Isi ojiji na kpachara anya nke NTC thermistor

NTC na-anọchi anya "Ngative Temperature Coefficient". NTC thermistors bụ ndị na-emegide ya na ọnụọgụ okpomọkụ na-adịghị mma, nke pụtara na nguzogide na-ebelata na okpomọkụ na-abawanye. Ọ bụ manganese, cobalt, nickel, ọla kọpa na ndị ọzọ metal oxides dị ka isi ihe site seramiiki usoro.

Akpachara anya maka iji NTC thermistor
1. Lezienụ anya na okpomọkụ na-arụ ọrụ nke thermistor NTC.
Ejila thermistor NTC na-abụghị oke okpomọkụ na-arụ ọrụ. Ọnọdụ okpomọkụ nke usoro φ5, φ7, φ9, na φ11 bụ -40 ~ + 150 ℃; okpomọkụ na-arụ ọrụ nke φ13, φ15, na φ20 usoro bụ -40 ~ + 200 ℃.
2. Biko mara na NTC thermistors kwesịrị iji n'okpuru ọnọdụ ike kwadoro.
Ike kachasị nke nkọwapụta ọ bụla bụ: φ5-0.7W, φ7-1.2W, φ9-1.9W, φ11-2.3W, φ13-3W, φ15-3.5W, φ20-4W
3. Akpachara anya maka iji na oke okpomọkụ na oke iru mmiri gburugburu.
Ọ bụrụ na ọ dị mkpa ka a na-eji thermistor NTC mee ihe na ọnọdụ okpomọkụ dị elu na oke iru mmiri dị elu, a ga-eji ụdị okpomọkụ dị n'ọbọ ahụ mee ihe na akụkụ nke mechiri emechi nke mkpuchi mkpuchi ga-ekpuchi ya na gburugburu ebe obibi (mmiri, mmiri mmiri), na oghere oghere nke n'ọbọ ahụ. agaghị adị na kọntaktị ozugbo na mmiri na uzuoku.
