如何判斷線性霍爾開關(guān)是否損壞？改變磁場的大小線性霍爾開關(guān)的好壞當霍爾開關(guān)通電，輸出端與電壓表連接時，當磁鐵從遠到近接近線性霍爾開關(guān)時，線性霍爾開關(guān)的輸出電壓逐漸由小變大。這表明線性霍爾開關(guān)是好的。如果磁鐵從遠到近逐漸接近線性霍爾開關(guān)，則線性霍爾開關(guān)的輸出電壓保持不變，表明線性霍爾開關(guān)具有相同的輸出電壓。線性霍爾開關(guān)已損壞。線性霍爾開關(guān)恒流源電流的改變來判斷線性霍爾開關(guān)的質(zhì)量當線性霍爾開關(guān)恒流源的電流由零逐漸變?yōu)轭~定電流（不能超過線性霍爾開關(guān)的額定電流），線性霍爾開關(guān)的輸出電壓由小逐漸變大，說明線性霍爾開關(guān)性能良好。如果線性霍爾開關(guān)的恒流從零逐漸變?yōu)轭~定電流，則線性霍爾開關(guān)的電壓保持不變，表明線性霍爾開關(guān)已損壞。 </p><p> 8、霍爾不等位電勢（又稱霍爾偏移零點） </p> <p> 在沒有外加磁場和霍爾激勵電流為I的情況下，在輸出端空載測得的霍爾電勢差稱為不等位電勢。 </p> <p> 9、霍爾輸出電壓 </p> <p> 在外加磁場和霍爾激勵電流為I的情況下，在輸出端空載測得的霍爾電勢差稱為霍爾輸出電壓。 </p> <p> 10、霍爾電壓輸出比率 </p> <p> 霍爾不等位電勢與霍爾輸出電勢的比率。 </p> <p> 11、霍爾寄生直流電勢 </p> <p> 在外加磁場為零、霍爾元件用交流激勵時，霍爾電極輸出除了交流不等位電勢外，還有一直流電勢，稱寄生直流電勢。 </p> <p> 12、霍爾不等位電勢 </p> <p> 在沒有外加磁場和霍爾激勵電流為I的情況下，環(huán)境溫度每變化1℃時，不等位電勢的相對變化率。 </p> <p> 13、霍爾電勢溫度系數(shù) </p> <p>

霍爾元件應用霍爾效應的半導體。所謂霍爾效應，是指磁場作用于載流金屬導體、半導體中的載流子時，產(chǎn)生橫向電位差的物理現(xiàn)象。金屬的霍爾效應是1879年被美國物理學家霍爾發(fā)現(xiàn)的。當電流通過金屬箔片時，若在垂直于電流的方向施加磁場，則金屬箔片兩側(cè)面會出現(xiàn)橫向電位差。半導體中的霍爾效應比金屬箔片中更為明顯，而鐵磁金屬在居里溫度以下將呈極強的霍爾效應。利用霍爾效應可以設計制成多種傳感器。霍爾電位差UH的基本關(guān)系為：式中 RH――霍爾系數(shù)；n――單位體積內(nèi)載流子或自由電子的個數(shù)；q――電子電量；I――通過的電流；B――垂直于I的磁感應強度；d――導體的厚度。對于半導體和鐵磁金屬，霍爾系數(shù)表達式和式（2）不同。由于通電導線周圍存在磁場，其大小和導線中的電流成正比，故可以利用霍爾元件測量出磁場，就可確定導線電流的大小。利用這一原理可以設計制成霍爾電流傳感器。若把霍爾元件置于電場強度為E、磁場強度為H的電磁場中，則在該元件中將產(chǎn)生電流I，元件上同時產(chǎn)生的霍爾電位差和電場強度E成正比，如果再測出該電磁場的磁場強度，則電磁場的功率密度瞬時值P可由確定。韶關(guān)HX6659霍爾開關(guān)價格</p><p
