如圖3a所示，線圈112由pcb322的頂側(cè)上的跡線302和pcb322的底側(cè)上的跡線304形成。跡線302和跡線304通過穿過pcb322而形成的通孔306電接合。如圖3a所示，通孔306、頂側(cè)跡線302和底側(cè)跡線304被布置為允許形成余弦定向線圈112。例如，部分310和部分312允許線圈112交叉以形成環(huán)路114、環(huán)路116和環(huán)路118，同時在相交處將跡線分離。如進一步示出的，部分314、部分316、部分318和部分320允許余弦定向線圈112覆蓋在pcb上。然而，通孔306和pcb322的相對的兩側(cè)上的跡線302和跡線304的存在降低了由線圈104檢測到的信號的有效幅度。有效地，通孔306在發(fā)射線圈106和信號線圈104之間形成間隙距離，這本身對位置定位系統(tǒng)的準(zhǔn)確性有很大的影響。這還與以下相結(jié)合：由于在pcb322的頂側(cè)和底側(cè)上都形成了信號線圈104的跡線，而導(dǎo)致的金屬目標(biāo)124和pcb322上的信號線圈104之間的有效氣隙的增加。圖3b示出另一個關(guān)于對稱性的問題，其中，發(fā)射線圈106與接收線圈104是不對稱的。在圖3b所示的情況下，接收線圈104不以發(fā)射線圈106為中心，并且形成與接收線圈104和發(fā)射線圈106的連接的跡線也不對稱。圖3c示出由發(fā)射線圈106生成的磁場強度的不均勻性。如圖3c所示。山西傳感器線圈型號管道傳感器線圈，無錫東英電子有限公司。</p><div

一般用高頻蠟或其他介質(zhì)材料進行密封固定。另外，應(yīng)注意在維修中，不要隨意改變或調(diào)整原線圈的位置，以免導(dǎo)致失諧故障。（5）可調(diào)線圈的安裝應(yīng)便于調(diào)整可調(diào)線圈應(yīng)安裝在機器的易于調(diào)節(jié)的位置，以便于調(diào)整線圈的電感量達(dá)到佳的工作狀態(tài)。[2]原理電感是導(dǎo)線內(nèi)通過交流電流時，在導(dǎo)線的內(nèi)部及其周圍產(chǎn)生交變磁通，導(dǎo)線的磁通量與生產(chǎn)此磁通的電流之比。當(dāng)電感中通過直流電流時，其周圍只呈現(xiàn)固定的磁力線，不隨時間而變化；可是當(dāng)在線圈中通過交流電流時，其周圍將呈現(xiàn)出隨時間而變化的磁力線。根據(jù)法拉弟電磁感應(yīng)定律——磁生電來分析，變化的磁力線在線圈兩端會產(chǎn)生感應(yīng)電勢，此感應(yīng)電勢相當(dāng)于一個“新電源“。當(dāng)形成閉合回路時，此感應(yīng)電勢就要產(chǎn)生感應(yīng)電流。由楞次定律知道感應(yīng)電流所產(chǎn)生的磁力線總量要力圖阻止原來磁力線的變化的。由于原來磁力線變化來源于外加交變電源的變化，故從客觀效果看，電感線圈有阻止交流電路中電流變化的特性。電感線圈有與力學(xué)中的慣性相類似的特性，在電學(xué)上取名為“自感應(yīng)“，通常在拉開閘刀開關(guān)或接通閘刀開關(guān)的瞬間，會發(fā)生火花，這就是自感現(xiàn)象產(chǎn)生很高的感應(yīng)電勢所造成的?？傊?，當(dāng)電感線圈接到交流電源上時。</p><p> 使得用于發(fā)射線圈802的跡線中的一些跡線在pcb的一側(cè)上，而發(fā)射線圈802的其他跡線在pcb的相反側(cè)上。在一些情況下，可以優(yōu)化發(fā)射線圈以使其相對于接收線圈盡可能對稱，同時小化所需空間。圖8a示出通孔814和通孔816，它們允許將發(fā)射線圈802的跡線連接在pcb的側(cè)面之間。如圖8a和圖8b進一步所示，接收線圈包括余弦定向線圈804和正弦定向線圈806。余弦定向線圈804包括通孔818，其允許余弦定向線圈804的導(dǎo)線跡線從pcb的一側(cè)過渡到另一側(cè)。類似地，正弦定向線圈806包括通孔820，其允許在pcb的側(cè)面之間過渡正弦定向線圈806的布線。線圈布局800中包括的另一個特征是阱808、810和812的增加，這些阱進一步補償由發(fā)射線圈802生成的場的不均勻性以及由該不均勻性生成的所得偏移誤差。如線圈設(shè)計800中所示，提供阱808和阱810來調(diào)整正弦定向線圈804，并設(shè)置阱812來調(diào)整余弦定向線圈806。此外，可以提供通孔822和通孔824，使得阱808和阱812的跡線可以分別在pcb的任一側(cè)上。阱808、阱810和阱812可以例如補償由于發(fā)射線圈802生成的場中的不均勻性而引起的接收線圈804和接收線圈806中的偏差。圖9a、圖9b和圖9c示出根據(jù)本發(fā)明的一些實施例的另一種線圈設(shè)計。小型傳感器線圈，無錫東英電子有限公司。</p><div

它與電感量L和交流電頻率f的關(guān)系為XL=2πfL品質(zhì)因素品質(zhì)因素Q是表示線圈質(zhì)量的一個物理量，Q為感抗XL與其等效的電阻的比值，即：Q=XL/R。它是指電感器在某一頻率的交流電壓下工作時，所呈現(xiàn)的感抗與其等效損耗電阻之比。電感器的Q值越高，其損耗越小，效率越高。線圈的Q值與導(dǎo)線的直流電阻，骨架的介質(zhì)損耗，屏蔽罩或鐵芯引起的損耗，高頻趨膚效應(yīng)的影響等因素有關(guān)。線圈的Q值通常為幾十到幾百。電感器品質(zhì)因數(shù)的高低與線圈導(dǎo)線的直流電阻、線圈骨架的介質(zhì)損耗及鐵心、屏蔽罩等引起的損耗等有關(guān)。分布電容任何電感線圈，其匝與匝之間、層與層之間，線圈與參考地之間，線圈與磁屏蔽罩間等都存在一定的電容，這些電容稱為電感線圈的分布電容。若將這些分布電容綜合在一起，就成為一個與電感線圈并聯(lián)的等效電容C。分布電容的存在使線圈的Q值減小，穩(wěn)定性變差，因而線圈的分布電容越小越好。額定電流額定電流是指電感器有正常工作時反允許通過的大電流值。若工作電流超過額定電流，則電感器就會因發(fā)熱而使性能參數(shù)發(fā)生改變，甚至還會因過流而燒毀。允許偏差允許偏差是指電感器上標(biāo)稱的電感量與實際電感的允許誤差值。一般用于振蕩或濾波等電路中的電感器要求精度較高。換向傳感器線圈，無錫東英電子有限公司。河南新能源傳感器線圈</p><p
