Ndeapi marudzi emasensa emvura?
Heano marudzi manomwe emvura level sensors yereferensi yako:

1. Optical mvura level sensor
Iyo optical sensor yakasimba-nyika. Ivo vanoshandisa infrared LEDs uye phototransistors, uye kana sensor iri mumhepo, ivo vanobatanidzwa optically. Kana iyo sensor musoro yakanyudzwa mumvura, iyo infrared mwenje inopukunyuka, zvichiita kuti kubuda kuchinje. Aya masensa anogona kuona kuvepo kana kusavapo kweanenge chero mvura. Iwo haanzwi kuchiedza ambient, haabatike nefuro kana ari mumhepo, uye haana kukanganiswa nemabhuru madiki kana ari mumvura. Izvi zvinoita kuti zvive zvakakosha mumamiriro ezvinhu apo shanduko dzehurumende dzinofanira kurekodhwa nekukurumidza uye nekuvimbika, uye mumamiriro ezvinhu apo vanogona kushanda nekuvimbika kwenguva refu pasina kugadzirisa.
Zvakanakira: kusingabatanidzi kuyerwa, kurongeka kwepamusoro, uye nekukurumidza kupindura.
Zvakaipa: Usashandise pasi pezuva rakananga, mhute yemvura inozokanganisa kuyerwa kwechiyero.

2. Capacitance liquid level sensor
Capacitance level switches inoshandisa 2 conductive electrodes (kazhinji yakagadzirwa nesimbi) munharaunda, uye chinhambwe chiri pakati pavo ipfupi kwazvo. Kana iyo electrode ichinyudzwa mumvura, inopedza dunhu.
Zvakanakira: inogona kushandiswa kuona kukwira kana kudonha kwemvura mumudziyo. Nekuita iyo electrode uye mudziyo kukwirira kwakafanana, iyo capacitance pakati pemagetsi inogona kuyerwa. Hapana capacitance zvinoreva kuti hapana mvura. A full capacitance inomiririra chigadziko chakakwana. Izvo zviyero zvakayerwa zve "isina" uye "zvizere" zvinofanirwa kurekodhwa, uye ipapo 0% uye 100% calibrated metres inoshandiswa kuratidza chiyero chemvura.
Zvakaipa: Kuora kwe electrode kuchachinja capacitance ye electrode, uye inoda kucheneswa kana kudzokororwa.

3. Tuning fork level sensor
Iyo tuning fork level gauge ndeye liquid point level switch tool yakagadzirwa netuning fork musimboti. Nheyo yekushanda yekuchinja ndeyekukonzera kuzunguzika kwayo kuburikidza neresonance yepiezoelectric crystal.
Chinhu chese chine frequency yaro. Manzwiro echinhu anoenderana nehukuru, huremu, chimiro, simba… chechinhu. Muenzaniso wakajairwa weiyo resonant frequency yechinhu ndeiyi: imwechete girazi kapu mumutsara Kuzadza nemvura yehurefu hwakasiyana, unogona kuridza mimhanzi yezviridzwa nekudzvanya.

Zvakanakira: Inogona kunyatso kusakanganiswa nekuyerera, mabhubhu, mhando dzemvura, nezvimwe, uye hapana calibration inodikanwa.
Zvakaipa: Haikwanise kushandiswa mune viscous media.

4. Diaphragm liquid level sensor
Iyo diaphragm kana pneumatic level switch inotsamira pakumanikidzwa kwemhepo kusundira diaphragm, iyo inobata ne micro switch mukati memuviri mukuru wechishandiso. Sezvo huwandu hwemvura huchiwedzera, kudzvanywa kwemukati muchubhu yekuona kuchawedzera kudzamara microswitch yaitwa. Sezvo mwero wemvura unodonha, mhepo yemhepo inodonhawo, uye switch inovhura.
Zvakanakira: Iko hakuna kudikanwa kwesimba mutangi, inogona kushandiswa nemhando dzakawanda dzezvinwiwa, uye switch haizosangana nezvinwiwa.
Zvakaipa: Sezvo chiri chigadziro chemuchina, chinoda kugadziriswa nekufamba kwenguva.

5.Float mvura level sensor
Iyo float switch ndiyo yekutanga level sensor. Iwo ma mechanical equipment. Iyo hollow float yakabatana neruoko. Sezvo iyo inoyangarara ichikwira uye ichidonha mumvura, ruoko ruchasimudzwa kumusoro nekudzika. Ruoko runogona kubatanidzwa kune magineti kana mechanical switch kuti uone pa/kudzima, kana kuti inogona kubatanidzwa kune nhanho yegeji inoshanduka kubva kuzere kuenda kusisina kana mwero wemvura wadonha.

Kushandiswa kwezvinoyerera zvemapombi inzira ine hupfumi uye inoshanda yekuyera mwero wemvura mugomba rekupomba repasi.
Zvakanakira: Iyo yekuyangarara switch inogona kuyera chero mhando yemvura uye inogona kugadzirwa kuti ishande pasina chero magetsi.
Zvakashata: Iwo akakura kupfuura mamwe marudzi ekuchinja, uye nekuti ari emakanika, anofanirwa kushandiswa kakawanda kupfuura mamwe mazinga ekuchinja.

6. Ultrasonic liquid level sensor
Iyo ultrasonic level gauge idhijitari level geji inodzorwa ne microprocessor. Muchiyero, iyo ultrasonic pulse inobudiswa ne sensor (transducer). Iyo ruzha wave inoratidzwa neiyo mvura yepamusoro uye inogamuchirwa neiyo imwe sensor. Inoshandurwa kuita chiratidzo chemagetsi nekristaro yepiezoelectric. Nguva iri pakati pekutapurirana uye kugashira kweizwi wave inoshandiswa kuverenga Kuyera kwechinhambwe kusvika pamusoro pemvura.
Nheyo yekushanda yeiyo ultrasonic mvura level sensor ndeyekuti iyo ultrasonic transducer (probe) inotumira yakakwira-frequency pulse sound wave kana yasangana nepamusoro peyero yakayerwa (zvinhu), inoratidzwa, uye iyo inoratidzwa echo inogamuchirwa ne transducer uye inoshandurwa kuita chiratidzo chemagetsi. Nguva yekuparadzira yeizwi wave. Inoenzana nechinhambwe kubva pasaisai yeruzha kusvika pamusoro pechinhu. Hukama huri pakati peiyo ruzha wave kutapurirana chinhambwe S nekumhanya kweruzha C uye nguva yekufambisa inzwi T inogona kuratidzwa neformula: S=C×T/2.

Zvakanakira: kuyera kusingabatanidzi, iyo yakayerwa yepakati inenge isina muganho, uye inogona kushandiswa zvakanyanya kuyera kureba kwezvakasiyana zvinwiwa uye yakasimba zvinhu.
Zvakaipa: Kuyera kwechiyero kunokanganisa zvakanyanya nekupisa uye guruva renzvimbo yazvino.

7. Radar level gauge
Radar liquid level imvura yekuyeresa nhanho yakavakirwa pamusimboti wekufamba kwenguva. Iyo radar wave inomhanya nekumhanya kwechiedza, uye nguva yekumhanya inogona kushandurwa kuita nhanho chiratidzo nemagetsi zvikamu. Iyo probe inotumira mapuruzi akakwira-frequency anofamba nekumhanya kwechiedza munzvimbo, uye kana mapurusi asangana nepamusoro pechinhu, anoratidzwa uye anogamuchirwa neanogamuchira mumita, uye chiratidzo chedaro chinoshandurwa kuita nhanho. chiratidzo.
Zvakanakira: yakakura application renji, isina kukanganiswa nekushisa, guruva, chiutsi, nezvimwe.
Zvakaipa: Zviri nyore kugadzira kupindira echo, iyo inokanganisa kuyerwa kwechiyero.
