Sensor loogu talagalay mabda'a ballaarinta birta

dareemaha heerkulka

dareemaha heerkulka

Birtu waxay soo saari doontaa kordhin u dhiganta ka dib marka heerkulka deegaanku isbeddelo, markaa dareemaha wuxuu u rogi karaa calaamadda falcelintan siyaabo kala duwan. lix

Dareemayaasha Chip Bimetallic

Xaashida bimetallic waxay ka kooban tahay laba xabbadood oo bir ah oo leh is-ballaadhineedyo kala duwan oo isku dheggan. Iyada oo isbeddelka heerkulka, heerka balaarinta ee walxaha A ayaa ka sarreeya birta kale, taas oo keenta in xaashida birta ay leexiso. Qallooca qalooca waxa loo rogi karaa calaamad wax soo saar leh.

Ushii bimetal iyo dareeraha tuubada birta

Kordhinta heerkulka, dhererka tuubada birta (qalabka A) ayaa kordha, laakiin dhererka birta birta ah ee aan la fidin (birta B) ma aha, sidaas awgeed fidinta tooska ah ee tuubada birta ayaa la kala qaadi karaa sababtoo ah isbeddelka booska. Dhanka kale, balaadhintan toosan ayaa loo rogi karaa calaamad wax soo saar leh.

Dareemka naqshadeynta qalooca qalooca ee dareeraha iyo gaaska

Marka heerkulku isbeddelo, mugga dareeraha iyo gaasta ayaa sidoo kale isbeddeli doona si waafaqsan.

Noocyo kala duwan oo qaab-dhismeedyo ah ayaa isbeddelkan balaadhinta u beddeli kara beddelka boosaska, sidaas awgeed waxay soo saaraan wax-soo-saarka beddelka booska (potentiometer, leexasho la-abuuray, khalkhal, iwm.).

Dareenka iska caabinta

Isbeddelka heerkulka, qiimaha caabbinta ee birta ayaa sidoo kale isbeddelaya.

Biraha kala duwan, isbeddelka qiimaha iska caabbinta waa ka duwan yahay mar kasta oo heerkulku isbeddelo hal darajo, qiimaha caabbinta si toos ah ayaa loo isticmaali karaa sida calaamadda wax soo saarka.

Waxaa jira laba nooc oo isbeddellada iska caabin ah.

Isku xidhka heerkulka wanaagsan

Heerkulka sare u kaca = korodhka caabbinta

Heerkulka hoos u dhaca = iska caabbinta oo yaraada.

isku xidhka heerkulka xun

Heerkulka ayaa kordha = iska caabbinta ayaa yaraada.

Heerkulka hoos u dhaca = caabbinta ayaa korodha.

Dareenka Thermocouple

Heerkulbeeggu wuxuu ka kooban yahay laba fiilood oo bir ah oo walxo kala duwan ah, kuwaas oo la isku dhejiyay darafyada. Marka la cabbiro heerkulka deegaanka ee qaybta aan kululayn, heerkulka barta kuleylka ayaa si sax ah loo ogaan karaa. Sababtoo ah waa inay lahaataa laba kirishbooye oo walxo kala duwan ah, waxaa loo yaqaan thermocouple. Heerkulbeegyo ka samaysan walxo kala duwan ayaa loo isticmaalaa heerkul kala duwan, dareenkoodu sidoo kale wuu ka duwan yahay. Dareenka thermocouple waxa loola jeedaa isbeddelka kala duwanaanshaha wax soo saarka marka heerkulka barta kulaylku uu is beddelo 1℃. Heerkulbeegyada ugu badan ee ay taageerayaan walxaha birta ah, qiimahani wuxuu ku saabsan yahay 5 ~ 40 microvolts/℃.

Sababtoo ah dareenka dareeme heerkulka thermocouple waxba kuma laha dhumucda walxaha, waxa kale oo laga samayn karaa walxo aad u fiican. Sidoo kale, iyadoo ay ugu wacan tahay habacsanaanta wanaagsan ee walxaha birta ah ee loo isticmaalo samaynta kulaylka, curiyahan yar ee cabbiraadda heerkulka ayaa leh xawaare jawaab celin aad u sarreeya wuxuuna cabbiri karaa habka isbeddelka degdegga ah.
