熱電偶工作原理;
兩種(zhong)不同成(cheng)份的(de)(de)導(dao)體(稱(cheng)為(wei)(wei)熱電(dian)(dian)(dian)偶絲材或熱電(dian)(dian)(dian)極(ji))兩端(duan)(duan)(duan)接(jie)合成(cheng)回(hui)路,當(dang)接(jie)合點的(de)(de)溫(wen)度(du)不同時,在回(hui)路中(zhong)就會產(chan)生電(dian)(dian)(dian)動勢,這(zhe)種(zhong)現象稱(cheng)為(wei)(wei)熱電(dian)(dian)(dian)效應,而(er)這(zhe)種(zhong)電(dian)(dian)(dian)動勢稱(cheng)為(wei)(wei)熱電(dian)(dian)(dian)勢。熱電(dian)(dian)(dian)偶就是(shi)利用這(zhe)種(zhong)原(yuan)理進行溫(wen)度(du)測(ce)量(liang)(liang)的(de)(de),其中(zhong),直接(jie)用作(zuo)測(ce)量(liang)(liang)介質溫(wen)度(du)的(de)(de)一端(duan)(duan)(duan)叫(jiao)做(zuo)工作(zuo)端(duan)(duan)(duan)(也稱(cheng)為(wei)(wei)測(ce)量(liang)(liang)端(duan)(duan)(duan)),另一端(duan)(duan)(duan)叫(jiao)做(zuo)冷端(duan)(duan)(duan)(也稱(cheng)為(wei)(wei)補償端(duan)(duan)(duan));冷端(duan)(duan)(duan)與顯(xian)示儀(yi)(yi)表(biao)(biao)或配套儀(yi)(yi)表(biao)(biao)連接(jie),顯(xian)示儀(yi)(yi)表(biao)(biao)會指出(chu)熱電(dian)(dian)(dian)偶所產(chan)生的(de)(de)熱電(dian)(dian)(dian)勢。 感(gan)謝你(ni)瀏覽(lan)本(ben)公司,您(nin)當(dang)前瀏覽(lan)的(de)(de)是(shi)熱電(dian)(dian)(dian)偶產(chan)品頁(ye)面,如果你(ni)對(dui)本(ben)司銷售的(de)(de)產(chan)品感(gan)興趣的(de)(de)話,溫(wen)馨(xin)提醒(xing)您(nin):可(ke)以我司了解更多相關產(chan)品的(de)(de)詳細信(xin)息(xi),我們的(de)(de)工作(zuo)人(ren)員定(ding)當(dang)竭(jie)盡全(quan)力的(de)(de)為(wei)(wei)您(nin)服務(wu)。
