Amfani da rashin amfani da mitar matakin radar idan aka kwatanta da mitar matakin ultrasonic

Radarmitar matakinkuma mita matakin ultrasonic ana amfani da su ne a matsayin kayan aikin auna matakin radar, waɗannan su ne fa'idodi da rashin amfanin mita matakin radar idan aka kwatanta da mita matakin ultrasonic:
fa'ida
Daidaiton ma'auni mai girma: na'urar auna matakin radar tana amfani da ƙa'idar tunani na microwave don aunawa, wanda canje-canje a zafin jiki, matsin lamba, yawa, danshi da sauran hanyoyin sadarwa ba ya shafar shi, kuma daidaiton ma'auni yana da girma, gabaɗaya har zuwa ± 1mm ​​ko ma sama da haka. Daidaiton ma'aunin na'urar auna matakin ultrasonic yana da matuƙar tasiri ta hanyar abubuwa kamar halayen matsakaici da zafin jiki na yanayi, kuma daidaito yawanci yana kusan ± 3mm-± 5mm.
Faɗin aikace-aikace masu faɗi
Matsakaicin daidaitawa: Mita matakin radar na iya auna matakin ruwa na abubuwa daban-daban na ruwa da abubuwa masu ƙarfi, gami da lalata, ƙazanta, sauƙin crystallization da sauran kafofin watsa labarai na musamman. Lokacin auna matsakaicin tare da babban danko, sauƙin crystallization ko kumfa, mita matakin ultrasonic na iya samun raguwar sigina ko kuma rashin daidaituwar tunani.
Yanayin zafin jiki mai yawa da matsin lamba mai yawa: mitar matakin radar na iya aiki cikin kwanciyar hankali a cikin yanayi mai tsauri na zafin jiki mai yawa (har zuwa 400℃ ko fiye) da matsin lamba mai yawa (har zuwa 40MPa ko fiye). Saboda iyakancewar kayan transducer da ƙa'idar, kewayon aikace-aikacen mitar matakin ruwa na ultrasonic a cikin yanayin zafi mai yawa da matsin lamba mai yawa yana da ɗan kunkuntar.
Babban zango: Matsakaicin ma'aunin mitar matakin radar yana da girma, wanda gabaɗaya zai iya kaiwa mita goma ko ma ɗaruruwan mita, kuma ya dace da auna matakin ruwa na manyan tankunan ajiya da dogayen hasumiyai. Matsakaicin ma'aunin mitar matakin ultrasonic yawanci yana cikin mita goma.
Ƙarfin ƙarfin hana tsangwama: siginar microwave da mitar matakin radar ke fitarwa ba ta shiga cikin raƙuman lantarki na waje, raƙuman sauti da sauran sigina ba, kuma siginar tana da karko kuma abin dogaro. A cikin yanayi mai ƙarfi tare da hayaniya, girgiza ko tururi, mitar matakin ultrasonic tana da saurin shiga tsakani, wanda ke haifar da ƙaruwar kuskuren aunawa.
Bukatun shigarwa ba su da yawa: na'urar auna matakin radar ba ta da saurin kamuwa da cikas da abubuwan da ke tayar da hankali a cikin akwati lokacin da aka shigar da ita, matuƙar ba a toshe eriya ba. Na'urar auna matakin ultrasonic ba ta buƙatar wani cikas sama da matakin ruwa, in ba haka ba zai shafi yaɗuwar da kuma nuna raƙuman sauti, wanda hakan zai haifar da aunawa mara daidai.
Matsayi na ƙasa
Babban farashi: Abubuwan fasaha na na'urar auna matakin radar suna da yawa, kuma tsarin masana'antu yana da rikitarwa, don haka farashin ya fi tsada fiye da na'urar auna matakin ultrasonic, wanda ke iyakance iyakokin aikace-aikacensa zuwa wani matakin, musamman a wasu lokutan da ke da saurin tsada.
Yana da wuya a auna matsakaiciyar da ƙaramin ma'aunin dielectric: ga matsakaiciyar da ƙaramin ma'aunin dielectric, siginar da aka nuna ta raƙuman radar ba ta da ƙarfi, wanda zai iya shafar daidaiton ma'auni. Mita matakin ruwa na ultrasonic ba ta da saurin dielectric na matsakaiciyar, kuma ya fi dacewa don auna matsakaiciyar tare da manyan ko ƙananan canje-canje a cikin ma'aunin dielectric.
Akwai yankin makaho: na'urar auna matakin radar tana da wani yanki na makaho kusa da wurin farawa, yawanci santimita goma zuwa kimanin mita ɗaya, kuma ba za a iya auna matakin ruwa kusa da ƙasa ba. Yankin makaho na na'urar auna matakin ultrasonic ƙanƙanta ne, yawanci tsakanin santimita kaɗan zuwa santimita goma.
Rashin shigar sigina mara kyau: raƙuman radar ba za su iya shiga kayan haske masu ƙarfi kamar ƙarfe ba, idan kwantena ƙarfe ne da rufin ciki ko kuma rufin rufi, na iya shafar yaɗuwar raƙuman radar da kuma nuna su, buƙatar amfani da hanyar shigarwa ta musamman ko zaɓar samfurin ma'aunin matakin radar da ya dace. Raƙuman sauti na na'urar auna matakin ultrasonic na iya shiga wani kauri na kayan da ba na ƙarfe ba, kuma daidaitawar kayan kwantena da tsarinsu yana da kyau sosai.
