Giant Shanghai Automation Technology Co., Ltd sales ELGO, ELGO head, ELGO magnetic shed feet good wave of the recorded magnetic ruler called magnetic scale. Adjacent gate wave separation distance is called the magnetic scale magnetic grid wavelength, also known as magnetic grid pitch (pitch). Magnetic scale is the reference element digital magnetic grid system. Obviously, the wavelength is the length of magnetic scale unit of measure. Either the measured length corresponding to the number of available wavelengths and magnetic grid to represent. Hard magnetic alloy magnetic scale ruler body can be made to meet certain requirements. It can also be coated with a magnetic material made of a hard magnetic alloy. Made of magnetic scale of the hard magnetic alloy magnetic properties should have the following requirements: 1) good magnetic material should have a larger remanence and coercivity, that the hysteresis loop material should be more big fat. 2) good magnetic homogeneity of the uniform magnetic properties of materials as possible to ensure the recorded magnetic remanence after the magnitude equal, otherwise it will affect the accuracy of the magnetic grid. 3) The residual magnetization of the magnetic stability of the material good magnetic recording should not have after extended time and quickly with reduced performance. 4) The mechanical properties of good material should have high mechanical strength, hardness and wear resistance, easy machining and less susceptible to changes in ambient temperature and humidity. 5) a certain frequency characteristic can guarantee a certain strength requirements remanence frequency (wavelength) of the wave on the desired recording. Commonly used hard magnetic alloy is Cu-Ni-Fe alloy or Fe-Cr-Co alloy; conventional magnetic coating composition is Ni, Co, P. An important feature of the design of magnetic scale magnetic grid is the magnetic scale in contact with the head of state. Magnetic grid works magneto-electric conversion, in order to ensure a stable head output signal amplitude, taking into account the reluctance of big air, so there is a big gap between and variable magnetic scale and the magnetic head is not allowed, it is best contact type. To do this with a gate-type magnetic head at work is pressed into the tape, so instant with some uneven surface, the magnetic head and the magnetic tape can be a good contact. Between linear magnetic grid of magnetic scale and the head gap of about 0.01mm, since assembly and adjustment is not possible to achieve the ideal state, so in fact quasi-linear magnetic grid is also in contact working condition. Another important feature of the magnetic grid is magnetic scale in a certain tension. Advantages magnetic scale of non-contact measurement, without backlash problem, easy installation and maintenance, high precision, long stroke length from 0.1 to 100 meters unlimited access, high contamination resistance, without losing accuracy in environment is very harsh environment, water, oil, iron work, easy to install, the installation tolerances big cheap, yet magnetism decade.
