Ezimweni zanamuhla zezimboni nezohwebo, ikhono lokulinganisa nokuqapha amazinga oketshezi ngokunembile libalulekile ukuze kuqinisekiswe ukuphepha, ukusebenza kahle, nokusebenza okufanele kwesistimu. Obunye bobuchwepheshe obuthembeke kakhulu benzwa yeleveli inzwa yeleveli ye-capacitive, futhi ikakhulukazi, inzwa yeleveli ye-TN. Lezi zinzwa zisetshenziswa kabanzi ezimbonini ezahlukahlukene ezifana nokwelashwa kwamanzi, ukucubungula amakhemikhali, nokukhiqizwa kokudla, phakathi kokunye.
Kwa-Bluefin Sensor Technologies Limited, sisebenza ngokukhethekile ekunikezeni izixazululo zezinzwa ezisezingeni eliphezulu ezisiza ukuthuthukisa izinqubo zakho nokuvimbela isikhathi sokuphumula esibizayo. Ukuqonda ukuthi izinzwa zeleveli ye-TN zisebenza kanjani nokuthi kungani zisebenza kahle ezinhlelweni eziningi kangaka kungathuthukisa kakhulu inqubo yokuthatha izinqumo lapho ukhetha inzwa efanele yezidingo zakho.
Kulo mhlahlandlela obanzi, sizongena sijule endleleni izinzwa zeleveli ye-TN ezisebenza ngayo, ukusetshenziswa kwazo, izinzuzo, kanye nokucatshangelwa okuhlukile okufanele kucatshangelwe lapho uzisebenzisa ekusebenzeni kwakho.
Yiziphi Izinzwa Zezinga Le-TN?
A Inzwa yeleveli ye-TN iwuhlobo lwenzwa yeleveli ye-capacitive esebenzisa isimiso sokukwazi ukukala izinga loketshezi noma okuqinile esitsheni noma ithangi. Izinzwa ze-Capacitive zisebenza ngokulinganisa ushintsho kumandla njengoba inzwa ithintana nokokusebenza. Lolu shintsho lubonisa izinga lento, okuyenza ibe yindlela ethembekile yokuqapha nokulawula i-inventory, amazinga oketshezi, nokucubungula impahla.
Lezi zinzwa zivame ukusetshenziselwa ukulinganisa izinga elingahlaseli, okusho ukuthi zingakwazi ukubona ileveli ngaphandle kokuthinta ngokoqobo uketshezi noma into. Lokhu kubenza bafaneleke kakhulu ezindaweni lapho ukuthintana nento kungenzeki noma kungafuneki. Inzwa ye-TN ivamise ukusetshenziselwa izinhlelo zokusebenza lapho ukunemba, ukuqina, nokuthembeka kuwukhiye.
Zisebenza kanjani Izinzwa Zeleveli Ye-Capacitive
Izinzwa zeleveli ye-Capacitive, okuhlanganisa nezinzwa zeleveli ye-TN, zikala ukungaguquguquki kwe-dielectric kokubalulekile ngaphakathi kwethangi noma isitsha. I-dielectric constant isho ikhono lempahla lokugcina amandla kagesi lapho evezwe endaweni kagesi. Njengoba izinga lezinto ezibonakalayo lishintsha, ukungaguquguquki kwe-dielectric yesikhala phakathi kwenzwa nezinto ezibonakalayo kuyashintsha, okube sekutholwa inzwa.
Umgomo Oyisisekelo Wokusebenza Wezinzwa Zezinga le-TN:
1. I-Capacitance Measurement: Inzwa iqukethe amapuleti amabili e-conductive (ama-electrodes) ahlukaniswe yi-insulating material. Njengoba izinga lempahla (eliwuketshezi noma eliqinile) likhuphuka noma lehla, i-dielectric constant phakathi kwamapuleti iyashintsha. Lolu shintsho lwamandla lulingana ngokuqondile nezinga lezinto ezibonakalayo.
2. Ukucutshungulwa Kwesiginali: I-elekthronikhi yangaphakathi yenzwa iguqula uguquko lwamandla lube isignali ehambisanayo yokuphumayo (efana no-4-20 mA noma okukhiphayo kwedijithali). Lesi siginali yokuphumayo singabe sesihunyushwa isistimu yokulawula noma idivayisi yokuqapha ukuze kutholwe ileveli yento enembile.
3. Ukulinganisa: Izinzwa zeleveli ye-TN ziyalinganiswa ukuze kuqinisekiswe ukuthi zinikeza izilinganiso ezinembile ngokuhamba kwesikhathi. Ukulinganisa kuhlanganisa ukusetha inzwa ukuthi ibone ukungaguquguquki kwe-dielectric okufunayo kanye namaleveli ahambisanayo okukhiphayo.
Izinzuzo ze-TN Level Sensors
KwaBluefin Sensor Technologies Limited, sisebenze nezimboni ezihlukahlukene ezizuze kakhulu ekusebenziseni izinzwa zezinga le-TN.
