Linear displacement sensor is an intelligence model linear displacement measures sensor, precision of linear displacement sensor capability of forthright of tall, wiring, interference rejection is strong, apply extensively at automation system, in automation appearance and the mechanical equipment that need to have line position control, the Electromechanical that makes displacement of the lines measure changes element. The article introduces processing technique of breakdown of linear displacement sensor in detail for everybody. One, if electronic feet has been used for a long time, and sealed already ageing, at the same time be mingled with is worn a lot of impurity, and of the osculatory resistor of water mixture and brush of oily can serious effect, the number of such meeting distinguish keeps beating. This moment can say the electronic feet of linear displacement sensor had damaged, need changes. 2, the size that is like power source is very small, can appear of a lot of circumstances, so, power supply source needs to have sufficient capacity. So, the capacity is insufficient, with respect to the situation that can create as follows: The games of frit glue makes the indication of feet of electron combining a model alternates, have wave motion, the athletic meeting that perhaps closes a model makes the indication of feet of electron ejaculation glue fluctuant, cause measure result error very big. When if the drive report of electromagnetism a powerful person results from,power supply source of linear displacement sensor is together at the same time, appear more easily the circumstance of above, the voltage file that avometer uses when the case is severe can measure the concerned wave motion of voltage even. If the situation is not created well, the power that is power source likely so is too little cause. 3, the indication number of the electronic foot that frequency modulation is disturbed and static allows linear displacement sensor likely is jumpy. The strong report line of the line of electronic feet and equipment wants apart line chamfer. Electronic feet must want mandatory bracket of ground use ground connection, and the case that allows electronic foot at the same time is contacted goodly with the ground. Line needs to use screen line, and one paragraph of electric box should follow screen line ground connection. If have high frequency interference when, the tension that uses avometer normally is measured it is normal to can show, but indication number is jumpy and can ceaseless; and when occurrence static, occurrence circumstance also is as high frequency interference. When wanting to prove whether looking is static, some of a few metal weak point that can use a paragraph of power supply cord to get on the close over screw of electronic feet with the machine first is received it is OK to rise, as long as one short receive rise, static can be eliminated immediately. But if want to remove high frequency interference,use the method above very hard, electric equipment of frequency conversion part and machine hand often appear of high frequency interference, can try to use so stop electric equipment of high frequency part or the method of manipulator comes to test and verify is high frequency interference. 4, among the process that if the electronic feet of linear displacement sensor is in,works, the indication data that nods in some has regular ground to beat, when perhaps showing data, appear the phenomenon that this kind of circumstance checks jumper to be isolated from with respect to need is occurrence damaged, the right short circuit that and follow brings about. 5, the voltage of power supply must be stabilized, industrial voltage needs to accord with ± 0. The stability of 1[%] , for example, fiducial voltage is the word of 10V, OK ± of be patient of 0.
The wave motion of 01V changes, if not be, can cause indication trap to fluctuate such circumstance. But the word of the fluctuant range that if the extent of the indication wave motion of this moment is done not have,exceeds fluctuant voltage, so electronic feet is normal. 6, between connective process, must add an attention more, 3 lines of electronic feet can not receive a fault, power supply cord and output line can not exchange. If the line above receives a fault, can appear the case with linear very big error, wanting pilot word is very difficult, pilot precision also can become very poor, and show appear very easily jumpy phenomenon is waited a moment.
