Aiki na Thrmistor

1. Thermistor shi ne mai tsayayya da aka yi da kayan musamman, da darajar juriya yana canzawa tare da zazzabi. Dangane da ingantaccen tsarin juriya na juriya, an kasu kashi biyu:

Nau'in guda ana kiranta tabbatacce yanayin zafi mai kyau (PTC), darajar tsayayya da ƙimar zazzabi;

Sauran nau'in ana kiranta mara kyau zazzabi (NTC), wanda ƙididdigar ta rage tare da ƙara yawan zafin jiki.

2. Hermistor aiki manufa

1) tabbatacce yawan zafin jiki mai kyau (PTC)

PTC an yi shi da taken bari a matsayin babban abu, da kuma karamin adadin abubuwan duniya an ƙara su zuwa maniyium titanate. Bariium titanate abu abu ne mai polycrystalline. Akwai mai samar da barbashi tsakanin crystal na ciki da lu'ulu'u. Lokacin da zazzabi ya ragu, iyalan masu sarrafawa zasu iya ƙetare hanyar da aka sanya ta hanyar dubawa mai sauƙi saboda filin lantarki na ciki. A wannan lokacin, darajar juriya zai zama karami. Lokacin da zazzabi ya tashi, za a lalata filin cikin gida mai wahala, yana da wuya a haye mai kula da ƙwayar cuta, da darajar juriya za ta tashi a wannan lokacin.

2) mara kyau zazzabi mai amfani da zafi (NTC)

NTC ne aka yi shi da kayan aikin ƙarfe na ƙarfe kamar cobalt oxide da nickel oxide. Irin wannan nau'in oxide yana da karancin wayoyi da ramuka, da darajar juriya zai fi girma. Lokacin da zazzabi ya tashi, yawan wayoyin lantarki da ramuka a ciki zasu karu da darajar juriya zai ragu.

3. Fa'idodin Mermistor

Babban jijiya, yawan zafin jiki mai dacewa na Thermistor ya fi sau 10-100 ya fi girma fiye da na ƙarfe, kuma na iya gano canje-canje na zazzabi na 10-6 ℃; Na'urar yawan zafin jiki mai yawa, na'urorin zazzabi na yau da kullun sun dace da -55 ℃ ~ A yanzu haka ne ya dace da shekaru 31000 ℃), na'urar mawuyaci zata dace da -273 ℃ ~ ~. Yana da ƙanana cikin girma kuma yana iya auna zafin jiki na sarari da sauran thermometers ba zai iya matsawa ba

4. Aikace-aikacen Thermistor

Babban aikace-aikacen mai zafin jiki yana da tushen zazzabi na zazzabi, da kuma gano zafin jiki yawanci yana amfani da matsakaicin matsakaicin mai amfani da zazzabi, shine, NTC. Misali, kayan aikin gida wanda aka yi amfani da shi, kamar masu busa ƙaho, masu cookerena, da sauransu, duk suna amfani da thermistors.
