He wāhanga nui te ine pāmahana o te whakahaere tukanga puta noa i ngā momo ahumahi whānui pēnei i te hanga matū, te hinu me te hau, ngā rongoā, me te hanga kai. He taputapu nui te pūoko pāmahana e ine tika ana i te pūngao wera me te whakamaori i te nekehanga pāmahana ki ngā tohu hiko hei whakatutuki i te aroturukitanga tonu me te kohikohi raraunga mō te mahi a te tukanga i roto i te whānuitanga pāmahana kua tautuhia. E ai ki te kōrero i roto i teKa taea e tātou te whakakapi i te RTD ki te Thermocouple?Ko ētahi o ngā huānga pūoko pāmahana noa ko te RTD me te TR, he tino pai rāua i ngā whānuitanga ine rerekē, ā, ka whakaputa motuhake i te tohu ohm/mV.
Ahakoa kua roa te pūoko pāmahana e mahi ana hei taputapu matua mō te hopu raraunga wera takitahi, ka taea te whakauru ki ngā pūnaha tuku i roto i ngā tono whakahaere tukanga. Ko te tuku pāmahana he taputapu takawaenga e hono ana ki te pūoko RTD, ki te pūoko thermocouple rānei, ka whakanui me te whakarite i te tohu pūoko ki te tohu hiko paerewa, kātahi ka tukuna ki ngā hiko whiwhi. Ko ngā tohu whakarite e pānuihia ana mō te whakamahi e te pūnaha whakahaere o muri pēnei i te PLC, DCS rānei he whakawhitiwhitinga anaro 4-20mA me te whakawhitiwhitinga mamati Hart, Modbus rānei.
Ngā painga o te whakamahi i te tuku pāmahana
Ahakoa he mea nui tonu ngā pūoko pāmahana mō te kohikohi raraunga, he maha ngā whakapainga ka whakapai ake i te whai huatanga o ngā tuku raraunga:
Te whakapakari i te pono o te tohu:He ngoikore te tohu ngaohiko iti i roto i te ara iahiko e whakaputaina ana e te pūoko pāmahana anake, ā, he ngāwari ki te haruru hiko me te pokanoa me te hekenga o te tohu i tawhiti. Ki te whakataurite, he kaha ake te tohu 4-20mA e whakahaeretia ana e te tuku, ā, he āwhina i te ātete ki te pokanoa hikohiko. Mā te whakarārangi me te utu mō te putanga mata o te pūoko ka tika ake, ka pono ake te tuku raraunga ki te taputapu whakahaere.
Hototahi me te whai wāhitanga:He hototahi te waeine tuku pāmahana ki ngā pūoko RTD me ngā pūoko thermocouple. Ka whakaaetia hoki te whakamahi i ngā huānga pūoko maha. Nā te maha o ngā āhuatanga ka taea te whakamahi whānui i te pūoko ki ngā momo ine pāmahana katoa me ngā whakaritenga whānuitanga me te rahinga pūoko rerekē. Ka taea te whakanoho i te tohu kei runga i te pouaka pito, kia māmā ai te pānui me te whirihoranga ā-rohe.
Te whakaurunga pūnaha kua whakapaitia:Mā te putanga tuku kua whakaritea ka taea te whakauru pai ki ngā pūnaha whakahaere pēnei i te kaiwhakahaere arorau hōtaka (PLC) me te pūnaha whakahaere tohatoha (DCS). Ka taea e te whakawhitiwhiti mamati te aroturuki raraunga mamao me te whakarerekētanga tawhā, ka whakaitihia te hiahia mō te urunga ā-tinana ki ngā wāhi morearea, uaua rānei ki te tae atu. Ka māmā ake te whakatikatika anō i te mara mā te atanga mamati, ā, ka whakaitihia te wā kore mahi ki te whakaritea ki te mahi ā-ringa.
