He aha te mea he thermostat?
He maha ngā ingoa o ngā pūmana pāmahana, pērā i ngā pana whakahaere pāmahana, ngā parenga pāmahana me ngā pūmana pāmahana. E ai ki te mātāpono mahi, ka taea te wehewehe ki te momo pūmana peke, te pūmana wai, te pūmana pēhanga me te momo pūmana hiko. I roto i ngā taputapu whakahaere ahumahi hou, ko te pūmana mamati te momo e whakamahia whānuitia ana. E ai ki te hanganga, ka taea te wehewehe i te pūmana pāmahana ki te pūmana pāmahana whakauru me te pūmana pāmahana modular.
He aha ngā inemahana?
Ko te tinana ine pāmahana he wāhanga e huri ana i te tohu pāmahana hei tohu hiko, ā, he mea tāuta ki te wāhanga kimi o te mea e whakahaeretia ana hei aroturuki i tōna uara pāmahana. I roto i te mara o te whakahaere ahumahi, ko ngā inemahana e whakamahia whānuitia ana ko ngā takirua wera, ngā ātete wera, ngā whakamahana me ngā pūoko kore-pa. I roto i ēnei, ko ngā mea tuatahi e toru ko ngā inemahana pa.
1. Te honohono wera
Ko te kaupapa o te ine i te pāmahana mō ngā thermocouples e ahu mai ana i te pānga Seebeck (te pānga thermoelectric). Ina hanga e ngā konganuku e rua o ngā rauemi rerekē (ko te nuinga he kawe hiko, he semiconductors rānei, pērā i te platinum-rhodium, te nickel-chromium-nickel-silicon me ētahi atu rauemi kua honoa) he porowhita kati, ā, ka whakamahia he pāmahana rerekē ki ō rātou pito hono e rua, ka puta he kaha hiko i waenga i ngā konganuku e rua. Ka kiia tēnei porowhita he "thermocouple," ko ngā konganuku e rua he "thermal electrode," ā, ko te kaha hiko e puta mai ana ka kiia he "thermoelectric motive force." Ko ngā thermocouples e tohuhia ana e tō rātou whānuitanga pāmahana ine whānui, te urupare wera tere, me te ātete wiri kaha.
2. Ātete wera
Ko te ātete wera he wāhanga e huri ana i te tohu pāmahana hei tohu hiko, ā, ko tōna kaupapa mahi e ahu mai ana i ngā āhuatanga o te ātete whakarewa e rerekē ana i te pāmahana. Ina koa, ka whakamahia e ngā ātete wera tēnei āhuatanga o te whakarewa hei ine i te pāmahana.
I roto i te whakahaere ahumahi, ko ngā momo ātete wera e whakamahia whānuitia ana ko te konukawata, te parahi me te nikara. I roto i ēnei, ko te ātete konukawata te mea tino noa. Ko ngā āhuatanga o te ātete wera ko te pai o te raina pāmahana, te mahi pumau me te tino tika i te mara o te pāmahana noa. Nō reira, i roto i te taiao tono o te pāmahana ngawari, te kore wiri me ngā whakaritenga tino tika, ko te whakamahinga o te ātete konukawata te mea e pai ake ana.
3. Teimita
Ko te thermistor he wāhanga e huri ana i te tohu pāmahana hei tohu hiko, ā, ko tōna kaupapa mahi e ahu mai ana i ngā āhuatanga o te ātete o te semiconductor e rerekē ana i te pāmahana. Ina koa, ka whakamahia e ngā thermistor tēnei āhuatanga o ngā semiconductor hei ine i te pāmahana. Ki te whakatauritea ki te ātete wera, ka tino rerekē te ātete o te thermistor i te huringa o te pāmahana, nō reira he whaiti te whānuitanga ine pāmahana (-50~350℃).
Ka wehea ngā whakamahana ki ngā whakamahana NTC me ngā whakamahana PTC. He tauwehenga pāmahana kino tō ngā whakamahana NTC, ā, ka heke te uara ātete i te pikinga o te pāmahana. He tauwehenga pāmahana pai tō te whakamahana PTC, ā, ka piki ake tōna uara ātete i te pikinga o te pāmahana. Nā ōna āhuatanga ātete pāmahana ahurei, he whānuitia ngā tono a te whakamahana ki te kimi pāmahana, te whakahaere aunoa, ngā taputapu hiko me ētahi atu mara.
