He aha i whānuitia ai te whakamahinga o te Pt1000 i roto iTe Ine i te Werame ōna rerekētanga mai i te Pt500 me te Pt100
;
Kupu Whakataki
I te weraineI roto i ngā tono, he mea nui te mahi a ngā pūoko pāmahana ki te whakatau tika i te pāmahana, he mea nui mō te tatau i te whakawhiti wera me te whakapaunga pūngao. I roto i ngā momo pūoko pāmahana, he whānui te whakamahinga o ngā pūoko pāmahana ātete konukawata (RTD) nā te mea he tino tika, he pumau, he whānui hoki te whānuitanga o te pāmahana. Ko te Pt1000, te Pt500, me te Pt100 ngā momo RTD konukawata noa, ko te Pt1000 te mea e tino whiriwhiria ana i roto i ngā āhuatanga ine wera maha. Ka tūhuratia e tēnei tuhinga ngā take i muri i te rongonui o te Pt1000, ā, ka matapakihia ngā rerekētanga i waenga i te Pt1000, te Pt500, me te Pt100.
Ngā Take mō te Whakamahinga Whānui o te Pt1000 i roto i te Ine Wera
Te Tairongo Teitei Ake
Ko te ātete ingoa o Pt1000 he 1000 ohms i te 0 °C, ko te ātete ingoa o Pt100 he 100 ohms i te pāmahana kotahi, ā, ko te ātete ingoa o Pt500 he 500 ohms i te 0 °C. Ko te ātete ingoa teitei ake o Pt1000 ka hua ake he panoni nui ake i te ātete mō ia wae huringa pāmahana. Hei tauira, mō te rerekētanga pāmahana iti, he nui ake te huringa ātete o Pt1000 ki te whakaritea ki te Pt100 me te Pt500. Mā tēnei aro nui ake ka taea te ine i te pāmahana tika ake, he mea tino nui tēnei i roto ite ine i te werai ngā wāhi ka pā nui ngā rerekētanga pāmahana iti ki te tika o te tatau wera. I roto i ngā tono pēnei i te calorimetry tino tika, i ngā wāhi e tika ana kia kitea tika ngā huringa pāmahana iti hei tatau tika i te whakawhiti wera, ka whakaratohia e te aro nui o Pt1000 he painga motuhake.
Te Whakaiti i te Pānga o te Ātete Waea Mata
I roto i ngā whakatakotoranga ine wera mahi, he maha ngā wā ka honoa te pūoko pāmahana ki te taputapu ine mā roto i ngā waea arataki. Ka taea e te ātete o ēnei waea arataki te whakauru i ngā hapa ki te uara ātete ine o te RTD, ā, ka pā ki te tika o te ine pāmahana. Nā te mea he teitei te ātete ingoa o Pt1000, he iti ake te pānga o te ātete waea arataki ki te ine ātete whānui ki te Pt100 me te Pt500. Hei tauira, ki te mea he torutoru ohms te ātete waea arataki, ka nui ake te ōrau hapa i roto i te ātete ine o Pt100 (me te ātete ingoa o 100 ohms) ki te Pt1000 (me te ātete ingoa o 1000 ohms). Nā tēnei ka pai ake te Pt1000 mō ngā tono e hiahiatia ana he roa o ngā waea arataki, pērā i roto i ngā pūnaha whakawhiti wera ahumahi kei reira pea te pūoko pāmahana kei tawhiti atu i te rūma whakahaere.
Hototahi ki ngā Hikohiko Hou
Kua hangaia ngā taputapu ine hiko hou hei whakahaere i te whānuitanga o ngā tohu whakauru. Ko te Pt1000, me tōna ātete ingoa 1000 - ohm i te 0 °C, he pai te ōrite ki te aukati whakauru me ngā āheinga whakatikatika tohu o te maha o ngā pūnaha ine me te whakahaere o nāianei. He maha ngā wā ka arotauhia ēnei pūnaha kia mahi me ngā tohu e rite ana ki ngā āhuatanga ātete - pāmahana o te Pt1000. Hei tauira, he maha ngā kōwae ine pāmahana e hangai ana ki te microcontroller kua whakatikatikaina mō ngā pūoko Pt1000, e whakarato ana i ngā atanga ngāwari ki te whakamahi me ngā pānui pāmahana tika. Mā tēnei hototahi ka māmā ake te hoahoa me te whakatinanatanga o ngā pūnaha ine wera, ka whakaitihia te hiahia mō ngā tukanga whakawhiti tohu me te whakatikatika uaua.
Te Whakaritenga mō ngā Taupānga Tino Tika
Te ine i te weraI roto i ētahi mara, pērā i te rangahau pūtaiao, te hanga rongoā, me ngā tukanga ahumahi matatau, e hiahiatia ana he ine pāmahana tino tika. Ka taea e Pt1000 te whakatutuki i ēnei whakaritenga me tōna tino tika me te pumau. I roto i ngā whakamātautau pūtaiao e pā ana ki te thermodynamics, he mea nui te ine wera tika hei whakamana i ngā tauira ariā. Mā te hapa iti i roto i te ine pāmahana ka arahi pea ki ngā rerekētanga nui i roto i ngā hua tatau wera. Mā Pt1000, me tana mahi tino pai i roto i te ine pāmahana tika, ka whakarite kia pono ngā raraunga ine wera kua riro mai, ā, ka taea te tautoko i te rangahau pūtaiao hōhonu me ngā tukanga whakaputa ahumahi kounga teitei.
Ngā rerekētanga i waenga i te Pt1000, te Pt500, me te Pt100
Ngā Uara Ātete Ingoa
E ai ki te kōrero i mua ake nei, ko te rerekētanga tino kitea i waenga i a Pt1000, Pt500, me Pt100 ko ō rātou uara ātete ingoa i te 0 °C. Ko te ātete ingoa o Pt1000 he 1000 ohms, ko te Pt500 he 500 ohms, ā, ko te Pt100 he 100 ohms. Ka pāngia e ēnei uara ātete rerekē tō rātou aro me te pānga o te ātete waea mata e ai ki te whakaahuatanga i runga ake nei. Ko te kōwhiringa o te ātete ingoa ka whakawhirinaki ki ngā whakaritenga motuhake o tete ine i te werate tono, pērā i te tika o te ine e hiahiatia ana, te roa o ngā waea arataki, me te hototahi ki te pūnaha ine o nāianei.
Te Tairongo me te Tika
Ko te Pt1000 te mea tino aro ki te pāmahana i roto i ngā mea e toru, ā, muri iho ko te Pt500, kātahi ko te Pt100. E pā ana te aro ki te huringa o te ātete mō ia nekehanga Celsius o te huringa pāmahana. Ko te teitei ake o te ātete ingoa, ko te nui ake o te huringa o te ātete mō tētahi huringa pāmahana kua whakaritea, ka hua ake he aro nui ake. Mō te tika, ka taea e ngā momo RTD platinum e toru te whakatutuki i te tika taumata teitei ina whakatikatikaina tika. Heoi, nā te teitei ake o tōna aro, ka taea e te Pt1000 te whakarato i ngā inenga pāmahana tika ake i roto i ngā tono e tika ana kia whakatauhia tika ngā rerekētanga pāmahana iti. Hei tauira, i roto i te whakamātautau whai huatanga o te whakawhiti wera, i te mea he torutoru noa iho ngā nekehanga Celsius te rerekētanga pāmahana i waenga i ngā wai tomo me ngā wai putanga, ka taea e te Pt1000 te ine i ēnei rerekētanga iti kia tika ake i te Pt100.
Te utu
I te nuinga o te wā, he nui ake te utu o ngā pūoko Pt1000 i tō te Pt100 me te Pt500. Ko te take nui o tēnei, he nui ake te tika o te whakahaere i roto i te tukanga hanga o ngā pūoko Pt1000 kia eke ai ki te uara ātete teitei ake me ngā āhuatanga mahi teitei e pā ana. Ko te utu teitei ake pea he mea whakawhāiti i roto i ētahi tono tairongo utu. Heoi, i roto i ngā tono e tino nui ana te ine wera tino tika, pērā i roto i te umanga rererangi mō te whakahaere wera miihini, i roto rānei i ngā taputapu hauora teitei mō ngā tukanga e whakahaerehia ana te pāmahana, he maha ngā wā ka nui ake ngā painga mahi o te Pt1000 i te utu. I tetahi atu taha, he iti ake te utu o te Pt100, ā, he pai pea mō ngā tono kāore i te tino teitei te tika e hiahiatia ana, pērā i ētahi tono aroturuki pāmahana ahumahi taketake.
Ngā horopaki tono
Ko te Pt1000 te mea e whakamahia nuitia ana i roto i ngā tono e hiahiatia ana te ine wera tino tika, pērā i roto i ngā taiwhanga rangahau mō ngā whakamātautau ine karori, i roto i te umanga haurua-ira mō te whakahaere pāmahana i te wā e tukatuka ana i te wafer, me roto i ngā pūnaha HVAC teitei mō te ine i te whakapaunga pūngao tika. Ka taea te whakamahi i te Pt500 i roto i ētahi tono tika-waenga ina teitei ake ngā whakaritenga aro i ērā o te Pt100 engari kāore i te tino kaha pērā i ērā o te Pt1000. Ko te Pt100, me tōna utu iti ake me te tika tonu e whakaaetia ana mō ngā tono whānui maha, e whakamahia whānuitia ana i roto i te aroturuki pāmahana ahumahi, pērā i roto i te whakahaere pāmahana poiha, te ine pāmahana rūma ngāwari i roto i ngā whare, me ētahi aroturuki pāmahana miihini motuka taketake.
Whakamutunga
Hei whakamutunga, e whakamahia whānuitia ana a Pt1000 i roto i te werainenā te mea he tino aro nui, he iti ake te ātete o te waea mata, he hototahi ki ngā hikohiko hou, me te kaha ki te whakatutuki i ngā whakaritenga o ngā tono tino tika. Ko ngā rerekētanga i waenga i te Pt1000, Pt500, me te Pt100 e pā ana ki ngā uara ātete ingoa, te aro, te tika, te utu, me ngā horopaki tono e pai ai ia momo mō ngā hiahia ine wera rerekē. I te wā e whiriwhiri ana i te platinum RTD mō te tono ine wera, me āta whakaaro ngā kaihangarau me ngā kaihoahoa ki ēnei āhuatanga hei whiriwhiri i te pūoko tino tika hei whakarite i ngā hua ine wera tika me te pono.
