1. Intshayelelo yeMveliso
Imitha yenqanaba le-ultrasonic yothotho lwe-LMUsisixhobo sokulinganisa esidibeneyo esineentambo ezimbini esasungulwa yiLanry Instruments. Siqulathe i-probe sensor edibeneyo kunye neyunithi yokucubungula nge-elektroniki enesakhiwo esivaliweyo esingenako ukuvuza, esivumela ukujonga rhoqo amanqanaba angadibaniyo kwizinto ezimanzi kunye nezinto eziqinileyo. Ifanelekile kwiimeko ezinzima zokusebenza kwi-metallurgy, iikhemikhali, amandla ombane, ipetroliyam kunye namanye amashishini, le mveliso ixhasa ukufakwa kwezikrufu kunye neflange. Isebenzisa umgaqo wokulinganisa ixesha lokubhabha ovuthiweyo, ixhotyiswe ngembuyekezo yobushushu ngokuzenzekelayo kunye netekhnoloji yokucubungula isignali ekrelekrele, ikhupha ngokuzinzileyo imiqondiso ye-analog ye-4-20mA esemgangathweni, isebenza njengesisombululo esiqhelekileyo sokujonga amanqanaba etanki kunye ne-silo.
Uthotho lwe-LMUIquka iimodeli ezisixhenxe ezihlelwe ngokweenqanaba eliphezulu lokulinganisa: i-LMU4, i-LMU6, i-LMU8, i-LMU12, i-LMU15, i-LMU20 kunye ne-LMU30, kunye neenqanaba zokulinganisa ulwelo ezigubungela i-4m ukuya kwi-30m. Kwizinto eziqinileyo, amaza e-ultrasonic asasazeka lula kwaye afunxwe yimpuphu, ngoko ke uluhlu lokulinganisa olusebenzayo yi-50% kuphela yaloo meko yokusebenza kolwelo. Ukukhethwa kwemodeli kuya kuhambelana nendawo yokufakela kwindawo kunye neempawu zezinto. Iyunithi yonke ifikelela kwinqanaba lokukhusela le-IP67; isigqubuthelo sayo sangaphandle sesinyithi sinomoya ongenamoya kunye nokumelana ne-alkali, okuvumela ukusebenza okuzinzileyo kwexesha elide phantsi koxinzelelo oluqhelekileyo lwe--40℃ ~ 80℃ kunye ne-±0.1MPa.
2. Umgaqo-siseko wokulinganisa
Esi sixhobo sigqibezela ukulinganisa umgama ngeindlela ye-acoustic yexesha lokubhabha: i-sensor ikhupha ii-pulses ze-ultrasonic ezantsi. Emva kokubetha umphezulu wezinto, amaza esandi abuyela kwi-probe. Imitha irekhoda ixesha eliphakathi kwe-t phakathi kokudluliselwa kunye nokwamkelwa, kwaye ibala umgama D ukusuka kwi-probe ukuya kumphezulu wezinto kunye nesantya sesandi c, ilandela le fomyula: D=c·t/2.
Abaqhubi bafaka ubude bokufakelwa obupheleleyo u-H (umgama wetanki engenanto) wetanki kwangaphambili, kwaye imitha iguqula ngokuzenzekelayo inqanaba lexesha langempela u-L=HD. I-sensor yobushushu edibeneyo eyakhelwe ngaphakathi ihlaziya ukuphambuka kwesantya sesandi okubangelwa kukutshintsha kobushushu ngexesha langempela ukuze kupheliswe iimpazamo zokulinganisa ezivela kubushushu obungqongileyo.
Esi sixhobo sinomgama ongenanto (indawo efileyo B), apho ii-echoes zingenakubonwa khona. Iseti epheleleyo yesikali F ngexesha lokulinganisa akufuneki idlulele kumgama ongenanto. Umgama ongenanto wemodeli nganye uyanda ukusuka kwi-0.2m ukuya kwi-1.2m, kwaye iimodeli zomgama omde zifuna indawo enkulu yokufaka ebekelwe bucala. Kufuneka kufakwe iiseti ezimbini kuphela zeeparameter (ukuphakama kwetanki engenanto kunye nesikali esipheleleyo) ukuze kulinganiswe ngokukhawuleza. Amaqhosha amathathu okungenisa kunye nesiboniso esikhulu se-LCD esineenombolo ezi-4 zixhasa ukulungisa nokufunda okulula kwindawo.
3. Iimpawu zeMveliso eziPhambili
- Uyilo oludibeneyo oludibeneyo: I-sensor kunye neyunithi ye-elektroniki zidityaniswe njengento enye, kunye neendlela zokufaka izikrufu/iflange ukuze kube lula ukuyiqhaqha nokuyifakela ngaphandle kwentambo eyahlukileyo.
- Ukhuseleko lwe-multi-circuit: Iimodyuli zokukhusela i-overvoltage eyakhelwe ngaphakathi, i-overcurrent kunye ne-lightning, ezizivumelanisa neemeko zombane ezintsonkothileyo kwiifektri.
- Ubuchule obugqwesileyo bokulwa nokuphazamiseka: Izihluzi ze-algorithm zesignali yedijithali ezikrelekrele ezidityanisiweyo eziveliswa ngumphunga, uthuli, izixhasi zeetanki kunye neziqhushumbisi, zilungisa iimeko zokusebenza kwetanki ezintsonkothileyo.
- Isiphumo esiqhelekileyo sesignali: Isiphumo sangoku se-4-20mA esinomthamo womthwalo we-0~500Ω, esinokuqhagamshelwa ngqo kwi-PLC, iirekhoda kunye nezinye izixhobo zolawulo lwemizi-mveliso; i-4mA ihambelana netanki engenanto ngelixa i-20mA ihambelana netanki epheleleyo.
- Ukuziqhelanisa neemeko zokusebenza ngokubanzi: Indlu ye-elektroniki yesinyithi, i-ABS sensor probe, i-IP67 engangeni luthuli, ukusebenza okungangeni manzi kunye nokungangeni kwe-alkali, kusebenza kwiindawo eziphantsi/eziphezulu kunye neendawo ezixinezelekileyo kancinci.
