He aha te hiranga o te pūoko wiri ki te motuka? He aha tōna kaupapa matua?

Ko te pūoko wiri tētahi o ngā wāhanga matua o te hangarau whakamātautau. He iti te utu, he tino aro, he pumau, he pono hoki te mahi, ā, he whānui te whānuitanga o te kimi wiri. He whānui te whakamahinga i roto i ngā mara maha pēnei i te pūngao, te ahumahi matū, te rongoā, te motuka, te whakarewa, te hanga mīhini, te ahumahi hōia, te rangahau pūtaiao me te whakaako.

I roto i ngā pūnaha ine wiri katoa, ko te pūoko wiri te mea nui rawa atu. He mahi nui tāna i roto i te ine wiri. Nā te whakapai tonu o te taumata mōhiotanga me ngā whakaritenga pono teitei o ngā taputapu, ko te aroturukitanga tūnga ipurangi o te motuka taraiwa me te urupare wā-tūturu o ngā tohu tūranga me te tere ka noho hei paerewa. Kei te piki haere te whakamahinga o ngā āpitihanga motuka pēnei i ngā waehere, ngā pana tere nui, PT100, PTC, ngā pūoko wiri, me ētahi atu. He mea tino nui kia mārama ngā kaihanga taputapu ki ēnei āpitihanga me te mohio ki tā rātou whakaurunga ā-tinana ki te motuka.

Hei tauira, i roto i ētahi taputapu, me aroturuki te wiri o ētahi wāhanga. Me tāuta he pūoko i te wā tāutanga hei aroturuki i te wiri i ngā tere rerekē kia tutuki ai te kaupapa aroturuki me te tiaki tika kia whakaitihia ai te kino o ngā taputapu.

Mena kāore i te tino teitei te whakaritenga urupare auau, ka taea e koe te whakamahi i tētahi pūoko 4-20mA me te putanga tere, te kohikohi raraunga mā te PLC, me te aroturuki i te uara RMS tere. Mēnā rānei, whakamahia he taputapu whakaatu hei tohutoro aroturuki i te papaanga. Mena he teitei te whakaritenga urupare auau, ka taea e koe te whakamahi i tētahi pūoko 4-20mA me te putanga whakatere, te whakamahi rāneiACputanga tohu. Mā te PLC tere ake, mā te kāri hopu rānei, ka kohia ngā uara whakaterenga ka whakahohe i ngā mahi tiaki e whai ake nei i te wā tūturu.

E whakamahia whānuitia ana ngā pūoko wiri i roto i ngā ahumahi maha: pērā i te tukatuka whakarewa, te hanga sima, te ahumahi hanga pepa, te ahumahi moana, te keri me te keri pari, te whakaputa hiko hau, te kai me te inu, te ahumahi rongoā, te kawe tereina, te tango hinu me te hau, te ahumahi hiko me ētahi atu ahumahi.
