ISikhokelo sokugqibela sokuKhetha iSilicon yoShicilelo olusasazekileyo loThutho
Phakathi kweentlobo ezininzi zokuhambisa uxinzelelo-kubandakanya i-ceramic, i-capacitive, kunye ne-monocrystalline silicon variants-i-diffused silicon pressure transmitters ibe sesona sisombululo samkelwe ngokubanzi kwizicelo zokulinganisa kwimizi-mveliso.
Ukusuka kwi-oyile kunye negesi ukuya ekusetyenzweni kweekhemikhali, ukuveliswa kwentsimbi, ukuveliswa kwamandla, kunye nobunjineli bokusingqongileyo, aba bathumeli bahambisa iliso elithembekileyo nelichanekileyo loxinzelelo kuxinzelelo lwegeyiji, uxinzelelo olupheleleyo, kunye nokusetyenziswa kwevacuum.
Yintoni iSilicon yoShicilelo olusasaziweyo loThutho?
Itekhnoloji yavela phakathi kwiminyaka yoo-1990 xa iNovaSensor (USA) yayiphayona iidiaphragm zesilicon ezinomatshini odityaniswe ngeglasi. Le mpumelelo idale i-compact, izinzwa ezichaneke kakhulu ezinokuphinda-phinda okukhethekileyo kunye nokuxhathisa umhlwa.
Umgaqo wokuSebenza
- Uxinzelelo lwenkqubo luthumela nge-diaphragm eyedwa kunye neoli ye-silicone kwi-silicon diaphragm
- Uxinzelelo lwereferensi (i-ambient okanye ivacuum) isebenza kwelinye icala
- Iziphumo zokuphambuka zichongiwe yibhulorho yeWheatstone yeegeji zoxinzelelo, ukuguqula uxinzelelo lube luphawu lombane.
8 Iinqobo zoKhetho eziBalulekileyo
1. IMeasured Medium Compatibility
Isixhobo senzwa kufuneka sihambelane neekhemikhali kunye neempawu zomzimba zenkqubo yakho yolwelo:
- Uyilo oluqhelekileyo lusebenzisa i-316L i-diaphragm yensimbi engenasici kwizicelo ezininzi
- Ngolwelo oludlekayo okanye olukhazimlayo, cacisa ii-diaphragm ezigungxulwayo
- Izinketho zebakala lokutya ziyafumaneka kwizicelo zamachiza kunye neziselo
- Imithombo yeendaba ene-viscosity ephezulu (udaka, udaka, iasphalt) ifuna uyilo lwediaphragm egungxulwayo engenamngxunya.
2. UKhetho lweRange loxinzelelo
Uluhlu olukhoyo lususela kwi -0.1 MPa ukuya kwi-60 MPa. Soloko ukhetha uluhlu lwama-20-30% ngaphezulu kunoxinzelelo lwakho oluphezulu lokusebenza ukuthintela ukugcwala.
Isikhokelo soGuqulo lweYunithi yoxinzelelo
| Iyunithi | Ixabiso elilinganayo |
|---|---|
| 1 MPa | 10 bar / 1000 kPa / 145 psi |
| 1 ibha | 14.5 psi / 100 kPa / 750 mmHg |
Igeyiji vs. Uxinzelelo olupheleleyo:Iimbekiselo zoxinzelelo lwegeyiji yoxinzelelo lwe-ambient (zero ilingana nomoya), ngelixa iimbekiselo zoxinzelelo olupheleleyo zisivacuum. Kwizicelo zobude obuphezulu, sebenzisa izinzwa zegeyiji ephuma umoya ukuhlawula iatmospheri yasekhaya eyahlukahlukileyo.
Ukuqwalaselwa kweSicelo esiKhethekileyo
Umlinganiselo wegesi ye-ammonia
Cacisa i-diaphragm efakwe ngegolide okanye i-anti-corrosive coatings ezikhethekileyo ukukhusela ukuthotywa kwenzwa kwinkonzo ye-ammonia. Qinisekisa ukuba indlu yothumelo lwezindlu idibana ne-NEMA 4X okanye i-IP66 yohlengahlengiso lofakelo lwangaphandle.
Ufakelo lweNdawo enobungozi
Ngeendawo ezinokutsha okanye ezinogqabhuko-dubulo:
- Cela ioli ene-fluorinated (FC-40) endaweni yokuzaliswa kweoli ye-silicone eqhelekileyo
- Qinisekisa iziqinisekiso zokhuseleko lwangaphakathi (Ex ia) okanye olungatshiyo (Ex d) izicelo
- Ukuqinisekisa ukubekwa komhlaba okufanelekileyo kunye nofakelo lomqobo ngokwemigangatho ye-IEC 60079
Ukuqukumbela
Izithutha zoxinzelelo lwe-silicon ezisasazekileyo zibonelela ngolungelelwaniso oluchanekileyo lokuchaneka, ukuqina, kunye nokuguquguquka kuzo zonke iinkqubo zamashishini. Ukhetho olufanelekileyo-ukusuka kuvavanyo lokuhambelana kweendaba ukuya kwinkcazo yesignali yemveliso-uqinisekisa ukuchaneka komlinganiselo kunye nokuthembeka kwexesha elide.
Nokuba kubeka iliso kwimigca yomphunga woxinzelelo oluphezulu, ukulawula ukusabela kweekhemikhali, okanye ukuqinisekisa ukuphathwa ngokukhuselekileyo kwe-ammonia, ulungelelwaniso lokuhambisa oluchanekileyo luphucula ukusebenza kakuhle kwenkqubo kunye nokhuseleko lokusebenza.
