The magnetic grid is also known as the magnetic feet, is a detection device using the electromagnetic method to record the number of magnetic waves. The condition of the use environment is low, and the anti-interference ability of the surrounding magnetic field is strong, in the place where the oil and dust are used. Good stability.

A Tongmagnetic meter + reading head

The working principle of the magnetic gate is magnetoelectric conversion, in order to ensure that the magnetic head has a stable output signal, considering that the magnetic resistance of the air is large, there is no large and variable gap between the magnetic grid and the magnetic head, preferably Contact. For this purpose, the magnetic grid is pressed on the tape, so that there is some unlatten surface, and the magnetic head is also good contact. There is a gap between the magnetic gate and the magnetic edge of the line type magnetic gate and the magnetic head of the magnetic head. Due to the ideal state of assembly and adjustment, the actual line type magnet gate is also in the quasi-contact operation.

The magnetic gate is also a sensor for detecting displacement, and its price is lower than the grating, which has a simple production, easy to install, adjustment, measuring range (0.001mm- Ten meters), anti-interference ability. At present, measurement resolution is 1-10um, and the system accuracy is ± 0.001mm / m. And the price of the magnetic scale is also more close.

The magnetic meter is a displacement sensor that is measured by the magnetic action of the magnet and the magnetic head, which is low and easy to install and use. When desired, the original magnetic signal (magnetic gate) can be erased and re-recording. You can also be installed on the machine to record magnetic signals to eliminate geometric errors in installation errors and machine tool itself.

An important feature of the magnetic gate is two: one is the working state of the magnetic gate and the head in the contact. The working principle of the magnetist is magnetoelectric conversion, taking into account the magnetic resistance of the air, in order to ensure that the magnetic head has a stable output signal amplitude, there is no large and variable gap between the magnetic grid and the magnetic head, preferably Contact. For this purpose, the magnetic gate is pressed onto the tape, so that even if it is substantial, it is not flat, the magnetic head and the tape can also be good contact. There is a gap between the magnetic gate and the magnetic edge of the line type magnetic gate and the magnetic head of the magnetic head. Due to the ideal state of assembly and adjustment, the actual line type magnet gate is also in the quasi-contact operation.

Astro Ma magnetic grid reads a small product, the product is small and exquisite, convenient for small space installation, using a full metal shell design, all imported soft and wear-resistant cable, anti-interference hardware and software circuit design, reliable performance double improvement

Treatment of complicated adverse work environments such as oil, liquid, dust, vibration

.

When using the magnetic gate, you should pay attention to the following:

1. Power supply voltage is stable (if the display fluctuation amplitude at this time does not exceed the fluctuation amplitude of the fluctuation voltage, the electronic ruler belongs to normal).

2. Power supply has sufficient capacity. If the power supply is too small, it is easy to happen: the molding might leads to the display of the hoe, or the melt sport will cause the display fluctuation of the composite electronic ruler. In particular, the solenoid valve drives the power supply from the electronic scale power supply, which is easy to appear, and can measure the fluctuation of the voltage with the voltage frame of the multimeter when severe. If the problem is eliminated, high frequency interference, the problem cannot be solved in the case of neutrality, and it can be suspected to be a power supply.

3. Electrostatic interference and FM interference can easily display digital beats.

4. Installation is good (if you have digital beating, you must adjust the angle and flatness of the angle).

5. For a magnetic meter having a long time (there is a lot of impurities, there is a mixture of oil water, which can affect the contact resistance of the brush, resulting in displaying digital beating, can initially infer the early damage of the magnetic grid itself).

6. There is no data, or regular display data beating in a certain point, there is such a situation, and it is timely check whether the connection line insulation is damaged and has a regular contact with the machine’s metal casing.
