Inzwa yokushisa engu-PT100/PT1000

Ngokuthuthuka okuqhubekayo kokuzenzakalelayo kwezimboni, inzwa yokushisa, njengento ebalulekile yokulawula izimboni, isetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni. Inzwa yokushisa ye-PT100, njengenzwa evamile yokushisa, inekhono elinembile lokulinganisa izinga lokushisa nokusebenza okuzinzile, futhi ibilokhu ikhathazekile futhi isetshenziswa kabanzi.

Imingcele eyinhloko yeinzwa yokushisa PT100ikakhulukazi zihlanganisa izici ezilandelayo:

Ububanzi besicelo:

Izinzwa zokushisa ze-PT100 zisetshenziswa kabanzi ezinhlelweni zokulawula ezishintshayo zezimboni, amathuluzi aselabhorethri, imishini yezokwelapha, ukucubungula ukudla, amakhemikhali nezinye izinkambu ukukala izinga lokushisa loketshezi, amagesi kanye nezinto eziqinile.

Linearity:

Umugqa we-PT100 uvamise ukuba ±0.1% noma ngaphezulu. I-Linearity imelela ubuhlobo bomugqa phakathi kwezinga lokushisa nokumelana, okungukuthi, izinga lapho inani lokumelana lishintsha khona nezinga lokushisa. Umugqa ophezulu usho ukuthi ubudlelwano phakathi kwezinga lokushisa nokumelana bukhulu kakhulu.

Ukumelana okulinganiselwe:

Ukumelana okulinganiselwe kwe-PT100 yi-100 ohms, okungukuthi, ku-0 degrees Celsius, ukumelana kwayo yi-100 ohms.

Ibanga lokushisa:

IInzwa yokushisa ye-PT100 iyinzwa yokushisa esekwe kwiplatinamu ejwayele ukukala ukusuka ku-200°C kuya ku-+600°C. Kodwa-ke, ezinye izimo zingenza futhi ububanzi bawo bokulinganisa bufike ku -200 ℃ ~ +850 ℃. Isebenzisa izici eziqondile zokumelana neplatinamu ukuze kufinyelelwe ukukalwa kwezinga lokushisa ngokunemba okuphezulu nokuzinza.

Ukunemba komkhiqizo:

Ukunemba kwe-PT100 kuvamise ukuba ±0.1 degrees Celsius noma ngaphezulu. Lokhu kusho ukuthi inzwa iyakwazi ukukala izinga lokushisa ngokunembile futhi inikeze ukufunda okunembile phakathi kwebanga elithile.

Inani elivumelekile lokuchezuka:

Inani elivumelekile lokuchezuka le-PT100 liyahlukahluka kuye ngeleveli yokunemba. Ukuchezuka okuvunyelwe kokunemba kwekilasi A ngu-±(0.15+0.002│t│), kuyilapho ukuchezuka okuvunyelwe kokunemba Kwekilasi B kungu-±(0.30+0.005│t│). Lapho t kuyizinga lokushisa le-Celsius.

Isikhathi sokuphendula:

Isikhathi sokuphendula se-PT100 sivamise ukuba ama-milliseconds ambalwa ukuya kumashumi ama-milliseconds. Lesi yisikhathi esithatha inzwa ukuthi ishintshe ukusuka ekushintsheni kwezinga lokushisa ukuya ekushintsheni kwesignali kagesi ephumayo. Isikhathi sokuphendula esifushane sisho ukuthi inzwa iyakwazi ukuphendula ngokushesha ezinguqukweni zezinga lokushisa.

Ubude nobubanzi:

Ubude nobubanzi be-PT100 kungakhethwa ngokuya ngezidingo ezithile zohlelo lokusebenza. Ubude obujwayelekile buyimitha elingu-1, amamitha angu-2 noma ngaphezulu, futhi ububanzi buvamise ukuba ngu-1.5mm kuya ku-5mm.

Isignali yokuphumayo:

Isignali yokuphuma kwe-PT100 ngokuvamile iyinani lokumelana, elingaguqulwa libe yi-voltage evamile noma isignali yamanje ngebhuloho noma isiguquli.

Inzuzo yomkhiqizo:

Inzwa yokushisa ye-PT100 inezinzuzo zokunemba okuphezulu, ukuzinza okuhle, ikhono eliqinile lokulwa nokuphazamiseka nempilo ende yesevisi. Ezindaweni zezimboni, izinzwa zokushisa ze-PT100 zisebenza ngokuzinzile nangokunembile, zivumelana nezimo zokusebenza ezinzima.

Izici zomkhiqizo:

Inzwa yokushisa ye-PT100 inezici zokuphendula okusheshayo, ukuzwela okuphezulu, isakhiwo esilula nokufakwa kalula. Isakhiwo sawo esihlangene, usayizi omncane, ofanele ukufakwa kwendawo encane ehlukahlukene.

Ifomu lephakheji ye-temperature probe:

Kuyaqapheleka ukuthi kungase kube khona umehluko ku-PT100 ekhiqizwa abakhiqizi abahlukene, ngakho-ke qaphela imingcele ethile yobuchwepheshe ehlinzekwa abakhiqizi lapho ukhetha futhi usebenzisa. I-Weilian Fenran Sensor Technology Co., Ltd. ingumkhiqizi ochwepheshe wenzwa yokushisa ye-PT100, wamukelekile ukubonisana nokubambisana.

Ngokufigqiwe:

Njengohlobo lokunemba okuphezulu kanye nenzwa yokushisa yokuzinza okuhle, inzwa yokushisa ye-PT100 inethuba elibanzi lesicelo ohlelweni lokulawula okuzenzakalelayo kwezimboni, ithuluzi laselabhorethri, imishini yezokwelapha neminye imikhakha. Izici zayo zokuphendula okusheshayo, ukunemba okuphezulu nokuzinza okuhle kwenza kube yingxenye ebalulekile emkhakheni wokulinganisa izinga lokushisa kwezimboni. Kwethenjwa ukuthi ukwethulwa kwaleli phepha kungasiza abafundi baqonde kangcono izici nobubanzi bokusetshenziswa kwenzwa yezinga lokushisa le-PT100, futhi kunikeze ireferensi nesiqondiso sokusetshenziswa kwayo okungokoqobo.
