Yiziphi izinhlobo ezahlukene zezinzwa zezinga le-Liquid?

Izinhlobo ezahlukahlukene zezinzwa zezinga eliwuketshezi zifaka:

Uhlobo lwe-Optical

Capacitha

Ukubangelanisa

I-diaphragm

Ukuntanta kwebhola

1. I-Optical Liquid Sensor

Ukushintshwa kwezinga le-Optical kuqinile. Basebenzisa ama-LEDs angezinhlabelelo kanye nama-photototransistors, ahambisana ngokuhlotshaniswa lapho inzwa isemoyeni. Lapho ukuphela kokuzwa kucwiliswa kuketshezi, ukukhanya okukhanyayo kuphunyuka, kubangele ukuphuma kuguqule isimo. Lezi zinzwa zingabona ubukhona noma ukungabikho cishe kwanoma yiluphi uketshezi. Angazwelani ukukhanya okukhona, okungathinteki ngamabhamuza emoyeni, futhi kungathinteki ngamabhamu amancane ku-liquid. Lokhu kubenza balusizo ezimweni lapho kudingeka khona ukuguqulwa kombuso ngokushesha nangokwethembekile, futhi kungasebenza ngokuthembekile isikhathi eside ngaphandle kokulungiswa.

Ukungathandeki kwenzwa yezinga le-optical ukuthi kunganquma kuphela ukuthi ngabe uketshezi lukhona. Uma kudingeka amazinga aguquguqukayo, (25%, 50%, 100%, njll.) Ngayinye idinga inzwa eyengeziwe.

2. I-Capacive Liquid Sensor

Ukushintshwa kwezinga leCapacive Sebenzisa abaqhubi ababili (imvamisa eyenziwe ngensimbi) esifundeni esinebanga elifushane phakathi kwabo. Lapho umqhubi weqhudelana egxiliwe ngoketshezi, uqeda umjikelezo.

Inzuzo ye-Capacive Level switch switch ukuthi ingahle isetshenziselwe ukunquma ukukhuphuka noma ukuwa koketshezi esitsheni. Ngokwenza umqhubi wesilinganiso esifanayo nesitsha, amandla phakathi kwabaqhubi angalinganiswa. AKUKHO i-capacitance esho awukho uketshezi. I-capacitor egcwele isho isitsha esigcwele. Udinga ukurekhoda izilinganiso "ezingenalutho" ne "ezigcwele" bese ulinganisa imitha nge-0% ne-100% ukukhombisa izinga.

Yize izinzwa zezinga leCapacive zinethuba lokuthi zingenazo izingxenye ezinyakazayo, enye yezinto ezimbi ukuthi ukugcwala komqhubi kushintsha ukukhokhwa komqhubi futhi kudinga ukuhlanza noma ukuphindisela emuva. Zizwela kakhulu uhlobo loketshezi olusetshenzisiwe.

3. Isemizwa ye-Liquid Level

Ukushintshwa kwezinga le-Creattive kuyinzwa yokuxhumana kagesi ezingeni elithile. Sebenzisa abaqhubi ababili noma ngaphezulu abafakile ngemikhawulo eveziwe eveziwe ngepayipi eyehla ibe uketshezi. Uma isikhathi eside uphethe i-voltage ephansi, kanti umqhubi we-verter usetshenziselwa ukuqeda umjikelezo lapho izinga liphuma.

Njengokushintshwa kwezinga le-capacive, ukushintshwa kwezinga lokuphamba kuncike ekuvuseleni koketshezi. Ngakho-ke, zilungele kuphela ukukala izinhlobo ezithile zotshwala. Ngaphezu kwalokho, lezi zinsolo ezizwa izinzwa zidinga ukuhlanzwa njalo ukuze zinciphise ukungcola.

4. Inzwa yezinga le-diaphragm

I-diaphragm noma i-pneumatic level switch ithembele ekucindezelweni komoya ukusunduza i-diaphragm, esebenza ngokushintshana okuncane emzimbeni wedivayisi. Njengoba izinga likhuphuka, ingcindezi yangaphakathi kushubhu lokutholwa ikhuphuka kuze kube yilapho i-microswitch noma inzwa yengcindezi icushiwe. Lapho izinga le-liquid lihla, ingcindezi yomoya ibuye yehla futhi ukushintshwa kunqanyuliwe.

Inzuzo ye-Diaphragm esekwe ezingeni lokushintshana ukuthi asikho isidingo sokuhlinzekwa kwamandla ethangini, singasetshenziswa ngezinhlobo eziningi zoketshezi, futhi selokhu kushintshe kungahlali ngoketshezi. Kodwa-ke, ngoba iyithuluzi elisebenza ngomshini, lizodinga ukulungiswa ngokuhamba kwesikhathi.

I-5. Flow liquid sensor

Ukushintshwa kwe-Float yinzwa yebanga langempela. Zingamadivayisi we-mehendi. I-azell at halled inamathiselwe engalweni. Njengoba ukuntanta kukhuphuka futhi kuwele kuketshezi, ingalo icindezelwa phezulu naphansi. Ingalo ingaxhunywa ku-magrenetic noma eshintsheni imishini ukuthola ukuthi i-ON / OFF, noma ingaxhunyaniswa kwiliveli yeliveli ekhuphuka ingenalutho ingenalutho njengoba liwela.

Ukushintshwa kwe-Spherical Float ethangini lasendlini yangasese kuyinhlangano ejwayelekile kakhulu yezinga lokuntanta. Amaphampu we-SUMP nawo asebenzisa ukushintshwa okuntantayo njengendlela yezomnotho yokulinganisa amazinga wamanzi ezihlathini ezingaphansi komhlaba.

Ukushintshwa kokuntanta kungalinganisa noma yiluphi uhlobo loketshezi futhi lungaklanywa ukusebenza ngaphandle kokuhlinzekwa kwamandla. Okubi kokushintshwa kokuvutha ukuthi kukhulu kunezinye izinhlobo zokushintshana, futhi ngoba zingumshini, zidinga ukuthi zinikezwe kaningi ukwedlula ezinye izinguquko zeleveli.
