Imagwira pa Cat 330D/336D mafuta pressure sensor EX2CP54-12

Sensa yothamanga imakhala ndi zolondola kwambiri komanso zolakwika zomveka, ndipo kubwezeredwa kolakwika kwa sensor yokakamiza ndiye chinsinsi chakugwiritsa ntchito kwake. Sensor yokakamiza imaphatikizanso cholakwika chochotsa, cholakwika cha sensitivity, cholakwika cha mzere ndi cholakwika cha hysteresis. Pepalali liwonetsa momwe zolakwa zinayizi zimagwirira ntchito komanso momwe zimakhudzira zotsatira za mayeso, komanso nthawi yomweyo kuwonetsa njira yoyezera kukakamiza ndi zitsanzo zogwiritsira ntchito kuti muyezedwe molondola.

Pakalipano, pali mitundu yambiri ya masensa pamsika, zomwe zimathandiza akatswiri opanga mapangidwe kuti asankhe makina okakamiza omwe amafunikira dongosolo. Masensa awa samaphatikizapo otembenuza ofunikira kwambiri, komanso masensa ovuta kwambiri ophatikizika okhala ndi ma pa-chip. Chifukwa cha kusiyana kumeneku, wopanga makinawo ayenera kubweza cholakwika cha kuyeza kwa sensor yokakamiza momwe angathere, chomwe ndi sitepe yofunika kwambiri yowonetsetsa kuti sensa imakwaniritsa zofunikira zopangira ndikugwiritsa ntchito. Nthawi zina, kubweza kumathanso kupititsa patsogolo magwiridwe antchito a sensor mu pulogalamuyo.

Offset, ma calibration osiyanasiyana ndi kulipidwa kwa kutentha zitha kuzindikirika ndi netiweki yopyapyala yopinga mafilimu, yomwe imakonzedwa ndi laser pakuyika.

Sensa nthawi zambiri imagwiritsidwa ntchito kuphatikiza ndi microcontroller, ndipo pulogalamu yophatikizidwa ya microcontroller yokha imakhazikitsa masamu a sensor. Microcontroller ikawerenga mphamvu yotulutsa, fanizoli limatha kusintha voteji kukhala muyeso woyezera kuthamanga kudzera pakusintha kwa chosinthira cha analog-to-digital.

Chitsanzo chosavuta cha masamu cha sensa ndi ntchito yosinthira. Chitsanzocho chikhoza kukonzedwanso mu ndondomeko yonse yowonetsera, ndipo kukhwima kwa chitsanzo kudzawonjezeka ndi kuwonjezeka kwa mfundo za calibration.

Kuchokera pamalingaliro a metrology, cholakwika choyezera chimakhala ndi tanthauzo lolimba kwambiri: limayimira kusiyana pakati pa kuthamanga koyezera ndi kuthamanga kwenikweni. Komabe, kupanikizika kwenikweni sikungapezeke mwachindunji, koma kungayesedwe potsatira miyezo yoyenera yokakamiza. Akatswiri a metrologist nthawi zambiri amagwiritsa ntchito zida zomwe kulondola kwake kumakhala kokulirapo kuwirikiza ka 10 kuposa zida zoyezera ngati miyezo yoyezera.

Chifukwa dongosolo losawerengeka limatha kugwiritsa ntchito kukhudzika kwanthawi zonse ndikusinthira ma voliyumu otulutsa kukhala cholakwika champhamvu.
