Akagari k'imizigo ni iki?
Umuzunguruko w'ikiraro cya Wheatstone (ubu ukoreshwa mu gupima uburemere hejuru yuburyo bwubaka) watejwe imbere kandi ukundwa na Sir Charles Wheatstone mu 1843 birazwi cyane, ariko firime yoroheje ya vacuum yashyizwe muri uyu muzunguruko ushaje kandi wageragejwe Porogaramu ntabwo yunvikana neza nyamara.Inzira ntoya ya sputter yoherejwe ntabwo ari shyashya mubikorwa.Ubu buhanga bukoreshwa mubikorwa byinshi, kuva gukora microprocessor bigoye kugeza gukora rezistoriste neza kuri gage.Kuri gage zinaniza, gage ya firime yoroheje yunvikana kuri substrate ihangayikishijwe nuburyo bwo gukuraho ibibazo byinshi byugarije “gage bondage” (bizwi kandi nka gage ya fili, gage ihagaze, hamwe na silicon ya gage).
Kurinda kurenza urugero kurinda selile yimizigo bivuze iki?
Buri selile yimikorere yagenewe gutandukana munsi yumutwaro muburyo bugenzurwa.Ba injeniyeri bahindura iyi deflection kugirango barusheho kwiyumvisha ibyiyumvo mugihe bareba ko imiterere ikorera mukarere kayo "elastique".Iyo umutwaro umaze gukurwaho, imiterere yicyuma, ihindagurika hamwe nakarere kayo ka elastike, isubira muburyo bwambere.Imiterere irenze kariya karere ka elastique yitwa "kurenza urugero".Rukuruzi irenze urugero ihura na "disformasique ya plastike," aho imiterere ihinduka burundu, ntizigera isubira uko yari imeze.Iyo bimaze guhindurwa muburyo bwa plastiki, sensor ntikigitanga umurongo ugaragara ugereranije numutwaro washyizweho.Mu bihe byinshi, ni ibyangiritse kandi bidasubirwaho."Kurinda Kurenza Ibicuruzwa" ni igishushanyo mbonera kigabanya uburyo bwa sensor igabanuka munsi yumutwaro uremereye, bityo bikarinda sensor imizigo itunguranye itunguranye cyangwa ifite imbaraga zitera ubundi buryo bwo guhindura ibintu.
Nigute ushobora kumenya neza selile yimizigo?
Ukuri kwa sensor gupimwa hifashishijwe ibipimo bitandukanye.Kurugero, niba sensor yapakiwe kumurongo ntarengwa, hanyuma umutwaro ukavaho, ubushobozi bwa sensor yo gusubira mubintu bimwe bya zeru-imitwaro muri ibyo bihe byombi ni igipimo cya “hystereze”.Ibindi bipimo birimo Nonlinearity, Gusubiramo, na Creep.Buri kimwe muri ibyo bipimo ntigisanzwe kandi gifite ikosa ryacyo.Dutondekanya ibipimo byose muri datasheet.Kubisobanuro birambuye bya tekiniki yaya magambo yukuri, nyamuneka reba inkoranyamagambo yacu.
Ufite ubundi buryo bwo gusohora ibintu bya selile yumutwaro hamwe na sensor sensor usibye mV?
Nibyo, imbaho zitanga ibimenyetso byerekana ibimenyetso birahari hamwe nimbaraga zigera kuri 24 VDC kandi ubwoko butatu bwo guhitamo burahari: 4 kugeza 20 mA, 0.5 kugeza 4.5 VDC cyangwa I2C digital.Buri gihe dutanga ibicuruzwa byagurishijwe kandi bigahinduka byuzuye kuri sensor ya max.Ibisubizo byihariye birashobora gutezwa imbere kubindi bisohoka protocole.
