The instrument relies on Linear Variable Differential Transformer by exploiting the three-parameter sine fit to estimate the amplitudes of their secondary signals. Moreover, the crucial problem of interfering magnetic fields is thoroughly analyzed by means of two different models: an analytical one aimed at capturing the main physics of the phenomenon and a predictive one based on Finite Elements Method. Both models have been validated by means of simulations and experimental measurements. They provide a basis for design guidelines to an application-independent solution of the interference problem. The experimental validation of the models comprises the development of a measurement method and a measurement system for the general characterization of external magnetic fields as influence quantities for the position measurement by means of Linear Variable Differential Transformer sensors. Preliminary on-field results, gathered during Large Hadron Collider commissioning and operation at CERN, confirming the laboratory results are reported.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659334115\"\u003e\u003ch3\u003eTheory, Design, Simulations and Experimental Results within the LHC Collimation Control System\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659334115","offer_id":39485434986589,"sku":"9783659334115","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/153f1b3e-bc3a-4a95-9744-2c49ac8a7ce0.jpg?v=1772865787","url":"https:\/\/shop.autorenwelt.de\/products\/a-high-precision-position-measurement-instrument-for-collimators-von-michele-martino","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
