Inoshanda kuBuick LaCrosse GL8 Saab Oiri Pressure Sensor 12570798

Saka ndezvipi zvikonzero zvikuru zve zero kudonha kweiyo pressure sensor?

Kutanga, kune mabhubhu kana kusvibiswa mune inonamira layer ye strain gauge.

Chechipiri, iyo strain geji pachayo haina kugadzikana.

Chechitatu, kune majoini chaiwo ekutengesa mudunhu.

Chechina, kusunungurwa kwekunetseka kwe elastomer hakuna kukwana; Uye zvakare, ine hukamawo nemagnetic field, frequency, tembiricha uye zvimwe zvinhu zvakawanda. Kukukurwa kwemagetsi kana kumwe kukukurwa kuchavepo, asi isu tinogona kudzikisira chiyero chayo kana kuigadzirisa neimwe nzira.

Zero thermal drift indekisi yakakosha inokanganisa mashandiro epressure sensor, uye yakabhadharwa zvakanyanya. Pasi rose, zvinotendwa kuti zero-point thermal drift inongoenderana nekusaenzana uye tembiricha isina mutsara yesimba-sensitive resistor, asi kutaura zvazviri, zero-point thermal drift ine chekuitawo nekureverse kuvuza kwesimba-sensitive resistor. . Panyaya iyi, polysilicon inogona kutora inorema simbi kusvibiswa mu substrate, nokudaro ichidzikisa reverse kuvuza kwesimba-sensitive resistor, kuvandudza zero-point thermal drift uye kugadzirisa kushanda kwe sensor. Ndedzipi dzimwe nzira dziripo dzekudzikisa nekugadzirisa kukukurwa kwemagetsi?

Kunze kwekukanganisa kuyerwa kwechiyero uye kuderedza kunzwisiswa kwema sensors ekumanikidza, ndezvipi zvimwe zvakakosha zvinoita zero Drift?

Iyo inonzi zero drift inoreva chiitiko chekuti kana iyo yekuisa yeamplifier ipfupi-yakatenderedzwa, pane isina kurongeka uye zvishoma nezvishoma inochinja voltage pane yekuisa. Zvikonzero zvikuru zve zero Drift isimba rekuchinja kwekushisa pane transistor paramita uye kushanduka kwemagetsi emagetsi. Mune akawanda amplifiers, iyo zero kukukurwa kweiyo yapfuura nhanho ine pesvedzero huru, uye iyo yakawanda nhanho uye amplifiers zvinhu, zvakanyanya kukomba zero kukukurwa.

Hukuru hwekukukurwa kunonyanya kuenderana nekusarudzwa kwezvinhu zvekuomesera, uye chimiro kana kuumbwa kwezvinhu zvinotaridza kugadzikana kwayo kana kupisa kunzwa. Izvo zvakakoshawo zvikuru kugadzirisa zvinhu zvakasarudzwa. Maitiro akasiyana anoburitsa akasiyana strain values, uye kiyi iri mukugadzikana kweiyo bhiriji kukosha kana shanduko yemutemo wekuita mushure mekugadzirisa kuchembera.

Kune nzira dzakawanda dzekugadzirisa kudonha, izvo zvinonyanya kutsanangurwa nemamiriro kana kugadzirwa zvinodiwa zvevagadziri. Iye zvino vagadziri vazhinji vanodzora zero kudhiraivha zvakanyanya. Kugadziriswa kwematembiricha kunogona kubhadharwa nemukati tembiricha kuramba uye kupisa zero senitivity kuramba, kuchembera uye zvichingodaro.

Kune transformer ine dunhu rekushandura, kudonha kwechikamu chedunhu kunogona kubhadharwa nekusarudza zvakanaka zvikamu uye kugadzira mamwe maseketi akakodzera.

Iyo strain material inofanirwa kunge iri zvinhu zvine high senitivity uye diki tembiricha shanduko.
