Inzwa ezingeni amanzi: ngezigaba, umsebenzi, incazelo zedivayisi

Supply of ezingeni amanzi isetshenziswa ukulawula ezingeni ketshezi amathangi ezahlukene. Lezi amadivayisi asetshenziselwa ukulawula uzamcolo, ukulawula amanzi lokukhulisa neziyingi; ekhaya, zisetshenziswe imishini yokuwasha, enhlanganweni amasistimu kwamanzi nokuthuthwa Ukushisa izinhlelo, kanye nokunye. d.

Ukwahlukanisa kanye nencazelo

Lezi amadivayisi kuye indlela yokukala kungenziwa ihlukaniswe contact kanye non-contact. Inzwa ezingeni amanzi yohlobo yokuqala etholakala ngqo odongeni ithangi, ke sekuqalile oxhumana okwamanje ekufezeni ezingeni ketshezi lapho ibekwe. Ngaphezu kwalokho, amanzi izinga nesilinganiso kungaba kwenziwe nge izindlela ezilandelayo :. Capacitive, kazibuthe, optical, ultrasonic, njll I inzwa optical ezingeni amanzi uye akukho izingxenye ezinyakazayo, it is ogibele odongeni ithangi futhi kwabangela phezu ukufinyelela ezingeni kusengaphambili. optical imisebe uphazamisa kubangela ushintsho isignali ku okukhiphayo zedivayisi.

Inzwa izinga lamanzi (iflothi), yidivayisi ngokunemba jikelele eziningi ezahlukahlukene kwezicelo ezahlukene ezidinga olunembile kakhulu uketshezi ukugeleza izilinganiso. amadivaysi ezinjalo esalisekela futhi multi-level, kanye lwento (analog).

Indawo engalapho ezingeni amanzi inzwa ongasebenza nge uketshezi ezahlukene, ukudla okuqinile futhi izinto nge ntshashintshe of ubuthi futhi viscosity. Amadivayisi anjalo zihlukaniswe amadivayisi capacitive kanye ultrasonic.

amadivaysi Imininingwane (Lizinga) kukhona ukuxhumana ketshezi, basuke kulinganiswa. Zingase bacwiliswa emanzini (ezifana radar noma hydrostatic) noma linamathele odongeni tank at ukuphakama predetermined (ekuphambukeni optical amadivayisi vibratory). Ziyakwazi optical, piezoelectric ekuphambukeni, radar noma radar, hydrostatic kanye fibre optic.

Indlela yokwenza inzwa ezingeni amanzi ethangini?

Uma unganelisekile imikhiqizo edayiswa ezitolo, zama ukwenza leli thuluzi bebodwa, ikakhulukazi ngoba ulula. Inzwa, ehlongoza ukuba ukunakwa kwakho, isetshenziswa ukulawula ezingeni ketshezi ezikhundleni ezehlukene. Ngu kule divayisi isignali senziwe noma ukuvala kwe-futha amanzi noma mkhosi. Idivayisi kuyinto DC amplifier elula, kwakhiwa okuyinto phezu transistors ezimbili. Kusilungisi ikuvumela ukufaka ukuzwela ezidingekayo zedivayisi. Transistors avikelekile Semiconductor diode. I-apharathasi inikeza lwalubonisa LED olulodwa ngokufanele kwi ngalendoda we Transistor kuqala. Ukuze bahlangane sidinga resistors (220 kOhm, 10 kOhm -. Amayunithi 3, 1.2 ohms), Omunye capacitor (470 UF / 50 V), transistors ezimbili (VS547), diode (1N4001) nokukodwa LED. isikimu okunjalo lusekelwa ngamandla voltage ngqo ka 6-15V futhi sisebenzisa i kagesi of 75 ma.

Inzwa ingasetshenziswa njengendlela ipuleti fiberglass ucwecwe (10 x 50 mm). Bona kufanele isethelwe ku 3 mm owangaphakathi ucwecwe.

isiphetho

Efingqa, Omet, ukuthi zinsizakuphila ziwusizo kakhulu, ikakhulukazi engxenyeni ezimele. Uzenzela: lokhu inzwa ingafakwa ethangini ukuze eshaweni noma ubhavu, lapho ngokunisela engadini kwenhlangano, kanye isitoreji izinhlelo amanzi ekhaya lakho.
