Metoda instalacji r\u00f3\u017cni si\u0119 w zale\u017cno\u015bci od typu czujnika.\u00a0<\/p>

Podczas instalacji ekranowanego czujnika zbli\u017ceniowego, powierzchnia detekcji czujnika mo\u017ce by\u0107 zlicowana z powierzchni\u0105 instalacji. Jak wspomniano wcze\u015bniej, emisja pola magnetycznego jest ograniczona do g\u0142owicy cylindra, bez generowania pola magnetycznego z boku cylindra. Zalet\u0105 tej metody instalacji jest zapobieganie uszkodzeniom spowodowanym kolizj\u0105 z wykrywanym obiektem.\u00a0<\/span><\/p>

W przypadku nieekranowanych czujnik\u00f3w zbli\u017ceniowych, g\u0142owica czujnika musi by\u0107 wystawiona poza powierzchni\u0119 instalacji, poniewa\u017c jej bok mo\u017ce r\u00f3wnie\u017c emitowa\u0107 pole magnetyczne. Kluczowe jest zapewnienie pomy\u015blnego zako\u0144czenia obwodu przez pole magnetyczne w tym obszarze. Chocia\u017c ten czujnik zapewnia wi\u0119ksz\u0105 odleg\u0142o\u015b\u0107 wykrywania w por\u00f3wnaniu z ekranowanym czujnikiem zbli\u017ceniowym, istnieje ryzyko uszkodzenia z powodu obiektu. bezw\u0142adno\u015b\u0107<\/span><\/a> gdy zbli\u017ca si\u0119 do czujnika.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Dodatkowo, wa\u017cne jest, aby wzi\u0105\u0107 pod uwag\u0119, \u017ce podczas instalowania wielu czujnik\u00f3w zbli\u017ceniowych obok siebie, nale\u017cy zachowa\u0107 wystarczaj\u0105ce odst\u0119py, aby zapobiec wzajemnym zak\u0142\u00f3ceniom mi\u0119dzy czujnikami i unikn\u0105\u0107 ich uszkodzenia. zak\u0142\u00f3cenia magnetyczne<\/span><\/a>.\u00a0<\/p>
