Basa re thermistor

1. Thermistor anopesana yakagadzirwa nezvinhu zvakakosha, uye kukosha kwaro kupokana kunochinja nekushisa. Zvinoenderana neyakasiyana coefficient yekupesana shanduko, vanomisikidza vakakamurwa kuita mapoka maviri:

Imwe mhando inonzi yakanaka tembiricha coefficient Thermistor (PTC), iyo kukosha kweanodzivisa kunowedzera nekushisa;

Imwe mhando inonzi yakaipa tembiricha yekushatisa yedhisheni yeTermistor (NTC), iyo kukosha kwekudzidzira kunoderera nekuwedzera kupisa.

2. Thermistor inoshanda nheyo

1) Tembiricha yekudziya coefficient thermistor (PTC)

PTC inowanzogadzirwa neyebhari titanate sechinhu chikuru, uye hushoma hwezvinhu zvisingawanzo kuwedzerwa kuTitania reBarium, uye inogadzirwa nekudziya kwakanyanya kuchiviga. Barium Titanate ndeye polycrystalline zvinyorwa. Iko kune crystal yekristle interface pakati pekristaro yemukati uye yekristaro. Kana tembiricha yakaderera, maelector maitiro anogona kuyambuka nyore nyore iyo internet interface nekuda kweminda yemukati yemagetsi. Panguva ino, kukosha kwaro kunopesana kuchave kwakaderera. Kana tembiricha ichisimuka, munda wemukati uchaparadzwa, zvakaomera maelekitori anofambisa kuti ayambuke mutsara wezvinhu, uye kukosha kupokana kuchamuka panguva ino.

2) tembiricha isina kunaka coefficient thermistor (NTC)

NTC inowanzogadzirwa yezvinhu zvesimbi oxidei zvigadzirwa senge coballt oxide uye nickel oxide. Rudzi urwu rwe nziyo dzesimbi ine emagetsi mashoma nemakomba, uye kukosha kwaro kunopesana kuchakwira. Kana tembiricha ichisimuka, kuwanda kweasarudzo nemakomba mukati kuchawedzera uye kukosha kupikisa kuchaderera.

3. Zvakanakira muwarmista

Kunyanya kunzwa, tembiricha inoenderana neye thermistor inodarika 10-100 nguva yakakura kupfuura iyo yesimbi, uye inogona kuona kudziya kwekudziya kwe10-6; Yakakura inoshanda tembiricha, yakajairwa tembiricha yakakodzera ye -55 ℃ ℃ ℃ ℃ ℃ ℃ ℃ ℃ ℃, idiki muhukuru uye inogona kuyera tembiricha yenzvimbo iyo vamwe thermometers haigoni kuyera

4. Kushandiswa kwe Thermistor

Iko kushandisirwa kukuru kweiyo Thermistor kwakafanana ne tembiricha yekuona chinhu, uye tembiricha yekuona inowanzo kushandisa thermistor ine tembiricha isina kunaka, iyo, NTC. Semuenzaniso, kazhinji anoshandiswa zvishandiso zveimba, senge semucomputer yemupunga, induction cookers, etc., zvese shandisa thermisters.
