1. If the electronic ruler has been used for a long time, and the seal is now aging, it is mixed with a lot of impurities, and the water mixture and oil will seriously affect the contact resistance of the brush, which will make the displayed numbers constantly beat. At this time, it can be said that the electronic ruler of the linear displacement sensor is now damaged and needs to be replaced.
Second, if the capacity of the power supply is very small, there will be a lot of situations, so the power supply demand has sufficient capacity. Then, if the capacity is insufficient, the following situation will be formed: the movement of the melt will change the appearance of the clamping electronic ruler and shake, or the movement of the clamping will shake the appearance of the injection electronic ruler, and the measurement results will be greatly wrong. If the driving power supply of the solenoid valve is together with the power supply of the linear displacement sensor, it is easier to present the above situation, and the voltage level of the multimeter can even measure the relevant fluctuation of the voltage when the situation is serious. If the condition is not due to high-frequency disturbance, electrostatic disturbance, or neutralization is not good enough, then it is possible that the power of the power supply is too small.
3. Frequency modulation disturbance and electrostatic disturbance may make the display digital jump of the electronic ruler of the linear displacement sensor. The signal line of the electronic ruler should be separated from the strong current line of the equipment. It is necessary to use the grounding bracket mandatorily for the electronic ruler, and make good contact between the shell of the electronic ruler and the ground. The signal line needs to use a shielded wire, and a section of the electrical box should be grounded with the shielded wire. If there is a high-frequency disturbance, the voltage measurement of the general multimeter will appear normal, but the display number will beat continuously; In the case of electrostatic disturbance, the situation is the same as that of high-frequency disturbance. To prove whether it is static disturbance, you can first use a section of power cord to connect the cover screw of the electronic ruler with some metal on the machine. However, if you want to eliminate the high-frequency disturbance, it is difficult to use the above method, the frequency converter saver and the robot often present high-frequency disturbance, so you can try to use the method of aborting the high-frequency economizer or manipulator to verify whether it is high-frequency disturbance.
Fourth, if the electronic ruler of the linear displacement sensor is next to the process of work, the display data at a certain point beats regularly, or there is no display data.
Fifth, the voltage of the power supply must be stable, the voltage demand of the industry meets the stability of ±0.1[%], for example, if the reference voltage is 10V, it can promise to have a fluctuation change of ±0.01V, if not, it will cause the situation of the apparent scam shaking. However, if the fluctuation of the appearance at this time does not exceed the fluctuation of the fluctuation of the fluctuating voltage, then the electronic ruler is normal.
6. The neutralization requirements of the linear displacement sensor of the device are very good, but the parallelism can be promised to have an error of ±0.5mm, and the angle can be promised to have an error of ±12°. However, if the parallelism error and angle error are too large, the number jumps will appear. When this happens, it is necessary to adjust the parallelism and angle.
Seventh, in the process of connection, we must pay more attention to the three lines of the electronic ruler can not be wrong.
