Iitransmitter zoxinzelelo zizixhobo ezibalulekileyo zokulinganisa kwicandelo lolawulo lwenkqubo. Kwiisetingi ze-automation zemizi-mveliso, iinjineli zihlala zifuna ukujonga imiba "yokushukuma kwe-zero" kwiitransmitter zoxinzelelo kwaye zenze ukulinganiswa kwe-zero ngokufanelekileyo. Ukushukuma kwe-zero kubhekisa kwinto apho isignali yokuphuma kwesixhobo sokulinganisa ijika kancinci kancinci kwi-zero point yethiyori ngokuhamba kwexesha okanye ngenxa yotshintsho lokusingqongileyo xa igalelo liyi-zero (akukho bungakanani bomzimba obulinganisiweyo obusetyenziswayo). Umzekelo, itransmitter yoxinzelelo enoluhlu lwe-0~10 MPa kufuneka ikhuphe i-4 mA (kwi-4~20 mA output) xa ivezwe kuxinzelelo lomoya (uxinzelelo lwe-zero gauge). Ukushukuma kwe-zero kwenzeka xa isiphumo sokwenyani sijika kancinci kwaye rhoqo kweli xabiso. Iimpazamo ezicwangcisiweyo zingeniswa ngokuthe ngqo ezichaphazela ukuchaneka kokulinganisa kunye nokuchaneka kolawulo.
Kutheni iiPressure Transmitters zisengozini yokungaqhubi kakuhle?
Umgaqo woLinganiselo:Iitransmitter zoxinzelelo zihlala zisebenza ngokusekelwe ekuguqukeni kwento elastiki, okubandakanya ukudluliselwa koxinzelelo ngokwasemzimbeni. Le nkqubo inokuchatshazelwa zizinto ezifana nendawo yokufakela kunye neempawu eziphakathi, ezikhokelela ekuphambukeni kwinqaku le-zero.
Iimfuneko zokusetyenziswa:Iitransmitter zoxinzelelo kunye nomahluko zihlala zifuna ukuziqhelanisa neendawo ezahlukeneyo zokufakela kunye neemeko zokulinganisa kwizicelo zoshishino. Umzekelo, xa kulinganiswa inqanaba lolwelo kwitanki evaliweyo, ukuxinana kwe-gas phase medium kunokuvumela ukuxinana ukuba kungene kwimigca ye-impulse kunye necala elingaphantsi letransmitter, okubangela iimpazamo zokulinganisa. Kwiimeko ezinjalo, kufuneka ukufuduka okungalunganga okutshintsha inqaku le-zero yetransmitter ukuba iqale kuxinzelelo olungalunganga lomahluko ukuze kuhlangatyezwane neemfuno zokusebenza.
Ukuvezwa kwezinto:Izinto ezithintela uxinzelelo (ezifana nee-diaphragms zokwahlukanisa) zidibana ngqo ne-medium elinganisiweyo. Ukubola, ukwakheka, impembelelo yamasuntswana okanye ukunamathela kwe-medium exineneyo kunokutshintsha iimpawu zazo zoomatshini, nto leyo ekhokelela kutshintsho lwe-zero point.
Izinto eziphathelele indalo:Ukuqina kwebholiti okungalinganiyo ngexesha lokufakelwa, uxinzelelo loomatshini oluvela ekukhuleni kobushushu bepayipi kunye nokucutheka okanye uxinzelelo oluphezulu lwe-static (kwii-DP transmitters) kunokubangela ukuguquka kwe-diaphragm yokuva uxinzelelo, okubangela iimpazamo eziqhubekayo ze-static. Ukutshintshatshintsha kobushushu kunye nokungcangcazela kwindawo nako kunokuba nemiphumo enzima ngakumbi.
Ungayijonga njani iZero Drift kwiiPressure Transmitters?
Ukungashukumi kakuhle yingxaki eqhelekileyo kwiitransmitter zoxinzelelo kwaye kufuna amanyathelo obuchwephesha ahlukeneyo ukunciphisa:
Uvavanyo lweFektri kunye noLungiso:Yenza uvavanyo olucokisekileyo lobushushu obuphantsi kakhulu kunye noxinzelelo olungashukumiyo ngexesha lokuvelisa, ugcine idatha yembuyekezo kwisithumeli ukuze kulungiswe ngexesha langempela.
Ukuphuculwa kwezinto kunye neenkqubo:Faka izinto ezithambileyo ezinamandla okudinwa aphezulu kunye nozinzo oluhle lobushushu (iHastelloy, ii-diaphragms zeseramikhi, njl.njl.) kwaye uphucule iinkqubo zonyango lobushushu ukuze unciphise uxinzelelo lwangaphakathi.
Ukugcinwa rhoqo kunye nokulinganiswa:Misela imijikelo yokulinganisa ngokusekelwe kwiimeko zokusebenza kwaye wenze uhlengahlengiso kwindawo phantsi kweemeko ze-zero.
Ufakelo oluphuculweyo kunye nokusetyenziswa:Kuphephe ukuqinisa kakhulu, sebenzisa izibiyeli ukuze uhlukanise uxinzelelo lombhobho kwaye uthintele ukuqina okuphakathi okanye ukwakheka kwekristale.
