RTD pūoko

Kei te whakamahia whānuitia te kaha o konganuku ki te huri o ratou āhuatanga ōkiko raro i te mana o te pāmahana i roto i te whakatangitangi. Ko te kupu, hei tauira, whakamahi konukawata resistance ine pāmahana te taonga whakarewa ki te whakapiki ake i tona ātete hiko ki te whakanui ake i te pāmahana. Hei tauira, i te t = 0 ^C. konukawata he resistivity o 100 ohms.

Resistance ine - te mita mana, e whakawhiti ki te kaiwhakahaere i te parenga ia o nāianei tohu i waenganui i nga hoapā pūoko. tukanga i te pūmana te raraunga, me te e tuku ratou ki te pūnaha SCADA, te wahi e taea te kite kua te operator te āhua o te pāmahana o nāianei i roto i te tukanga ahumahi. whakamahia te ine pāmahana resistance te rite te matū me te hanga aunoa.

Ko te tino ohie hoahoa pūoko. Parahi resistance ine Kei toru hoapā, e rua o nei e katia ki tetahi ki tetahi, me te tuatoru - te katoa, te mea he ātete o 120 ohms. hono Ko te nuinga te pūnaha toru-waea, ahakoa i reira he okotahi. Me tiaki te taura i te pūrere ki te mana i te pokanoa tuatoru-rōpū. e kore kia whakatakotoria reira tahi me waea hiko, me te kia paruruhia.

ara iahiko Whakahaere Ko e whai ake: RTD - arai - te pūnaha mana aunoa. eke te pūrere te i runga i te taiepa, tukanga tīwae, whakamahia hoki pāmahana inenga i roto i ahunga mahi papua. Ko te mahi RTD he unpretentious me tika tika ona pānuitanga rerekē i te mōrahi tūturu o 0.7 nekehanga.

Mai te hoahoa o taua te pūrere iho, rite te ine pāmahana ātete, kua pā hāngai ki te wera whakawhiti i te reo ki te parenga, ka tangohia te tāutanga kei ki pūkete me te pūoko wāhi. Me kiriweti te taiepa, i te wāhi i homai o te auau rere reo kia whakanuia. Ko te hapa i roto i te ine e taea te whakaiti i te huringa i roto i te huru o te roa pūoko tokotoko ki te diameter TC. Atu i ka waiho atu, te pai ka hei te hua. Me tātai te hohonu rumaki me te huru o te reo whakawhiti wera ki te ruri. Hei tauira, i roto i ngā taiao tiketike-wera pērā i te mamaoa wai ranei kia nui reira 1.5 wa te roa kaha o te pūrere resistance ine.

"Thermowell" tuatahi whakaturia i roto i te tāutanga i roto i te kōwhiringa o te wahi. Tenei ahua o ringaringa paruru, te tikanga ki te whakahaere i disassembly o te pūrere, i roto i te kia e taea te whakakapi i te pūoko kahore hoki e mutu i te tukanga. Mai Ko te whānuitanga o te pāmahana inenga i roto i te whānuitanga o 200 ki te 600 degrees, kua hanga te ringaringa paruru i he kowiri tira. A, no te whakamahia i roto i te riri taiao waikawa taketake ranei Ōseni pani ki te hanganga polymer motuhake ātete ki te reo whanganga.

E hua Ātete ine pāmahana i roto i te whenua maha huri noa i te ao. Ko te tauira tino pai-mohiotia: te American "Ngā reo", Russian "Metran" me Pākehā "Endress Hauser". Ēnei whakaaro i te nui rawa o te tika. Ko ratou e kore anake e taea ki te tuku i te pāmahana taimau, engari ano ki te hanga inenga i te pāmahana tere te huri.
