Pūnaha Whakahaere Pūhiko Pūnaha Temperature Sensor
Whakaahuatanga
Ka whakamahia e te pūoko pāmahana pūhiko he whare whakarewa konumohe ihu waea, ka taea te tiaki pai i te maramara NTC. I tetahi atu ringa, he tere te pāmahana o te kakano konumohe. Ko te tere tauhohenga waiariki o te NTC kaore e pa.
Ko te hoahoa o te tuwhera o mua o te anga konumohe me te diameter o te 4mm ka whakarite i te urupare waiariki o te NTC me te ngawari ki te whakauru.
Ma te whakamahi i te hiri karaehe radial na te mea ko te huānga whakamaarama o te pāmahana matua ka taea te mahi i roto i te taiao pāmahana teitei i tetahi taha. (mahi neke atu i te 150 nga nekehanga mo te wa roa), i tetahi atu taha, ka tahuna e te thermistor NTC te karaehe hiri te karaehe ki roto i te hanganga porowhita, e takai ana i te maramara thermistor NTC. Ko tona pono he teitei ake i tera o te hanganga kete o te hiri karaihe axial. Tuatoru, he kaha ake te kaha o te aatete miihini NTC mo te karaehe radial porowhita i hirihia i te axial glass hiri nga thermistors NTC. Ko te ahua tuawha, he iti ake te karaehe radial i hirihia NTC thermistor rahi (ko te radial glass hiritia NTC thermistor temperature sensor te rahi o te upoko he 1.3mm anake. Ko te axial glass hirihia NTC thermistor temperature sensor te rahi o te upoko he 6mm. Na ahakoa tenei hanganga kua hipokina ki te Ko te anga parahi o waho kaore e tino pa ana.
Ngā āhuatanga
He iti te rahi o te hua, he nui te ngaohiko aukati me te wa whakautu waiariki.
Te tere, te whanui o te pāmahana whakahaere, te pai o te ine ine ine, te roa o te mahi mahi me etahi atu.
Taupānga
Ka taea te whakamahi whanui i roto i nga putea hiko waka hiko hou, nga putea pākahiko, te kitenga pāmahana maha-ira ranei.
