Imitha yenqanaba le-Ultrasonic

Imitha yenqanaba le-ultrasonic sisixhobo sokulinganisa esingadibaniyo nesilinganisa inqanaba lolwelo okanye inqanaba lezinto ezimanzi okanye izinto eziqinileyo sisebenzisa umgaqo wokubonakaliswa kwe-ultrasonic. Ineempawu ezilandelayo eziphawulekayo:

1. Ukulinganisa okungadibaniyo kunye nokuzivumelanisa nezimo okunamandla

Isensor ayidibani ngqo nesixhobo esilinganisiweyo, nto leyo ethintela imiba efana nokugqwala, ukunamathela, kunye nokuguguleka okubangelwa sisixhobo. Ifanelekile ngokukodwa kwiimeko ezinzima zokusebenza ezibandakanya amaqondo obushushu aphezulu, uxinzelelo oluphezulu, izinto ezirhabaxa (ezifana nezisombululo ze-asidi), izinto ezixineneyo (ezifana nodaka), okanye izinto eziqulethe amasuntswana aqinileyo. Ilungele iimeko ezineemfuno eziphezulu zococeko (ezifana nemizi-mveliso yokutya kunye namayeza) kwaye ayizukungcolisa izinto.

2. Uluhlu olubanzi lokulinganisa kunye nokuguquguquka okuphezulu

Uluhlu lokulinganisa lunokuba ngamashumi eesentimitha ukuya kumashumi eemitha (kuxhomekeke kwimodeli kunye neemeko zokusebenza), nto leyo enokuhlangabezana neemfuno zokulinganisa umgangatho wolwelo/inqanaba lezinto ezibonakalayo kwiimeko ezininzi zoshishino (ezifana neetanki zokugcina, iikettle zokusabela, amachibi, ii-silos, njl.njl.). Indlela yokufaka iguquguquka. Ingafakwa phezulu okanye ecaleni kwesikhongozeli ngebracket ngaphandle kokungena nzulu kwi-medium, okwenza ulwakhiwo lube lula.

3. Isantya sokuphendula esikhawulezayo kunye nokusebenza kakuhle ngexesha langempela

Imiqondiso ye-Ultrasonic isasazeka ngesantya esikhawulezayo (malunga ne-340m/s emoyeni) ngomjikelo omfutshane wokulinganisa (ngesiqhelo kwi-milliseconds), onokubonakalisa utshintsho oluguquguqukayo lwenqanaba lezinto ngexesha langempela. Ifanelekile ukujonga ukuguquguquka okukhawulezayo kwenqanaba lolwelo/lezinto (ezifana noomatshini bokugcwalisa, ii-silos eziguquguqukayo, njl.njl.).

4. Ukusebenza okulula kunye neendleko eziphantsi zokulungisa

Akukho mfuneko yezakhiwo ezintsonkothileyo zoomatshini, kwaye inkqubo yokulinganisa ilula (ezinye iimodeli zixhasa ukulinganisa okunesitshixo esinye). Ukugcinwa kamva kufuna kuphela ukucocwa rhoqo kweprobe yesensor ukuze kuthintelwe uthuli kunye nomphunga wamanzi ochaphazela ukuhanjiswa kwesignali, nto leyo ebangela iindleko zokulungisa eziphantsi. Uninzi lweemodeli zixhotyiswe ngemiboniso yedijithali okanye ii-interface zonxibelelwano (ezifana ne-4-20mA, RS485), ezinokufunda idatha ngqo okanye ziqhagamshele kwinkqubo yolawulo ukuze kube lula ukujonga kude.

5. Ayichaphazeleki ziimpawu zomzimba zesixhobo

Iziphumo zokulinganisa azichaphazeleki ziimpawu zomzimba zesixhobo esifana noxinano, i-viscosity, i-conductivity, kunye nobushushu (ngaphakathi koluhlu oluthile, kufuneka imbuyekezo yobushushu). Ukuba nje umphezulu wesixhobo unokubonakalisa ngempumelelo amaza e-ultrasonic, umlinganiselo ozinzileyo unokufezekiswa.

6. Imida kunye neendlela zokuzikhusela

Ichatshazelwa zizinto ezisingqongileyo:

Amaza e-ultrasonic asasazeka emoyeni. Ukuba kukho imisinga yomoya enamandla, uthuli, umphunga, igwebu, okanye imiqobo kwisitya (ezifana nezivuseleli), oku kunokubangela ukubonakaliswa kwesignali okungahambelaniyo, okuchaphazela ukuchaneka kokulinganisa okanye okukhokelela ekusileleni.

Iimfuno eziphezulu ze-interface:

Umphezulu wesixhobo esilinganisiweyo kufuneka ube tyaba (njengolwelo olungashukumiyo). Ukuba ngumphezulu wolwelo otshintshatshintsha ngamandla okanye umphezulu okhululekileyo wamasuntswana aqinileyo (njengesilo somgubo), iimpazamo zinokwenzeka ngenxa yemiqondiso ebonakalisiweyo ebuthathaka.

Umlinganiselo wobushushu:

Iindawo ezinobushushu obuphezulu (ezifana nokudlula i-80°C) zinokubangela utshintsho kubuninzi bomoya, nto leyo echaphazela isantya sokusasazeka kwamaza esandi. Kubalulekile ukukhetha iimodeli ezinemisebenzi yokuhlawula ubushushu obuphezulu.

Iingenelo eziphambili zeemitha zezinga le-ultrasonic kukungachukumisi, ukumelana nokugqwala, ukulula kokufakela nokugcina izinto zisemgangathweni, kunye noluhlu olubanzi lwezicelo. Zizixhobo ezisetyenziswa rhoqo ekulinganiseni izinga lezinga/lezinto zolwelo kwimveliso yemizi-mveliso. Nangona kunjalo, xa ukhetha, kufuneka kuqwalaselwe ukuphepha ubuthathaka bazo kwindalo esingqongileyo (njengothuli, umphunga) kunye nemeko yomphezulu wesixhobo. Ukuba kuyimfuneko, izixhobo ezincedisayo (ezifana nezikhokelo zamaza) okanye iimodeli ezikhethekileyo (ezifana nemodeli ezimelana nokuqhuma, ezinobushushu obuphezulu) kufuneka zisetyenziswe ukuze zilungelelanise iimeko zokusebenza ezinzima.
