PTC thermistor alloy waya wa ohun elo ni awọn aaye pupọ nitori awọn abuda alailẹgbẹ rẹ. Eyi ni diẹ ninu awọn ohun elo ti o wọpọ ti PTC thermistors:

Idaabobo lọwọlọwọ: PTC thermistors ti wa ni lilo pupọ ni awọn iyika itanna fun aabo lọwọlọwọ. Nigbati agbara giga ba nṣan nipasẹ thermistor PTC, iwọn otutu rẹ pọ si, nfa ki resistance lati dide ni iyara. Yi ilosoke ninu resistance idinwo awọn ti isiyi sisan, idabobo awọn Circuit lati bibajẹ nitori nmu lọwọlọwọ.

Wiwa iwọn otutu ati iṣakoso: PTC thermistors ti wa ni lilo bi awọn sensọ iwọn otutu ni awọn ohun elo bii thermostats, awọn ọna ṣiṣe HVAC, ati awọn ẹrọ ibojuwo iwọn otutu. Awọn resistance ti thermistor PTC yipada pẹlu iwọn otutu, gbigba o laaye lati ni oye deede ati wiwọn awọn iyatọ iwọn otutu.

Awọn igbona ti n ṣatunṣe ti ara ẹni: Awọn iwọn otutu PTC ti wa ni iṣẹ ni awọn eroja alapapo ti ara ẹni. Nigbati a ba lo ninu awọn igbona, resistance thermistor PTC pọ si pẹlu iwọn otutu. Bi iwọn otutu ti n dide, resistance ti thermistor PTC tun pọ si, ti o yori si idinku ninu iṣelọpọ agbara ati idilọwọ igbona.

Ibẹrẹ mọto ati aabo: Awọn iwọn otutu PTC ni a lo ni awọn iyika ibẹrẹ motor lati ṣe idinwo lọwọlọwọ inrush giga lakoko ibẹrẹ motor. Thermistor PTC n ṣiṣẹ bi aropin lọwọlọwọ, diėdiẹ jijẹ resistance rẹ bi ṣiṣan lọwọlọwọ, nitorinaa aabo mọto lati lọwọlọwọ pupọ ati idilọwọ ibajẹ.

Idaabobo idii batiri: Awọn iwọn otutu PTC ti wa ni iṣẹ ni awọn akopọ batiri lati daabobo lodi si gbigba agbara pupọ ati awọn ipo lọwọlọwọ. Wọn ṣe bi aabo nipa didiwọn sisan lọwọlọwọ ati idilọwọ iran ooru ti o pọ ju, eyiti o le ba awọn sẹẹli batiri jẹ.

Inrush lọwọlọwọ aropin: PTC thermistors ṣiṣẹ bi inrush lọwọlọwọ limiters ni agbara ati awọn ẹrọ itanna. Wọn ṣe iranlọwọ lati dinku iṣẹda ibẹrẹ ti lọwọlọwọ ti o waye nigbati ipese agbara ba wa ni titan, aabo awọn paati ati imudarasi igbẹkẹle eto.

Iwọnyi jẹ apẹẹrẹ diẹ ti awọn ohun elo nibiti a ti lo okun waya thermistor Alloy PTC. Ohun elo kan pato ati awọn ero apẹrẹ yoo pinnu ohun elo alloy gangan, ifosiwewe fọọmu, ati awọn aye ṣiṣe ti thermistor PTC.
