displacement detection equipment, the digital resolution of up to 1μm, the table uses advanced pulse width modulation principle to achieve the displacement to digital conversion, it has It is a promising measuring device for length measurement of high-precision machine tools, boring machines and measuring machines. Its use greatly improves the working efficiency and product quality of machine tools. Digital display requires accurate measurement of large displacement, but also to achieve digital tracking display, so the circuit is more complex, requiring thousands of gate circuits, flip-flops, amplifiers and other electronic components, the current foreign advanced countries have adopted a large dedicated Scale integrated circuit In our country, due to the development of dedicated circuits started later, the past digital display only
