Ndeapi Marudzi Akasiyana eLiquid Level Sensors?

Mhando dzakasiyana dzemvura level sensors dzinosanganisira:

Optical type

Capacitive

Conductivity

Diaphragm

Float bhora mhando

1. Optical liquid level sensor

Optical level switches yakasimba.Ivo vanoshandisa infrared leds uye phototransistors, ayo akabatanidzwa optically kana sensor iri mumhepo.Kana magumo ekunzwa akanyudzwa mumvura, mwenje we infrared unopukunyuka, zvichiita kuti kubuda kuchinje mamiriro.Aya masensa anogona kuona kuvepo kana kusavapo kweanenge chero mvura.Havana hanya nechiedza che ambient, haabatwi nemapupu ari mumhepo, uye haabatwe nemabhuru madiki muzvinwiwa.Izvi zvinoita kuti zvive zvakakosha mumamiriro ezvinhu apo shanduko dzehurumende dzinoda kurekodhwa nekukurumidza uye nekuvimbika, uye dzinogona kushanda dzakavimbika kwenguva yakareba pasina kuchengetedza.

Iko kusakosha kweiyo optical level sensor ndeyekuti inogona chete kuona kana mvura iripo.Kana mazinga akasiyana-siyana achidiwa, (25%, 50%, 100%, nezvimwewo) imwe neimwe inoda imwe sensor.

2. Capacitive fluid level sensor

Capacitive level switches inoshandisa ma conductor maviri (anowanzo gadzirwa nesimbi) mudunhu rine chinhambwe chipfupi pakati pavo.Kana conductor akanyudzwa mumvura, inopedza dunhu.

Chakanakira che capacitive level switch ndechekuti inogona kushandiswa kuona kukwira kana kudonha kwemvura mumudziyo.Nekuita kuti conductor aenzane kureba semudziyo, iyo capacitance pakati pemakonduri inogona kuyerwa.Hapana capacitance zvinoreva kuti hapana mvura.A full capacitor zvinoreva mudziyo uzere.Iwe unofanirwa kurekodha zviyero "zvisina chinhu" uye "zvizere" wobva wagadzirisa mita ne0% uye 100% kuratidza mwero.

Kunyange zvazvo capacitive level sensors ine mukana wekusava nezvikamu zvinofamba, chimwe chezvisina kunaka ndechekuti kuora kwe conductor kunoshandura capacitance ye conductor uye inoda kuchenesa kana kudzokorora.Ivo zvakare vanonyanya kufunga nezvemhando yemvura inoshandiswa.

3. Conductive fluid level sensor

A conductive level switch is sensor ine magetsi ekubata pane imwe nhanho.Shandisa ma conductor maviri kana anopfuura ane inductive ends mupombi inodzika mumvura.Iyo yakareba inotakura yakaderera voltage, nepo mupfupi conductor inoshandiswa kupedzisa dunhu kana mwero wakwira.

Senge capacitive level switch, conductive level switch inotsamira pane conductivity yemvura.Naizvozvo, ivo vanokodzera chete kuyera mamwe marudzi ezvinwiwa.Pamusoro pezvo, idzi sensor sensing magumo dzinoda kucheneswa nguva nenguva kuderedza tsvina.

4. Diaphragm level sensor

Iyo diaphragm kana pneumatic level switch inotsamira pakumanikidzwa kwemhepo kusundira diaphragm, iyo inobata ne micro switch mumuviri wechishandiso.Sezvo nhanho ichikwira, kumanikidzwa kwemukati muchubhu yekuona inokwira kusvikira microswitch kana kuti pressure sensor inoshandiswa.Kana iyo nhanho yemvura inodonha, mhepo yekumanikidza inodonhawo uye switch inobviswa.

Kubatsira kweiyo diaphragm-yakavakirwa level switch ndeyekuti hapana chikonzero chekupihwa kwemagetsi mutangi, inogona kushandiswa nemhando dzakawanda dzezvinwiwa, uye sezvo switch isingasangani neiyo mvura.Nekudaro, sezvo chiri chigadziriso chemuchina, chinoda kuchengetedzwa nekufamba kwenguva.

5. Float liquid level sensor

Iyo float switch ndiyo yekutanga level sensor.Iwo michina michina.Gomo rinoyangarara rinosungirirwa paruoko.Sezvo chinoyangarara ichikwira ichidonha mumvura, ruoko rwunosundirwa kumusoro nekudzika.Ruoko runogona kubatanidzwa kune magineti kana mechanical switch kuti uone pa/kudzima, kana kuti inogona kubatanidzwa kune level geji inosimuka kubva pakazara kuenda isina kana nhanho inodonha.

Iyo spherical float switch mutangi rechimbuzi ndeye yakajairika yekuyangarara level sensor.Mapombi eSump anoshandisawo maswichi anoyangarara senzira ine hupfumi yekuyera mazinga emvura mumakamuri epasi.

Float switches inogona kuyera chero mhando yemvura uye inogona kugadzirwa kuti ishande isina magetsi.Izvo zvisingabatsiri zvema float switches ndezvekuti akakura kupfuura mamwe marudzi ekuchinja, uye nekuti ari emakanika, anofanirwa kushandirwa kakawanda kupfuura mamwe mazinga ekuchinja.
