Electrical kuyerwa non-magetsi tsika

Electrical kuyerwa vane yakakwirira zvakarurama, kuvimbika, nyore uye cheapness. Naizvozvo, dzemagetsi mano zvave chaizvo nokuyerwa uye non-magetsi zvakawanda.

Magetsi acho kuti anoyera asiri emagetsi kwazvo unotora zvinhu zvinoriumba yakadai seiyi: Switch (transducer), kuti zvenguva mudziyo uye chakarurama.

Electrical kuyerwa nonelectrical zvakawanda - izvi chaizvoizvo kutendeuka Switch nonelectrical zvakawanda, munoti, shanduko mune mvura yakati sandara, kumhanya, tembiricha, nezvimwewo, kuchinja mune zvemagetsi variables: impedance, voltage kana ano, kuti chakayerwa chakarurama, inova nyore midziyo yemagetsi ...

Zviridzwa anoshandiswa nemagetsi kuyerwa vakakamurwa muzvikamu zviviri:

• analoginen ( "tseshki") - umo nokuyerwa mugumisiro uri rapanzvimbo mudziyo yakaratidzwa museve;

• digitaalinen - ivo analoginen-to-digitaalinen convert vatendeuki mazano Mureza kupinda digital ukoshi uye anoratidza pamusoro LCD kuratidza.

Nhasi, digitaalinen midziyo vakatsiva analoginen, ungati, zvachose, nokuti, pakutanga kwezvose,

• vari nyore kushandisa (kusiyana Analog (museve), havana chinhu chakadai kuyera rwakadini kana graded rapanzvimbo chiridzwa, zvinofanira kubata);

• ivo zvikuru analoginen rakanyatsorurama.

Zvinofanira kucherechedzwa, uye zvakanakira vakadaro mano: nemagetsi kuyerwa kubvumira kunovhenekwa vasiri magetsi tsika, kunyange rakaoma kusvika munzvimbo kana kure zvikuru.

Chimbofunga dzakananga mienzaniso miviri kuita nemagetsi kuyerwa vachishandisa mano kuyera dzisiri yemagetsi uwandu.

Wood mwando mita

Sezvo huni - hygroscopic zvinhu, aine kuchinja kwezvakatipoteredza parameters ikachinja mwando - mumwe zvivako namatanda zvinokosha saka kana kushandiswa rakapera chigadzirwa. Naizvozvo, huni yapera kuti yunifomu ezvinhu ane maonero kune ramangwana uchishandisa mamiriro.

Mumwe nzira kuti kuyera ayo mwando zviri kushandisa elektrovlagomerov. Nheyo nokushanda mwando mita ndiro kuyera mwando, yakavakirwa - magetsi ehupfumi. With mudziyo, unogona kuona rakakurumidza pasina kuparadza pehuni.

Mwando mamita muri mhando mbiri:

• Tsono - vari kwakavakirwa nokuyerwa yemagetsi kurwisa;

• capacitive (contactless) - vari inobva ukama pakati dielectric rusingaperi uye unyoro. Izvi mwando mamita vane sensors kuti murege zvinoda kutanga tsono padondo. Saka, pamusoro pemvura huni pasina vakasara pashure yakayerwa, izvo, chokwadi, avo zvinobetsera zvinhu panyaya iyi kubva hydrometers tsono.

mita nitrates

Nitrates - izvi ndizvo zvezvimwe makemikari vari kupfuura ngozi nokuti zvinogona tsime zvakakomba kutyorwa dzemuviri. Kamwe zvokudya akawanda ari mumuviri womunhu, vanogona kukonzera nitrate chepfu, siyana chisingaperi zvirwere uye zvirwere.

No nguva-pakuzadza uye anodhura basa nitrate vasabatwa iri pari pakutevedzera mudziyo unokosha diki - nitrate.

Nitratomers zvakagadzirirwa kuyera michero, miriwo uye nyama yakanaka iri nitrate kugutsikana. Hwaro kushanda ari kuyera Ion basa electrode gadziriro yakananga potentiometric nzira, migumisiro ayo vatendeuka kuva zvemagetsi mureza Proportional kuti Ion wevasungwa pamusoro NO3.

chaiyo kuonana vachiongorora (vachiongorora) inowaniswa hwekutsanangura uye kuyera nzira nitrate chigadzirwa lancing mudziyo.

Nitrate - digitaalinen chiridzwa. kukura kwayo anonyorwa imwe ruvara kuratidza.
