Ungaqinisekisa Kanjani Izinga Lokushisa Elinembile Nomswakama Emazingeni Okushisa Aphansi Agcwalisiwe?

Ukulinganisa izinga lokushisa kanye nomswakama ezindaweni ezinezinga lokushisa eliphansi kubalulekile ezinhlelweni eziningi, njengokuqapha isimo sezulu, ukugcinwa kanye nokuthuthwa kwezimpahla ezizwela ukushisa, nezinqubo zezimboni. Izinga lokushisa elinembile kanye nezilinganiso zomswakama zibalulekile kulezi zinhlelo zokusebenza, njengoba ukuchezuka okuncane kungase kubangele imiphumela ebalulekile, njengokonakala komkhiqizo, ukwehluleka kwezisetshenziswa, kanye nezingozi zokuphepha.

Ukuqinisekisa ukulinganiswa okunembile kwezinga lokushisa nomswakama ezindaweni ezinezinga lokushisa eliphansi, kuyadingeka ukukhetha izinga lokushisa elilungile kanye nenzwa yomswakama futhi uyisebenzise ngendlela efanele. Lesi sihloko sizonikeza ukubuka konke kwezinto ezithonya ukunemba kokulinganisa izinga lokushisa nomswakama kanye namathiphu okuqinisekisa ukukalwa okunembile kwezinga lokushisa nokuswakama ezindaweni ezinezinga lokushisa eliphansi.

Ngokuvamile, siyahlola5 Izintoezithonya izinga lokushisa nokuswakama ngokunemba ngendlela elandelayo:

Uhlobo lwenzwa:Izinzwa ezihlukene zezinga lokushisa kanye nomswakamo zinamazinga ahlukene okunemba. Isibonelo, ama-thermistors anokunemba okuphansi uma kuqhathaniswa nama-thermocouples nama-RTD. Ngokufanayo, izinzwa ze-capacitive humidity zinembe kakhulu kunezinzwa zokuswakama eziqinile. Uma ukhetha inzwa yokushisa nomswakama, kubalulekile ukucabangela ukunemba okudingekayo bese ukhetha uhlobo lwenzwa ngokufanele.

Indawo yenzwa:Indawo yenzwa yokushisa nomswakama nayo ithinta ukunemba kwayo. Inzwa kufanele ibekwe endaweni emele indawo yemvelo ehloselwe ukuyikala. Kubalulekile ukugwema ukubeka inzwa elangeni eliqondile noma eduze nemithombo yokushisa noma umswakama ongathinta ukufundwa kwayo.

Ukulinganisa:Izinga lokushisa elivamile kanye nokulinganisa kwenzwa yomswakama kubalulekile ekufundeni okunembile. Inzwa kufanele ilinganiswe ngokulandela imiyalelo yomkhiqizi futhi ngezikhathi ezithile, njengaminyaka yonke noma kabili ngonyaka.

Izici Zemvelo:Izici zemvelo ezifana nokuguquguquka kwezinga lokushisa nokuswakama, uthuli, nokujiya kungathinta ukunemba kwezinzwa zezinga lokushisa nokuswakama. Kubalulekile ukugcina inzwa ihlanzekile futhi uyivikele ezicini zemvelo ezithinta ukunemba kwayo.

Isimo Sesiginali:Isignali yenzwa yokushisa neyomswakama kufanele ibekwe kahle ngaphambi kokuthi idluliselwe kusilori sedatha noma idivayisi yokubonisa. Lokhu kuhlanganisa ukuhlunga nokukhulisa isignali ukuze kuqinisekiswe ukuthi ayinamsindo futhi ine-amplitude eyanele.

Bese Futhi Nazi5 Amathiphukanye neseluleko sokuqinisekisa izilinganiso ezinembile zezinga lokushisa nokuswakama ezindaweni ezinezinga lokushisa eliphansi:

1. Sebenzisa inzwa yezinga lokushisa nokuswakama ngokunemba okuphezulu:Izinzwa ezinembe kakhulu zibalulekile ukuze kuqinisekiswe izinga lokushisa elinembile kanye nomswakama endaweni enezinga lokushisa eliphansi. Cabangela ukusebenzisa izinzwa ezinezincazelo ezinembile ezingu-±0.5°C kumazinga okushisa kanye no-±2% womswakama.

2. Linganisa inzwa njalo:Ukulinganiswa okuvamile kwezinga lokushisa kanye nenzwa yomswakama kubalulekile ukuze kuqinisekiswe ukufundwa okunembile. Inzwa kufanele ilinganiswe ngokulandela imiyalelo yomkhiqizi futhi ngezikhathi ezithile, njengaminyaka yonke noma kabili ngonyaka.

3. Beka kahle inzwa:Indawo yenzwa yezinga lokushisa nokuswakama ibalulekile ekulinganisweni okunembile. Inzwa kufanele ibekwe endaweni emele indawo yemvelo ehloselwe ukuyikala. Gwema ukubeka inzwa elangeni eliqondile noma eduze nemithombo yokushisa noma umswakama ongathinta ukufundwa kwayo.

4. Vikela inzwa ezintweni zemvelo:Izici zemvelo ezifana nokuguquguquka kwezinga lokushisa nokuswakama, uthuli, nokujiya kungathinta ukunemba kwezinzwa zezinga lokushisa nokuswakama. Kubalulekile ukugcina inzwa ihlanzekile futhi uyivikele ezicini zemvelo ezithinta ukunemba kwayo.

5. Sebenzisa isignali conditioning:Isignali evela kuzinga lokushisa kanye nenzwa yomswakama kufanele ibekwe kahle ngaphambi kokuba idluliselwe kusilori sedatha noma idivayisi yokubonisa. Lokhu kuhlanganisa ukuhlunga nokukhulisa isignali ukuze kuqinisekiswe ukuthi ayinamsindo futhi ine-amplitude eyanele.

Ukuqinisekisa ukukalwa okunembile kwezinga lokushisa nomswakama ezindaweni eziphansi lokushisa kubalulekile ezinhlelweni eziningi. Ngokukhetha izinga lokushisa elilungile nenzwa yomswakama, ukuyilinganisa njalo, nokuyivikela kukho

izici zemvelo, ungaqinisekisa ukuthi uthola ukufundwa okunembile. Kubalulekile futhi ukubeka inzwa endaweni emele indawo elinganiswayo kanye nokubeka kahle isignali esuka kunzwa ngaphambi kokuyidlulisela kusilogu sedatha noma idivayisi yokubonisa.

ngakho-ke uma ulandela lawa macebiso, ungasiza ukuqinisekisa ukuthi izinga lokushisa lakho kanye nezilinganiso zomswakama zinembile, ezingakusiza ugweme izinkinga ezingaba khona njengokonakala komkhiqizo, ukwehluleka kwemishini, kanye nezingozi zokuphepha. Ukwengeza, ngokusebenzisa izilinganiso ezinembile zokushisa nomswakama, ungakwazi ukuthuthukisa izinqubo zakho zezimboni, uthuthukise imikhiqizo namasevisi akho, futhi wandise ukusebenza kahle kwakho konke kanye nokuncintisana.

Izidakamizwa kanye nemithi yokugoma kubalulekile ekwelapheni izifo nokugcina impilo. Ivimbela ukubola kwezinto eziphilayo kanye ne-metamorphic yezinto eziphilayo. Ukuze kuphole amaseli, izicubu, noma ezinye izakhiwo zebhayoloji emazingeni okushisa aphansi kakhulu ukuze kugcinwe ukwakheka nokusebenza kwazo. Imithi nemithi yokugoma izobeka endaweni -60℃ noma -80℃.Izilogu zedatha yezinga lokushisa nomswakamanoma ti-emperature kanye ne-humidity transmitterkuyisinqumo esihle sokuqapha izinga lokushisa nomswakama endlini yesiqandisi ukuvimbela ukuguquguquka kwezinombolo kanye nokuqinisekisa indawo ehlala isiqandisi.

Ngezicelo ezinzima ze-cryogenic embonini yokugoma nezimboni zemithi, izinga lokushisa lika-Hengko nezinzwa zomswakama zinikeza izilinganiso ezinembile emazingeni okushisa aphansi. Angeke isetshenziselwe kuphela ukukala izindawo zokugcina izimpahla eziqandisiwe, kodwa futhi inezicelo ezihambisanayo zomkhiqizo zokuthutha ngamaketanga abandayo. Isibonelo, ekuthuthweni kwamaketanga abandayo, izinga lokushisa le-Constant HENGKO nerekhoda yomswakama lisetshenziselwa ukurekhoda nokuqapha yonke inqubo yokushisa nomswakama, ukuze kugwenywe "ukuphuka kweketango".

HENGKO RHT uchungechungeizinga lokushisa kanye nomswakama probeisebenza ukusuka ku -40 ° C (-104°F) kuya ku-125 ° C (257 °F) futhi ingasetshenziselwa ukuqapha izinga lokushisa eliphansi ezinhlelweni ze-cryogenic. I-probe yezinga lokushisa kanye nomswakama ingafakwa ngqo emkhunjini wokupholisa ngekhebula futhi idluliselwe ku-isidlulisi sokushisa nomswakamangokusebenzisa isignali yokuphuma kwe-I2C. Amanani alinganisiwe angahlanganiswa kalula ohlelweni lokulawula izinga lokushisa kanye nomswakama ukuze kuqinisekiswe ukugcinwa okunembile kwezinga lokushisa elidingekayo kanye nomswakama.

  Ngaphandle kwamazinga okushisa aphansi, uchungechunge lwezinzwa ze-HENGKO lokushisa nomswakama lufanelekile ukuqapha nokulawula izinqubo ezihlukahlukene zezimboni, ezifana nemboni yokudla, amakamelo ahlanzekile noma isimo sezulu kanye nama-laboratories.I-stainless steel probe housing iqinile kakhulu futhi ifanele udonga. noma ukufakwa kwamapayipi. I-probe yesilawuli kude inikeza ukuguquguquka okwengeziwe ekubekweni kwenzwa nasekufakeni.

Sengiphetha, ukuqinisekisa izinga lokushisa elinembile nomswakama endaweni yokushisa ephansi kudinga ukucatshangelwa ngokucophelela kohlobo lwenzwa esetshenziswayo, indawo yayo, nokuthi ivikelwa kanjani ezintweni zemvelo. Ngokunaka kakhulu lezi zici, ungaqinisekisa ukuthi izinga lokushisa lakho kanye nezilinganiso zomswakama zinembile futhi zithembekile, okubalulekile ezinhlelweni eziningi zokusebenza.

Ingabe uyazabalaza ukugcina izinga lokushisa elinembile nokufundwa komswakamo ezindaweni ezinezinga lokushisa eliphansi?
