I ngā marama makariri o te takurua, he maha ngā wā ka pāngia ngā kaipupuri waka hiko katoa e te wero: te whakamahana i roto i te motuka. Kāore i rite ki ngā waka penehīni, e taea ai te whakamahi i te wera para mai i te miihini hei whakamahana i te kāpini, me whakamahi ngā waka hiko katoa i ētahi atu taputapu whakamahana. Kāore e whai hua ngā tikanga whakamahana tuku iho, he nui rawa rānei te pūngao e pau ana, ā, ka pā nui ki te tawhiti o te waka. Nō reira, he otinga kei reira hei whakarato i te whakamahana tere me te whai hua o te pūngao? Kei roto i te whakautungā whakamahana wai PTC ngaohiko teitei.
Ko te PTC he whakarāpopototanga mō te Positive Temperature Coefficient (PTC), arā, ko te thermistor tau pāmahana pai (PTC).Ngā whakamahana whakamatao PTC ngaohiko teiteiwhakamahi i ngā āhuatanga o ngā whakamahana PTC, e mahi ana i te ngaohiko teitei hei huri i te pūngao hiko ki te wera, ā, mā reira ka whakamahana i te wai whakamatao. Ko te mātāpono whakahaere oNgā whakamahana wai PTCe hangai ana ki te meka ka piki ake te ātete o ngā whakamahana PTC i te pikinga o te pāmahana. Ina rere te iahiko i roto i te whakamahana PTC, ka wera ake. I te pikinga o te pāmahana, ka piki ake te ātete, ā, ka heke te iahiko, ā, ka tutuki te whakawhāititanga pāmahana aunoa, ka whakarite i te haumaru me te whai hua o te pūngao.
I roto i ngā waka hiko pūngao hou, ka tohatohahia te putanga ngaohiko teitei mai i te pākahiko o te waka ki te whakamahana PTC. Ka rere te iahiko mā te huānga whakamahana PTC, ka tere te whakamahana, ā, ka wera anō hoki te wai whakamatao e rere ana i roto. Kātahi ka haria tēnei wai whakamatao wera mā te tātari wai me te papu ki te tāke whakamahana o te waka. Kātahi ka mahi te whakamahana, ka pupuhi i te wera mai i te tāke whakamahana ki roto i te kāpini, ka tere te whakanui ake i te pāmahana o roto. Ka taea hoki te whakamahi i ētahi o te wai whakamatao hei whakamahana i te kete pākahiko, kia pai ai te mahi ahakoa i roto i ngā taiao pāmahana iti.
