Grating line displacement sensor (referred to as grating ruler)
A grating ruler is a measurement feedback device that operates based on the optical principles of gratings. Grating rulers are often used in closed-loop servo systems of CNC machine tools, and can be used for measuring linear displacement and angular displacement. Its measurement output is a digital pulse signal, which has the characteristics of large detection range, high detection accuracy, and fast response speed.
Grating rulers are mainly used for:
1. Displacement measurement of various measuring machinery and instruments: spring testing machine, coordinate measuring machine, projector, microscope
2Digital display systems for various types of machine tools: lathes, milling machines, grinders, boring machines, electric discharge machines, drilling machines, etc.
3Supporting use of various types of CNC machine tools: CNC milling machines, machining centers, CNC grinders, etc.
4Coordinate with grating rulerPLCUsed for displacement measurement of various automation equipment.
The working principle of grating ruler:
Grating ruler(WTBThe series is a precision grating measurement system,Suitable for precision measurement applications in compact spaces. Suitable for measuring: medical equipment,Precision modern machining equipment, CNC machining centers, machine tools, grinders, milling machines, automatic unloaders, metal plate pressing and welding machines, automated robots, production process measurement machines, linear product measurement, linear motors, linear guide positioning, etc. The grating ruler converts the displacement changes of a straight line into pulse signals. The number of pulse signals corresponds to the distance traveled, while the pulse frequency reflects the speed of motion. The grating ruler is divided into a body part, a glass grating, an aluminum alloy shell, signal lines, and adapters. The output signal of the grating ruler is a rectangular square wave,A、Bphase difference90°The two waveforms can indicate the distance and direction of movement. Zero position signal spacing50mm.
