Magnetic grating ruler and the magnetic head

Using the method of similarity and recording technology, recording in the magnetic ruler by head ( or disk ) recorded on a magnetic wave interval strictly equal a process known as magnetic recording. Magnetic tape recording has good magnetic wave is called a magnetic ruler. Magnetic grating ruler on the adjacent grid wave distance called magnetic grating wavelength, also known as the magnetic grid pitch ( pitch ).

Magnetic grating ruler is the base element magnetic grating digital readout system. Obviously, the wavelength is magnetic grating ruler length measuring unit. A measured length are available and the corresponding number of magnetic grating wavelength and said.

Made of hard alloy magnetic grating ruler body can be made to meet certain requirements. Can also be made of a magnetic material surface coated with a layer of hard magnetic alloys. Made of hard alloy magnetic railings ruler performance have the following requirements:

1 ) good magnetic materials have larger remanence and coercivity, namely loop material should have low fat.

2 ) good magnetic uniform magnetic materials can be more uniform as possible, in order to ensure the equal amplitude recorded magnetic remanence, otherwise it will affect the accuracy of the magnetic grid.

3 ) the magnetic stability of fine material recorded remanent magnetization magnetic after should not have performance along with the time extension and quickly weakened.

4 ) materials with good mechanical properties should have high mechanical strength, hardness and wear resistance, easy machining and less susceptible to outside temperature and humidity changes.

5 ) the frequency characteristics of certain can guarantee the remanent magnetization certain requirements of the book to the desired frequency ( wavelength ) of the magnetic wave.

Hard alloy is commonly used in Cu-Ni-Fe alloy and Fe-Cr-Co alloy; magnetic coating of commonly used components are Ni, Co, P.

Design of magnetic railings ruler

An important feature of the magnetic grid is the magnetic grid ruler and head in contact state. The working principle of the magnetic grid is a magnetoelectric conversion, in order to ensure the head has the output signal amplitude stability, taking into account the air reluctance, allowing no gap exists between the large and variable magnetic grating ruler and head, it is best to contact. This belt type magnetic grid work head is pressed on the tape, so instant with face some not smooth, head and the tape can also good contact. About 0.01mm of the gap between the linear magnetic magnetic grid ruler and head, because the assembly and adjustment can not reach the ideal state, so the actual line type magnetic grid also in contact state.

Another important feature of the magnetic grid is the magnetic grid ruler in a certain tension.

The magnetic grid ruler

Non-contact measurement, no backlash, convenient installation and maintenance, high precision, long stroke can be unlimited extension of 0.1-100 meters, high contamination resistance, the environment is extremely bad environment without loss of accuracy, in the water, oil, iron work, simple installation, installation allows error cheap price, ten years is not magnetic loss.
