Imitha yezinga le-Ultrasonic

Imitha yezinga le-ultrasonic iyithuluzi lokulinganisa elingathintani elilinganisa izinga loketshezi noma izinga lezinto eziwuketshezi noma izinto eziqinile kusetshenziswa isimiso sokubonakaliswa kwe-ultrasonic. Inezici ezilandelayo eziphawulekayo:

1. Ukulinganisa okungathintani nokuguquguquka okunamandla

Inzwa ayixhumani ngqo ne-medium elinganisiwe, igwema izinkinga ezifana nokugqwala, ukunamathela, kanye nokuguguleka okubangelwa yi-medium. Ifaneleka kakhulu ezimweni zokusebenza ezinzima ezifaka amazinga okushisa aphezulu, ukucindezela okuphezulu, izinto ezigqwalisayo (njengezixazululo ze-acid-base), izinto eziqinile (njenge-slurry), noma izinto eziqukethe izinhlayiya eziqinile. Inobungane nezimo ezinezidingo eziphezulu zokuhlanzeka (njengezimboni zokudla nezokwelapha) futhi ngeke ingcolise izinto.

2. Ububanzi bokulinganisa kanye nokuguquguquka okuphezulu

Ububanzi bokulinganisa bungasukela kumashumi amasentimitha kuya kumashumi amamitha (kuye ngokuthi imodeli nezimo zokusebenza zinjani), okungahlangabezana nezidingo zokulinganisa izinga loketshezi/izinga lezinto ezibonakalayo zezimo eziningi zezimboni (njengamathangi okugcina izinto, amakettle okusabela, amachibi okubhukuda, ama-silo, njll.). Indlela yokufaka iyaguquguquka. Ingafakwa phezulu noma ohlangothini lwesitsha nge-bracket ngaphandle kokungena ngokujulile endaweni yokuxhumana, okwenza ukwakhiwa kube lula.

3. Isivinini sokuphendula okusheshayo kanye nokusebenza okuhle ngesikhathi sangempela

Izimpawu ze-Ultrasonic zisakazeka ngesivinini esisheshayo (cishe ama-340m/s emoyeni) ngomjikelezo omfushane wokulinganisa (ngokuvamile kuma-millisecond), okungabonisa izinguquko eziguquguqukayo zezinga lezinto ngesikhathi sangempela. Ifanele ukuqapha ukuguquguquka okusheshayo kwezinga loketshezi/lezinto ezibonakalayo (njengasemishinini yokugcwalisa, ama-silo ashukumisayo, njll.).

4. Ukusebenza okulula kanye nezindleko eziphansi zokulungisa

Asikho isidingo sezakhiwo eziyinkimbinkimbi zemishini, futhi inqubo yokulinganisa ilula (amanye amamodeli asekela ukulinganisa okukodwa). Ukulungiswa kamuva kudinga kuphela ukuhlanzwa njalo kwe-sensor probe ukuze kugwenywe uthuli nomhwamuko wamanzi okuthinta ukudluliswa kwesignali, okuholela ezindleleni zokulungisa eziphansi. Amamodeli amaningi afakwe izibonisi zedijithali noma izixhumi zokuxhumana (njenge-4-20mA, RS485), ezingafunda idatha ngqo noma zixhumeke ohlelweni lokulawula ukuze kube lula ukuqapha kude.

5. Akuthinteki yizakhiwo zomzimba zale nto

Imiphumela yokulinganisa ayithintwa yizakhiwo ezibonakalayo ze-medium njengobuningi, i-viscosity, i-conductivity, kanye nezinga lokushisa (ngaphakathi kwebanga elithile, kudingeka isinxephezelo sokushisa). Uma nje ubuso be-medium bungabonakalisa ngempumelelo amagagasi e-ultrasonic, ukulinganisa okuzinzile kungafinyelelwa.

6. Imikhawulo kanye nezinyathelo zokuphepha

Kuthinteke yizici zemvelo:

Amagagasi e-Ultrasonic asakazeka emoyeni. Uma kunezivunguvungu zomoya ezinamandla, uthuli, umusi, igwebu, noma izithiyo esitsheni (njengezivunguvungu), kungabangela ukubonakaliswa kwesignali okungahlelekile, okuthinta ukunemba kokulinganisa noma okuholela ekwehlulekeni.

Izidingo eziphezulu ze-interface:

Ubuso be-medium elinganisiwe kudingeka bube yisicaba (njengoketshezi olungaguquki). Uma kuyindawo yoketshezi eshintshashintsha kakhulu noma indawo ekhululekile yezinhlayiya eziqinile (njenge-powder silo), amaphutha angase avele ngenxa yezibonakaliso ezibuthakathaka ezibonisiwe.

Umkhawulo wokushisa:

Izindawo ezinokushisa okuphezulu (njengokudlula u-80°C) zingabangela izinguquko ekuminyaneni komoya, okuthinta ijubane lokusabalala kwamaza omsindo. Kubalulekile ukukhetha amamodeli anemisebenzi yokunciphisa ukushisa okuphezulu.

Izinzuzo eziyinhloko zamamitha e-ultrasonic level amamitha ukungathintani, ukumelana nokugqwala, ukufakwa okulula nokugcinwa, kanye nohlu olubanzi lwezicelo. Amadivayisi asetshenziswa kakhulu ekulinganisweni kwezinga/lezinto eziwuketshezi ekukhiqizweni kwezimboni. Kodwa-ke, lapho ukhetha, kufanele kuqashelwe ukugwema ukuzwela kwawo endaweni ezungezile (njengothuli, umusi) kanye nesimo sobuso be-medium. Uma kudingeka, amadivayisi asizayo (njengeziqondiso zamagagasi) noma amamodeli akhethekile (njengezimodeli ezingaqhumi, ezishisa kakhulu) kufanele asetshenziswe ukuze azivumelanise nezimo zokusebenza eziyinkimbinkimbi.
