Twese tuzi ko igice cy'ingenzi cy'umunzani w'ikoranabuhanga ariakazu ko gushyiramo ibintu, byitwa "umutima" w'igikoresho cy'ikoranabuhangaigipimo. Bishobora kuvugwa ko ubuhanga n'ubushobozi bwa sensor bigena mu buryo butaziguye imikorere y'igipimo cy'ikoranabuhanga. None se twahitamo dute agace k'umutwaro? Ku bakoresha bacu muri rusange, ibipimo byinshi by'agace k'umutwaro (nk'ubudahuza, hysteresis, creep, ingano y'ubushyuhe, ubwiyongere bw'ubushyuhe, n'ibindi) bituma tunanirwa cyane. Reka turebe imiterere ya sensor y'igipimo cy'ikoranabuhanga. kuri tibipimo by'ingenzi bya tekiniki.
(1) Umutwaro upimwe: umutwaro ntarengwa wo mu gice cy'imbere cy'umurambararo (axial load) sensor ishobora gupima mu rugero rwa tekiniki rwagenwe. Ariko mu mikoreshereze nyayo, muri rusange 2/3 ~ 1/3 by'urugero rwagenwe ni byo bikoreshwa.
(2) Umutwaro wemewe (cyangwa umutwaro uremereye): umutwaro ntarengwa wemewe n'akazu k'umutwaro. Gukora cyane byemewe mu rugero runaka. Muri rusange 120% ~ 150%.
(3) Umutwaro ntarengwa (cyangwa umutwaro urenze urugero): umutwaro ntarengwa w’umurongo ugenga icyuma gipima ikoranabuhanga gishobora kwihanganira kitagitakaje ubushobozi bwacyo bwo gukora. Ibi bivuze ko icyuma gipima amashanyarazi kizangirika iyo akazi karenze iki gipimo.
(4) Ubushobozi bwo gupima: Igipimo cy'ubwiyongere bw'umusaruro ugera ku bwiyongere bw'umutwaro ukoreshwa. Ubusanzwe mV y'umusaruro upimwe kuri 1V y'ubwiyongere.
(5) Kudahuza: Iki ni igipimo kigaragaza neza isano iri hagati y’umusaruro w’ikimenyetso cy’amashanyarazi gitangwa na sensor y’ubunini bw’amashanyarazi n’umutwaro.
(6) Gusubiramo: Gusubiramo bigaragaza niba agaciro k'umusaruro wa sensor gashobora gusubirwamo kandi gahoraho iyo umutwaro umwe ukoreshejwe inshuro nyinshi mu bihe bimwe. Iki kintu ni ingenzi cyane kandi gishobora kugaragaza neza ubwiza bwa sensor. Ibisobanuro by'ikosa ryo gusubiramo mu gipimo cy'igihugu: ikosa ryo gusubiramo rishobora gupimwa hakoreshejwe uburyo butari bwo icyarimwe n'itandukaniro ntarengwa (mv) hagati y'agaciro k'ikimenyetso nyacyo cy'umusaruro gapimwe inshuro eshatu ku gice kimwe cy'igerageza.
(7) Gutinda: Igisobanuro gikunzwe cya hysteresis ni: iyo umutwaro ushyizwemo intambwe ku yindi hanyuma ugakurwamo, bihuye na buri mutwaro, byaba byiza hagomba kubaho igipimo kimwe, ariko mu by'ukuri birahuye, urwego rwo kudahuza rubarirwa hakoreshejwe ikosa rya hysteresis. Ikimenyetso cyo kwerekana. Ikosa rya hysteresis ribarwa mu gipimo cy'igihugu ku buryo bukurikira: itandukaniro ntarengwa (mv) hagati y'ikigereranyo cy'umubare w'agaciro nyako k'ikimenyetso cy'umusaruro w'imirongo itatu n'ikigereranyo cy'umubare cy'agaciro nyako k'ikimenyetso cy'umusaruro w'imirongo itatu iri hejuru ku gice kimwe cy'igerageza.
(8) Gusubirana ubwiyongere bw'amajwi n'amajwi: Ikosa ryo guhindagurika kw'amajwi rya sensor rigomba kugenzurwa mu bintu bibiri: kimwe ni uguhindagurika: umutwaro ugenwe ushyirwa ku gipimo nta ngaruka mu masegonda 5-10, n'amasegonda 5-10 nyuma yo gusohora.. Fata ibyasomwe, hanyuma wandike agaciro k'ibyavuye mu bushakashatsi Uburyo bukurikiranye mu bihe bisanzwe mu gihe cy'iminota 30. Icya kabiri ni ukwisubiramo kw'ibintu: gukuraho umutwaro wagenwe vuba bishoboka (mu masegonda 5-10), uhite usoma mu masegonda 5-10 nyuma yo gupakurura, hanyuma wandike agaciro k'umusaruro mu bihe runaka mu minota 30.
(9) Ubushyuhe bwemewe bwo gukoreshwa: bugaragaza ibihe bireba iyi selile y'umutwaro. Urugero, sensor isanzwe y'ubushyuhe muri rusange irangwa nka: -20℃- +70℃Ibikoresho bipima ubushyuhe bwinshi byanditseho ibi bikurikira: -40°C - 250°C.
(10) Ingano y'ubushyuhe: Ibi bigaragaza ko sensor yishyuwe muri urwo rugero rw'ubushyuhe mu gihe cyo kuyikora. Urugero, sensor zisanzwe z'ubushyuhe muri rusange zirangwa nka -10°C - +55°C.
(11) Ubudahangarwa bw'ubushyuhe: agaciro k'ubudahangarwa bw'ubushyuhe hagati y'igice cy'uruziga rwa sensor n'umuraba wa elastic, uko ari munini ni ko ingano y'ubudahangarwa bw'ubushyuhe igira ingaruka ku mikorere ya sensor. Iyo ubudahangarwa bw'ubushyuhe buri hasi y'agaciro runaka, ikiraro ntigikora neza.
