1、附录附录1The quiet magnetic bar is long sharply type the displacement transducer is used in the journey and orient the control summary: This text has enumerated several kinds of commonly used transducers situations in the displacement control of the long journey of displacement, on the basis of analyzin
2、g that compares various displacement transducers principles and characteristics and limitation, have explained the long characterist Keyword: The transducer long straight line displacement of quiet magnetic bar controls PLC The object displacement examination and the control always is the industrial
3、 world is most commonly used, the most foundation localization method.The present stage product already had the huge change in the structure and the performance, the function has been more perfect, the reliability was higher, and turned towards the automation and the intellectualized direction devel
4、ops; The displacement examines the product the performance main reflection to satisfy aspects and so on accuracy, reliability, timeliness, durability and automated horizontal degree.* Magnetostatic grid position transmitter synopsisThe magnetostatic grid position transmitter, is the Wuhan sparkling
5、jade-like stone good science and technology development limited liability company develops the production in the digestion absorption world most advanced magnetic displacement sensor technology foundation the new high reliable position transmitter product, an its being published receives the metallu
6、rgy, the machinery, the petrification, the transportation, profession and so on water conservation universal favorsUses general position transmitter, liquidometer, strobe opening meter, driving traveling schedule instrumentation, cylinder stroke instrumentation which this technology produces and so
7、on in bad industry environment widespread utilization, its non-contact displacement surveys the way to be suitable for the extremely wide measuring range scope, made up the import product price high, the post-sale service has been imperfect, environment adaptiveness was bad, measuring range limitati
8、on, ordering cycle long and so on flaws, could and many kind of automatic control system connectionThis magnetostatic grid displacement surveys the technology to borrow the Vernier caliper difference scale division to measure micro the principle, depends upon the Hall line array group to move the ef
9、fect, the analysis digitization moves absolutely the code, accurate reliable, this original new technology commercialized advancement is extremely rapid.First, magnetostatic grid position transmitter principle1st, the magnetostatic grid position transmitter and the magnetostatic grid ruler two parts
10、 unifies the use by the magnetostatic grid source The magnetostatic grid source uses the aluminum alloy pressure to seal the passive neodymium iron boron magnetism grid composition magnetism grid code array; The magnetostatic grid ruler with the Inner Tibet embedded microprocessor system specially m
11、ade high strength aluminum alloy tubing seal, uses the switch Hall sensing component to compose Hall to code the array, the aluminum alloy tubing exterior use guards against the wholesale2nd, the magnetostatic grid source the spool thread does along the magnetostatic grid ruler when (relative gap la
12、titude and relative posture latitude reaches 50mm) without the contact the relative motion, by the magnetostatic grid ruler analyzes the digitized displacement information, produces directly is higher than a millimeter magnitude the displacement quantity digital signal.Excavates the embedded micropr
13、ocessor fully the resources, enhances the data renewal speed to a millisecond magnitude, in order to can adapt below 5m/S the velocity of movement displacement responseThe direct survey object displacement and the angle, the ordinary resolution threshold 1 millimeter, the highest resolution threshol
14、d may amount to 0.2 millimeter at present, Gao Cechang may amount to 2 kilometers.The mechanism has like Vernier caliper the Vernier caliper 1 millimeter scale division may distinguish 0.02 millimeter, its resolution enhanced 50 times.Magnetism grid code array spacing and Hall code the array spacing
15、 to be different, have like about Vernier caliper the difference slide guage different scale division, again passes through the algorithm which set of relapses deduce, causes the magnetostatic grid absolute encoder the resolution to be possible to amount to 0.2 millimeter3rd, the spatial magnetostat
