Iindidi ezahlukeneyo zoluvo lwenqanaba lolwelo ziquka:

Uhlobo lwe-Optical

Unamandla

Ukuqhuba

I-diaphragm

Uhlobo lwebhola edadayo

1. Isivamvo senqanaba lolwelo lwe-Optical

Izitshixo zenqanaba le-Optical ziqinile. Basebenzisa iiledi ze-infrared kunye neefototransistors, ezidityaniswa ngokubonakalayo xa inzwa isemoyeni. Xa isiphelo soluvo sintywiliselwa kulwelo, isibane se-infrared siyabaleka, sibangele isiphumo sitshintshe imeko. Ezi zivamvo zinokubona ubukho okanye ukungabikho phantse naluphi na ulwelo. Azinaluvelwano kukukhanya okungqongileyo, azichatshazelwa ngamaqamza emoyeni, kwaye azichatshazelwa ngamaqamza amancinci kulwelo. Oku kubenza babe luncedo kwiimeko apho utshintsho lwelizwe kufuneka lurekhodwe ngokukhawuleza nangokuthembekileyo, kwaye lunokusebenza ngokuthembekileyo ixesha elide ngaphandle kokugcinwa.

Ukungalungi kwenzwa yenqanaba le-optical kukuba inokugqiba kuphela ukuba kukho ulwelo. Ukuba amanqanaba ahlukeneyo afunekayo, (25%, 50%, 100%, njl.) Ngamnye ufuna inzwa eyongezelelweyo.

2. Isivamvo senqanaba lolwelo esinamandla

Ukutshintsha kwenqanaba le-capacitive zisebenzisa abaqhubi ababini (ngokuqhelekileyo benziwe ngetsimbi) kwisiphaluka kunye nomgama omfutshane phakathi kwabo. Xa umqhubi entywiliselwa kulwelo, ugqiba isekethe.

Inzuzo yokutshintsha kwenqanaba le-capacitive kukuba ingasetyenziselwa ukumisela ukunyuka okanye ukuwa kolwelo kwisitya. Ngokwenza umqhubi ubude obufanayo nesitya, i-capacitance phakathi kwabaqhubi inokulinganiswa. Akukho capacitance kuthetha ukuba akukho lulwelo. I-capacitor epheleleyo ithetha isitya esipheleleyo. Kufuneka urekhode imilinganiselo "engenanto" kunye "egcweleyo" kwaye ulungelelanise imitha nge-0% kunye ne-100% ukubonisa inqanaba.

Nangona i-capacitive level sensors inenzuzo yokungabi namalungu ahambayo, enye yeengxaki zabo kukuba i-corrosion ye-conductor iguqula i-capacitance ye-conductor kwaye ifuna ukucocwa okanye ukulungiswa kwakhona. Zikwanovakalelo ngakumbi kuhlobo lolwelo olusetyenziswayo.

3. Isivamvo senqanaba lolwelo esiqhutywayo

Ukutshintsha kwenqanaba le-conductive yinzwa enoqhagamshelwano lombane kwinqanaba elithile. Sebenzisa izikhondaktha ezimbini okanye ngaphezulu ezigqunyiweyo ezineziphelo ze-inductive eziveziweyo kumbhobho owehla kulwelo. Ixesha elide lithwala i-voltage ephantsi, ngelixa i-conductor emfutshane isetyenziselwa ukugqiba isiphaluka xa izinga liphakama.

Njengokutshintsha kwenqanaba le-capacitive, utshintsho lwezinga lokuqhuba luxhomekeke kwi-conductivity yolwelo. Ngoko ke, zilungele kuphela ukulinganisa iintlobo ezithile zolwelo. Ukongeza, ezi ziphelo zenzwa kufuneka zicocwe rhoqo ukunciphisa ukungcola.

4. Inzwa yenqanaba le-diaphragm

I-diaphragm okanye i-pneumatic level switch ixhomekeke kuxinzelelo lomoya ukutyhala i-diaphragm, edibanisa ne-micro switch emzimbeni wesixhobo. Njengoko izinga liphakama, uxinzelelo lwangaphakathi kwi-tube yokufumanisa luphakama kuze kube yilapho i-microswitch okanye i-sensor sensor ivuliwe. Xa inqanaba le-liquid lihla, uxinzelelo lomoya luphinde lwehla kwaye utshintsho lunqanyuliwe.

Inzuzo yokutshintshwa kwinqanaba elisekelwe kwi-diaphragm kukuba akukho mfuneko yokunikezelwa kwamandla kwitanki, inokusetyenziswa kunye neentlobo ezininzi zolwelo, kwaye ekubeni ukutshintshwa akudibanisi nolwelo. Nangona kunjalo, kuba sisixhobo esisebenza ngoomatshini, siya kufuna ulondolozo ngokuhamba kwexesha.

5. Isivamvo senqanaba lolwelo oludadayo

Ukutshintsha okudadayo yinzwa yomgangatho wokuqala. Zizixhobo zoomatshini. Indawo edadayo ibotshelelwe engalweni. Njengoko i-float inyuka kwaye iwela kulwelo, ingalo ityhalwa inyuke isehla. Ingalo inokudityaniswa nokutshintsha kwamagnetic okanye komatshini ukumisela / ukuvala, okanye inokudityaniswa kwi-gauge yenqanaba ephakamayo ukusuka ngokupheleleyo ukuya engenanto njengoko inqanaba lehla.

Ukutshintsha okungqukuva okungqukuva kwitanki yendlu yangasese sisivamvo senqanaba lokudada eqhelekileyo. Iimpompo zeSump zikwasebenzisa iiswitshi ezidadayo njengendlela eyongayo yokulinganisa amanqanaba amanzi kwiisumpu ezisezantsi.

Iiswitshi ze-Float zinokulinganisa naluphi na uhlobo lolwelo kwaye zinokuyilwa ukuba zisebenze ngaphandle kombane. Ukungalungi kokutshintsha kwe-float kukuba zikhulu kunezinye iindidi zokutshintsha, kwaye ngenxa yokuba zisebenza ngoomatshini, kufuneka zinikezelwe ngenkonzo rhoqo kunolunye uhlobo lokutshintsha.
