TURCK displacement sensor common fault analysis introduction

Analysis of common faults of German TURCK displacement sensor
The principle of linear displacement sensor is the same as that of sliding varistor. It is used as a voltage divider. It uses the relative output voltage to show the actual orientation of the measured azimuth. There are several requests for the operation of this device:
1. If the electronic ruler has been in use for a long time, and the seal is now aging, mixed with many impurities, the oil and water mixture will seriously affect the touch resistance of the brush, so that the displayed number will continue to jump. This time can be said that the electronic ruler of the Turck turck linear displacement sensor is now damaged and the demand is replaced.
2. If the capacity of the power supply is small, many situations will occur. Therefore, the power supply must have sufficient capacity. Then, if the capacity is insufficient, the following situation will be formed: the movement of the glue will change the display of the clamped electronic ruler, and there will be fluctuations. Perhaps the movement of the mold will cause the appearance of the electronic ruler of the glue to be shaken, resulting in a large error in the measurement results. If the driving power of the solenoid valve is together with the power supply of the Turck turck linear displacement sensor, it is easier to present the above situation. When the situation is serious, use the voltage range of the multimeter until the voltage fluctuation can be measured. If the situation is not due to high frequency disturbance, static disturbance or neutralization is not good enough, then it may be that the power of the power supply is too small.
3. Both frequency-frequency disturbance and static disturbance may cause the figure of the electronic scale of the Turck turck linear displacement sensor to jump. The signal line of the electronic ruler is separated from the strong electric line of the device. It is necessary for the electronic ruler to use the grounding bracket forcibly, and together the outer casing of the electronic ruler is in good contact with the ground. Signal wire Use a shielded wire and a section of the electrical box should be grounded to the shielded wire.
If there is a high frequency disturbance, the voltage measurement using the multimeter will appear normal, but the number will be beaten constantly; when the static interference is present, the situation will be the same as the high frequency interference. To verify that it is statically disturbed, you can use a length of power cord to short the cap screws of the electronic ruler to some metal on the machine.

4. If the electronic ruler of the TURCK TURCK linear displacement sensor is in the process of the operation, the data appearing at a certain point has a regular jump, or the time when the data is not displayed. In this case, it is required to check whether the insulation of the connection wire is not A phenomenon of breakage and short circuit to ground caused by regular contact with the outer casing of the machine.
5, the voltage of the power supply must be stable, the industrial voltage must meet the stability of [±O.1%], if the reference voltage is 10V, it can promise a ±0.01V shake change, if not, it will lead to The traps shake this situation. However, if the undulating fluctuations of this time show no more than the fluctuating fluctuations of the shaking voltage, then the electronic ruler is normal.
6. The linear demand of the linear Turck turck displacement sensor is excellent, but the parallelism can accept an error of ±0.5mm, and the viewpoint can accept an error of ±12°. However, if the parallelism error and the viewpoint error are both too large, this will present a situation in which the digital jitter appears. Then, when presenting such a situation, it is necessary to adjust the parallelism and the viewpoint.
7. In the process of convergence, we must pay more attention to it. The three lines of the electronic ruler cannot be connected incorrectly. The power cable and the output cable cannot be interchanged. If the above line is wrong, there will be a large linear error. It is difficult to control, the precision of the control will become very poor, and the appearance will be very simple to present the appearance of the beating.
