Ndi Mitundu Yanji Yosiyanasiyana ya Sensor Level Liquid?

Mitundu yosiyanasiyana ya masensa amadzimadzi ndi awa:

Mtundu wa Optical

Capacitive

Conductivity

Diaphragm

Mtundu wa mpira woyandama

1. Optical madzi mlingo sensa

Zosintha zowoneka bwino ndizolimba. Amagwiritsa ntchito ma infrared leds ndi phototransistors, omwe amalumikizidwa bwino pamene sensa ili mumlengalenga. Pamene mapeto akumva amizidwa mumadzimadzi, kuwala kwa infuraredi kumatuluka, zomwe zimapangitsa kuti kusinthako kusinthe. Masensa amenewa amatha kudziwa kupezeka kapena kusapezeka kwa pafupifupi madzi aliwonse. Sakhudzidwa ndi kuwala kozungulira, sakhudzidwa ndi thovu mumlengalenga, ndipo samakhudzidwa ndi tinthu ting'onoting'ono tamadzimadzi. Izi zimapangitsa kuti zikhale zothandiza pazochitika zomwe kusintha kwa boma kumafunika kulembedwa mofulumira komanso modalirika, ndipo kumatha kugwira ntchito modalirika kwa nthawi yaitali popanda kukonza.

Kuipa kwa optical level sensor ndikuti imatha kudziwa ngati madzi alipo. Ngati milingo yosinthika ikufunika, (25%, 50%, 100%, etc.) iliyonse imafunikira sensor yowonjezera.

2. Capacitive madzi mlingo sensa

Kusintha kwa capacitive kumagwiritsa ntchito ma conductor awiri (omwe nthawi zambiri amapangidwa ndi chitsulo) mozungulira ndi mtunda waufupi pakati pawo. Kondakitala akamizidwa mumadzimadzi, amamaliza kuzungulira.

Ubwino wa capacitive level switch ndikuti ungagwiritsidwe ntchito kudziwa kukwera kapena kugwa kwamadzi mumtsuko. Mwa kupanga kondakitala msinkhu wofanana ndi chidebe, capacitance pakati pa oyendetsa akhoza kuyesedwa. Palibe capacitance kutanthauza palibe madzi. Capacitor wathunthu amatanthauza chidebe chodzaza. Muyenera kulemba miyeso "yopanda" ndi "yodzaza" ndikuyesa mita ndi 0% ndi 100% kuti muwonetse mulingo.

Ngakhale ma sensor a capacitive level ali ndi mwayi wosakhala ndi magawo osuntha, chimodzi mwazovuta zake ndikuti dzimbiri la kondakitala limasintha mphamvu ya kondakitala ndipo kumafuna kuyeretsa kapena kukonzanso. Amakhudzidwanso kwambiri ndi mtundu wamadzimadzi omwe amagwiritsidwa ntchito.

3. Conductive madzi mlingo sensa

Kusintha kwa conductive level ndi sensor yokhala ndi kukhudzana kwamagetsi pamlingo wina. Gwiritsani ntchito ma kondakitala awiri kapena kupitilira apo okhala ndi malekezero owonekera mupaipi yomwe imatsikira mumadzi. Kutalika kumanyamula magetsi otsika, pamene woyendetsa wamfupi amagwiritsidwa ntchito kumaliza dera pamene mlingo ukukwera.

Monga ma switches a capacitive level, masiwichi a conductive level amadalira ma conductivity amadzimadzi. Choncho, ndi oyenera kuyeza mitundu ina ya zakumwa. Kuonjezera apo, mapeto a sensa awa amafunika kutsukidwa nthawi zonse kuti achepetse litsiro.

4. Diaphragm level sensor

Kusintha kwa diaphragm kapena pneumatic level kumadalira kuthamanga kwa mpweya kukankhira diaphragm, yomwe imagwira ntchito ndi micro switch m'thupi la chipangizocho. Pamene mlingo ukukwera, kupanikizika kwamkati mu chubu chodziwikiratu kumakwera mpaka microswitch kapena pressure sensor imatsegulidwa. Pamene mulingo wamadzimadzi ukutsika, kuthamanga kwa mpweya kumatsikanso ndipo chosinthira chimachotsedwa.

Ubwino wa masinthidwe otengera diaphragm ndikuti palibe chifukwa chopangira magetsi mu thanki, itha kugwiritsidwa ntchito ndi mitundu yambiri yamadzimadzi, ndipo popeza chosinthira sichimakumana ndi madzi. Komabe, popeza ndi makina amakina, pamafunika kukonza pakapita nthawi.

5. Sensa yamadzimadzi yoyandama

Chosinthira choyandama ndiye sensor yoyambira. Ndi zipangizo zamakina. Paphata pa Chichewa choyandama chomangika pamkono. Pamene choyandamacho chikukwera ndi kugwera mumadzimadzi, mkono umakankhidwira mmwamba ndi pansi. Mkono ukhoza kulumikizidwa ndi maginito kapena makina osinthira kuti adziwe / kuzimitsa, kapena akhoza kugwirizanitsidwa ndi mlingo wa mlingo womwe umatuluka kuchokera kudzaza mpaka wopanda kanthu pamene mlingo ukutsika.

Chophimba chozungulira chozungulira mu thanki ya chimbudzi ndi sensor yodziwika bwino yoyandama. Mapampu a sump amagwiritsanso ntchito masiwichi oyandama ngati njira yochepetsera ndalama kuyeza kuchuluka kwa madzi m'ma sump apansi.

Ma switch oyandama amatha kuyeza mtundu uliwonse wamadzimadzi ndipo amatha kupangidwa kuti azigwira ntchito popanda magetsi. Kuipa kwa masiwichi oyandama ndikuti ndi akulu kuposa masiwichi amtundu wina, ndipo chifukwa ndi makina, amafunikira kutumikiridwa pafupipafupi kuposa masiwichi ena.
