He whānuitia te whakamahinga o ngā whakamahana i roto i ngā tono tirotiro me te whakahaere pāmahana puta noa i ngā momo ahumahi. I roto i ngā momo rerekē ongā whakamahana, ko te PTC (Positive Temperature Coefficient) me te PT100 ngā momo e rua e whakamahia whānuitia ana. E whakamahia ana ngā momo whakamahana e rua mō te ine i te pāmahana, engari he rerekē ngā āhuatanga me ngā whakamahinga. He mea nui te mārama ki ngā rerekētanga i waenga i ngā whakamahana PTC me PT100 hei whiriwhiri i te pūoko tika mō ō hiahia pūmana pāmahana.
Te whakamahana PTC:
He ātete tairongo-pāmahana ngā whakamahana PTC me te tauwehenga pāmahana pai, ko te tikanga ka piki ake tō rātou ātete i te pikinga o te pāmahana. He mea hanga ēnei whakamahana ki ngā rauemi uku pērā i te barium titanate, ā, ka rerekē nui tō rātou ātete i ngā huringa o te pāmahana. He mea whakamahi noa ngā whakamahana PTC i roto i ngā tono e hiahia ana ki te tiaki i te pāmahana nui, te whakahaere-ā-roto, me te whakawhāiti i te au.
Ko tētahi o ngā āhuatanga matua o ngā whakamahana PTC ko ō rātou āhuatanga whakahaere-ake. I te pikinga o te pāmahana, ka piki ake te ātete o te whakamahana PTC, ka heke te iahiko. Nā tēnei whanonga whakahaere-ake e pai ai ngā whakamahana PTC mō ngā tono pēnei i te tiaki motuka, ngā wāhanga whakamahana, me te tiaki iahiko nui i roto i ngā ara iahiko hiko.
Pūoko wera takai:
Ka whakamahia ngā pūoko wera takai i roto i ngā taputapu hiko hei aroturuki i te pāmahana o ngā takai i roto i ngā motuka, ngā whakawhiti hiko me ētahi atu taputapu hiko. He mea nui ēnei pūoko hei ārai i te wera nui me te whakarite kia haumaru te mahi a ngā taputapu. Ko ngā pūoko wera takai he tikanga whakamahi i ngā whakamahana PTC hei wāhanga pūoko pāmahana nā te mea he āhuatanga whakarerekē-ā-unoa ō rātou, ā, he tino tairongo ki ngā huringa pāmahana.
Te whakamahana PT100:
He taputapu kite pāmahana ātete (RTD) te PT100 e whakamahi ana i te konukawata hei wāhanga ine. Kāore i rite ki ngā whakamahana PTC, ka piki haere te ātete o ngā whakamahana PT100 i runga i te pāmahana, e whai ana i te whanaungatanga ātete-pāmahana paerewa i tautuhia e te International Electrotechnical Commission (IEC). E mōhiotia ana ngā whakamahana PT100 mō te tino tika, te pumau me te whānuitanga o te ine pāmahana, e pai ai mō ngā tono ine pāmahana tino tika.
Ko te ātete o te thermistor PT100 he 100 ohms i te 0°C, ā, ka piki ake mā te 0.385 ohms mō ia nekehanga pikinga pāmahana. Mā tēnei hononga rārangi i waenga i te ātete me te pāmahana ka taea te ine tika me te pono i te pāmahana puta noa i te whānuitanga o te pāmahana.
Te rerekētanga i waenga i te PTC me te PT100:
Ko te rerekētanga matua i waenga i ngā whakamahana PTC me PT100 ko ō rātou āhuatanga ātete-pāmahana. He hononga ātete-pāmahana kore-raina kei ngā whakamahana PTC me te tauwehenga pāmahana pai, ko ngā whakamahana PT100 ia he hononga ātete-pāmahana raina me te tauwehenga pāmahana tata-kore.
Ko tētahi atu rerekētanga nui ko ngā rauemi i whakamahia i roto i tōna hanganga. Ko ngā whakamahana PTC he mea hanga i ngā rauemi uku, ko ngā whakamahana PT100 ia e whakamahi ana i te konukawata hei wāhanga pūoko. Ko te whakamahinga o te konukawata i roto i ngā whakamahana PT100 ka whai wāhi ki te tino tika me te pumau, inā koa i roto i ngā taiao ahumahi me ngā taiao taiwhanga uaua.
tono:
Ka taea te whakamahi i ngā whakamahana PTC hei tiaki i te wera nui, i ngā waeine whakamahana whakahaere-ake, i ngā ara iahiko whakawhāiti au me te tiaki i te motuka. Nā te whanonga whakahaere-ake e pai ai mō ngā tono e tino hiahiatia ana te whakahaere me te tiaki i te pāmahana.
Ko ngā whakamahana PT100, i tētahi atu taha, e whakamahia whānuitia ana i roto i ngā taiao ahumahi me ngā taiwhanga mō te ine tika i te pāmahana. E whakamahia whānuitia ana ēnei i roto i ngā pūnaha aroturuki pāmahana, ngā rūma taiao, ngā pūnaha HVAC, me ngā tono rangahau pūtaiao e tino hiahiatia ana te ine pāmahana tika me te pumau.
Hei whakarāpopototanga, ahakoa e whakamahia ana ngā whakamahana PTC me PT100 mō te ine pāmahana, he rerekē ngā āhuatanga me ngā whakamahinga. E mōhiotia ana ngā whakamahana PTC mō ā rātou whanonga whakahaere-ake, ā, e whakamahia whānuitia ana i roto i ngā tono e hiahia ana ki te tiaki i te pāmahana nui me te whakawhāiti i te au. I tētahi atu taha, he tino tika, he pumau hoki ngā whakamahana PT100, e pai ai mō ngā ine pāmahana tika i roto i ngā taiao ahumahi me te taiwhanga. He mea nui te mārama ki ngā rerekētanga i waenga i ēnei whakamahana ki te whiriwhiri i te pūoko tika mō ō hiahia ine pāmahana.
