Ndeapi marudzi akasiyana eyemagetsi sensors?

Mhando dzakasiyana dzemvura dzakasarudzika sensors zvinosanganisira:

Optical mhando

Kugona

Kuita

Diaphragm

Float bhora mhando

1. Optical liquid level sensor

Optical level switches yakasimba. Ivo vanoshandisa infrared leds uye Photograttors Kana magumo ekunzwa achinyudzwa mumvura, iyo infrared mwenje inopukunyuka, ichikonzera kubuda kwekuchinja nyika. Aya ma sensors anogona kuona kuvapo kana kusavapo kweinenge chero mvura. Ivo havana hanya nechiedza chechiedza, chisina kubatwa nemabubble mumhepo, uye isina kubatwa nezvidimbu zvidiki mune zvinwiwa. Izvi zvinovaita kuti vabatsire mune mamiriro ezvinhu apo shanduko dzeNyika dzinoda kunyorwa nekukurumidza uye nekuvimbika, uye zvinogona kushanda nekuvimbika kwenguva yakareba pasina kuchengetedza.

Iko kukanganisa kweiyo Optical level sensor ndeyekuti inogona kungoziva kana mvura iripo. Kana mwero wakabatanidzwa unodikanwa, (25%, 50%, 100%, nezvimwewo) imwe neimwe inoda imwe sensor.

2. Capacitive liquid level sensor

Capacitive level switches inoshandisa mahedhi maviri (kazhinji yakagadzirwa nesimbi) mudunhu nechikamu chipfupi pakati pavo. Kana muitisi akanyudzwa mumvura, inopedzisa dunhu.

Iko mukana wechiitiko chekero switch ndeyekuti inogona kushandiswa kuona kusimuka kana kudonha kwemvura mumudziyo. Nekuita kuti conduke iyo yakakwirira yakaenzana semudziyo, kugona pakati pematiri anogona kuyerwa. Hapana kugona zvinoreva kuti hapana mvura. A yakazara capacitor zvinoreva kuti mudziyo uzere. Iwe unofanirwa kunyora iyo "isina" uye "yakazara" zviyero uye wozora mita ne 0% uye 100% kuratidza chikamu.

Kunyangwe macalative level sensors ane mukana wekushayikwa, imwe yezvakashata zvavo ndeyekuita kweContictor inochinja conductor yemucheto uye inoda kuchenesa kana kudzoreredza. Ivo zvakare vane hanya zvakanyanya kune mhando yemvura inoshandiswa.

3. Kuitisa mvura level sensor

Iyo yekufambisa nhanho switch ndeye sensor neyemagetsi kusangana pane yakatarwa nhanho. Shandisa maviri kana anopfuura madhiri ane mafambiro akaiswa enductive anoguma mupipi anoburukira mumvura. Iyo yakareba inotakura iyo yakaderera voltage, nepo mupfupi conductor inoshandiswa kupedzisa dunhu apo chikamu chacho chinomuka.

Kufanana necapicitute level switches, kuitisa nhanho switches inoenderana nekuita kweiyo mvura. Naizvozvo, ivo chete vakakodzera kuyera mamwe marudzi ezvinwiwa. Uye zvakare, iyi sensor inonzwa magumo anoda kucheneswa nguva dzose kuti uderedze tsvina.

4. Diaphragm level sensor

Iyo diaphragm kana pneumatic level switch inotsamira pakumanikidzwa kwemhepo kusundira iyo diaphragm, iyo inopinda nemuchinjiko mumuviri wemubati. Sezvo chikamu chinomuka, kumanikidzwa kwemukati mune yekuona tube inosimuka kusvikira microswitch kana kumanikidza sensor yakagadziriswa. Kana iyo svutugadzike yemvura ichidonha, kudzvinyirira kwemhepo zvakare kudonha uye switch inobviswa.

Iko mukana we diaphragm-based level switch ndeyekuti hapana chikonzero chekugovera simba mutangi, inogona kushandiswa nemhando dzakawanda dzezvinwiwa, uye sezvo switch haina kusangana nemvura. Nekudaro, sezvo iri chishandiso chechimiro, chinoda kugadziriswa nekufamba kwenguva.

5. Float liquid level sensor

Iyo float switch ndiyo yekutanga level sensor. Iwo midziyo yemuchina. Hondo yehasha yakabatanidzwa neruoko. Sezvo iyo float inosimuka uye inowira mumvura, ruoko rwunosundirwa kumusoro uye pasi. Ruoko runokwanisa kubatana nemagineti kana mechanic switch kuti uone / kubva, kana kuti inogona kubatana neyekuyera gauge inokwira kubva kune isina chinhu sedanho remadonhwe.

Iyo spherical float switch mune chimbuzi tangi ndeye yakajairika yakajairika level sensor. Spump pumps zvakare inoshandisa inoyerera switches nenzira yehupfumi kuyera huwandu hwemvura mune yepasi pepasi.

Float Switches inogona kuyera chero rudzi rwemvura uye inogona kugadzirwa kuti ishandire pasina simba rekuwanikwa. Iko kushushikana kwehombodo switch ndeyekuti vakakura kupfuura mamwe marudzi emaswina, uye nekuti iwo ari michina, anofanirwa kushandirapo kazhinji kupfuura mamwe madiki madiki.
