Ubale Pakati pa Thermistor Ndi Sensor Kutentha

Onse sensa kutentha ndi thermistor angagwiritsidwe ntchito kuyeza kutentha.Kodi zimagwirizana bwanji?Kodi ndi chipangizo chomwecho, chongotchulidwa mosiyana?

Thermistorndi chopinga chopanda mzere chopangidwa ndi zinthu za semiconductor, ndipo kukana kwake kumakhudzidwa ndi kutentha.Mumtundu wina wa kutentha, kukana kumasintha ndi kusintha kwa kutentha.Thermistor ili ndi ubwino wa kutentha kukana kutentha, kukula kochepa, kuyankha mofulumira, kuchita bwino, ndi zina zotero, ndipo ingagwiritsidwe ntchito pamagetsi amagetsi azachipatala, kufufuza kutentha kwamagetsi ogula, etc.

Sensa ya kutentha imatanthawuza sensa yomwe imatha kuzindikira kutentha ndikusintha kutentha kukhala chizindikiro chogwiritsidwa ntchito.Mukamagwiritsa ntchito sensor ya kutentha, mutha kudziwa kuchuluka kwa kutentha komwe kumayezedwa poyesa kukula kwa chizindikiro chamagetsi.Sensa ya kutentha imagawidwa kukhala: semiconductor diode sensor, thermocouple sensor, thermistor sensor malinga ndi zinthu.

Mfundo yogwira ntchito ya sensa ya kutentha: chitsulo chimagwira molingana ndi kutentha kwapakati pakusintha, ndipo sensa ya kutentha imatha kusintha chizindikiro cha kusintha kwa kutentha m'njira zosiyanasiyana ndikuchitulutsa.Zowunikira kutentha zimagwiritsidwa ntchito kwambiri pamakina owongolera mpweya, mafiriji, zophika mpunga, mafani ndi zida zina zapakhomo, komanso m'makampani, ndege, chitukuko chapamadzi ndi zina.

Pamene thermistor imayeza kutentha ngati sensa ya kutentha, pamene kutentha kumasintha, mtengo wake wotsutsa umasinthanso ndi kutentha.Kupyolera mu dera la mlatho kapena dera losavuta lamagetsi, kusintha kwa magetsi kungasinthidwe kukhala chizindikiro cha voteji, ndipo chizindikiro chamagetsi chikhoza kulowetsedwa mu microcontroller ndi A / D converter kuti ayeze ndi kulamulira kutentha.

Ndiko kunena kuti, thermistor palokha ndi sensa ya kutentha, koma kutentha kwa kutentha sikuli kwenikweni thermistor, kutentha kwa kutentha kungakhalenso thermocouple, analogi thermometer IC.

Sankhani wopanga wodalirika pogula ma thermitors angapewe zovuta zambiri zosafunikira.JYH HSU (kapena Dongguan Zhixu Electronics) sikuti ili ndi mitundu yonse ya ma capacitor a ceramic okhala ndi mtundu wotsimikizika, komanso imaperekanso kutsatsa kopanda nkhawa.Takulandilani kuti mutitumizire pafunso lililonse kapena mgwirizano wamabizinesi.
