Ifanelekile kwi-Dongfeng Cummins inzwa yoxinzelelo lweoyile 4928593
Iindidi kunye nokukhethwa kweenzwa zoxinzelelo kunye noxinzelelo loxinzelelo: Izinzwa zoxinzelelo kunye noxinzelelo loxinzelelo zihlulwe zibe yi-gauge pressure, uxinzelelo olupheleleyo kunye noxinzelelo oluhlukeneyo. Amabanga achanekileyo afana no-0.1, 0.2, 0.5 kunye no-1.0. Uluhlu loxinzelelo olunokulinganiswa lubanzi kakhulu, luncinci njengeshumi leemilimitha zekholomu yamanzi kwaye likhulu ngamakhulu e-megapascals. Uluhlu lweqondo lokushisa olusebenzayo lweentlobo ezahlukeneyo zezivamvo zoxinzelelo kunye nezidlulisi zoxinzelelo nazo zahlukile, ezihlala zihlulwe zibe ngamabakala amaninzi: 0 ~ 70 ℃, -25 ~ 85 ℃, -40 ~ 125 ℃ kunye -55 ~ 150 ℃. Ubushushu bokusebenza kwezinye iinzwa zoxinzelelo ezikhethekileyo zinokufikelela kuma-400 ~ 500℃. Izinzwa zoxinzelelo kunye noxinzelelo loxinzelelo zineempawu ezahlukeneyo zokungangeni manzi kunye namabakala obungqina bokuqhuma okusekwe kwizinto ezahlukeneyo kunye noyilo lwesakhiwo. Ngenxa yokwahluka kwezixhobo kunye neemilo, iintlobo zemithombo yeendaba ezinolwelo ezinokulinganiswa kumngxunya wokufumana ulwelo nazo ziyahluka, ezihlala zihlulwe zibe yirhasi eyomileyo, ulwelo oluqhelekileyo, isisombululo se-asidi-base-corrosive, i-gas-liquid evuthayo, i-viscous. kunye nemidiya ekhethekileyo. Njengezixhobo eziphambili, izinzwa zoxinzelelo kunye noxinzelelo loxinzelelo kufuneka zisetyenziswe kunye nezixhobo zesibini okanye iikhompyuter. Iimowudi zobonelelo lwamandla eziqhelekileyo zezivamvo zoxinzelelo kunye nabathumeli boxinzelelo zezi: DC5V, 12V, 24V, 12V, njl., kunye neendlela zokukhupha ezi: 0~5V, 1~5V, 0.5~4.5V, 0~10mA.0~20mA .4 ~ 20mA, njl., kunye nojongano neekhompyuter ezinjenge-Rs232 kunye ne-Rs485. Xa ukhetha i-sensor sensors kunye ne-pressure transmitters, abasebenzisi kufuneka baqonde ngokupheleleyo iimeko zokusebenza zenkqubo yokulinganisa uxinzelelo, kwaye benze ukhetho olufanelekileyo ngokweemfuno, ukwenzela ukuba inkqubo isebenze kwimeko engcono kwaye iindleko zeprojekthi zingancitshiswa. Iiparamitha ezichanekileyo eziqhelekileyo zenzwa yoxinzelelo kunye nezixhobo zokuvavanya Isixhobo sokulinganisa i-Static ye-sensor: i-piston manometer: ukuchaneka kungcono kune-0.05%; I-manometer yedijithali: ukuchaneka kungcono kune-0.05%; Unikezelo lwamandla olulawulwa yi-DC: ukuchaneka kubhetele kuno-0.05%; isixhobo sokuhlola ubushushu bobushushu: igumbi lovavanyo lobushushu obuphezulu: ukuchaneka kokulawula ubushushu yi-1℃; igumbi lokuvavanya ubushushu obuphantsi: ubushushu bunokuba ukusuka ku-0℃ ukuya kwi-60℃. Izinto zovavanyo lwe-Sensor yendalo esingqongileyo: i-zero yeqondo lobushushu, ukukhukuliseka, i-zero hysteresis, i-hysteresis enovakalelo. (Jonga ukulungelelaniswa kwemveliso kwiqondo lokushisa ngaphakathi kweqondo lokushisa elichaziweyo. Le parameter ibaluleke kakhulu ekuchanekeni.) Izilumkiso zokusetyenziswa kweenzwa zoxinzelelo Izinzwa zoxinzelelo kunye noxinzelelo loxinzelelo kufuneka zifunde iisampulu zemveliso kunye nemiyalelo yokusebenza ngokweenkcukacha ngaphambi kokufakwa, kwaye i-interface yoxinzelelo ayifanele ivuze ngexesha lofakelo ukuqinisekisa uluhlu oluchanekileyo kunye neengcingo. Ngokuqhelekileyo, iindawo zokuhlala zezivamvo zoxinzelelo kunye noxinzelelo loxinzelelo kufuneka zibekwe phantsi. Iintambo zomqondiso akufuneki zidityaniswe neentambo zombane, kwaye uphazamiseko olomeleleyo lwe-electromagnetic kufuneka luthintelwe malunga nezinzwa zoxinzelelo kunye nezidluliseli zoxinzelelo. Izinzwa zoxinzelelo kunye noxinzelelo loxinzelelo ziya kuqinisekiswa ngamaxesha athile ngokwemigaqo yoshishino esetyenziswayo.
