Bikurikizwa kuri Cat 330D / 336D sensor ya peteroli ya sensor EX2CP54-12

Umuvuduko wumuvuduko ufite amakosa yuzuye kandi yibeshya, kandi indishyi zamakosa ya sensor sensor nurufunguzo rwo kuyishyira mu bikorwa. Umuvuduko wumuvuduko urimo amakosa ya offset, ikosa rya sensitivite, ikosa ryumurongo hamwe nikosa rya hystereze. Uru rupapuro ruzerekana uburyo bw'aya makosa ane n'ingaruka zabyo ku bisubizo by'ibizamini, kandi icyarimwe uzane uburyo bwo guhinduranya igitutu n'ingero zikoreshwa kugirango tunonosore neza ibipimo.

Kugeza ubu, hari ubwoko bwinshi bwa sensororo ku isoko, butuma abashakashatsi bashushanya guhitamo ibyuma bikenerwa na sisitemu. Ibyo byuma bikoresha ntabwo birimo gusa ibyingenzi bihindura, ariko kandi birushijeho kuba byinshi-bihuza ibyuma bifata ibyuma bifata imiyoboro. Kubera itandukaniro, injeniyeri yubushakashatsi agomba kwishyura ikosa ryo gupimwa ryumuvuduko ukabije wibishoboka, iyo ikaba ari intambwe yingenzi kugirango tumenye neza ko sensor yujuje igishushanyo n’ibisabwa. Rimwe na rimwe, indishyi zirashobora kandi kunoza imikorere rusange ya sensor muri porogaramu.

Offset, kalibrasi ya Calibibasi hamwe nubushuhe bwubushyuhe burashobora kugerwaho numuyoboro muto urwanya firime, ikosorwa na laser mugupakira.

Ubusanzwe sensor ikoreshwa ifatanije na microcontroller, kandi software yashyizwemo na microcontroller ubwayo ishyiraho imibare yimibare ya sensor. Nyuma ya microcontroller isomye ibisohoka voltage, moderi irashobora guhindura voltage mukigero cyo gupima umuvuduko binyuze muguhindura analog-to-digitale.

Icyitegererezo cyibiharuro cyoroshye cya sensor nigikorwa cyo kwimura. Icyitegererezo kirashobora gutezimbere mubikorwa byose bya kalibrasi, kandi gukura kwicyitegererezo biziyongera hamwe no kwiyongera kwingingo.

Urebye kuri metero, ikosa ryo gupima rifite ubusobanuro bukomeye: ryerekana itandukaniro riri hagati yumuvuduko wapimwe nigitutu nyirizina. Nyamara, igitutu nyacyo ntigishobora kuboneka muburyo butaziguye, ariko birashobora kugereranywa no gukurikiza ibipimo byingutu. Ubusanzwe Metrologiste ikoresha ibikoresho bifite ukuri byibuze inshuro 10 kurenza ibikoresho byapimwe nkibipimo byo gupima.

Kuberako sisitemu idahwitse irashobora gukoresha gusa sensibilité na offset indangagaciro kugirango uhindure ibisohoka voltage mumakosa yibitutu.
