電磁加熱器(qi)IGBT溫度傳感器(qi)異常解決方法：

1、出現(xian)傳(chuan)感器(qi)異常(chang)后(hou)請先將(jiang)傳(chuan)感器(qi)引線主板上拔下，再用(yong)萬用(yong)表(biao)測量其阻值(zhi)，常(chang)溫25℃時阻值(zhi)應約為10K，否則傳(chuan)感器(qi)已(yi)損壞。

2、如傳感(gan)器(qi)正常，再檢測(ce)傳感(gan)器(qi)引線是(shi)否與(yu)CN3連(lian)接正常。C36、R16是(shi)否開、短(duan)路。

3、檢測U5第16腳(jiao)是否連接(jie)正常。

電(dian)磁加熱器(qi)用于油氣管道應用的特點：

1、熱效高：節能(neng)電磁加熱器不需(xu)要預熱管道(dao)。

2、不破壞管道保(bao)溫層(ceng)：由于是感應節能電磁加熱，磁力線能穿透保(bao)溫層(ceng)，改(gai)造(zao)管單。

3、安全(quan)性高：無明(ming)火(huo)，無熱(re)輻射，溫度可控(kong)。

4、操作(zuo)方便(bian)：在管道(dao)上纏上電(dian)磁線圈，做好溫度控溫探(tan)頭，調節控溫系統，開機調節即(ji)可(ke)自控加(jia)熱恒溫。

電磁加熱(re)器出現(xian)故障時的處理方法：

、通過故障代(dai)碼(ma)(ma)自(zi)行(xing)解決：正規生產(chan)廠家的電磁加熱設備如果出現(xian)(xian)故障都會有相應的故障代(dai)碼(ma)(ma)顯示(shi)，可以(yi)讓用戶(hu)目了然。出現(xian)(xian)問題該就可以(yi)根據使用說明書上(shang)面的故障代(dai)碼(ma)(ma)表找(zhao)相應的解決方(fang)法。當然，這需要(yao)用戶(hu)具備定的專(zhuan)業(ye)常(chang)識，就可以(yi)采用必要(yao)的措(cuo)施自(zi)行(xing)解決。

二、通(tong)過售后(hou)服(fu)務解(jie)決(jue)(jue)：般正規電磁加熱器(qi)廠(chang)家(jia)(jia)是免費(fei)保修年的(de)(de)(de)，自行解(jie)決(jue)(jue)不(bu)了(le)的(de)(de)(de)話，就(jiu)應該(gai)積(ji)與生產(chan)廠(chang)家(jia)(jia)或經(jing)銷商聯系，通(tong)過廠(chang)家(jia)(jia)的(de)(de)(de)售后(hou)服(fu)務來解(jie)決(jue)(jue)。好(hao)的(de)(de)(de)生產(chan)廠(chang)家(jia)(jia)都提供優質的(de)(de)(de)售后(hou)服(fu)務，能夠迅(xun)速幫(bang)用戶解(jie)決(jue)(jue)問(wen)題。

三、過保修(xiu)期，售(shou)后服務(wu)解決(jue)：還有(you)種就(jiu)是電磁加(jia)熱器的(de)保修(xiu)期已過后而出現了(le)故障，這種的(de)話(hua)你(ni)到當時售(shou)賣的(de)電磁加(jia)熱器廠家幫(bang)你(ni)維修(xiu)，般(ban)合理(li)收取維修(xiu)費用(正規廠家不會亂收費的(de))，但是如果你(ni)不是到該廠家購買(mai)的(de)也是可以維修(xiu)的(de)。

電(dian)磁(ci)加熱(re)器普通加熱(re)圈加熱(re)方式優勢(shi)：

1、接觸式(shi)熱(re)傳遞加熱(re)。

2、耗電的(de) 30-70% 轉(zhuan)化為工作(zuo)熱能。

3、加熱通(tong)過接觸方式(shi)傳遞熱能。

4、加熱及冷(leng)卻都有慣(guan)性(xing)現象產生，及升溫降溫都緩慢(man)。

5、加(jia)熱有死角，不能完全包裹在料筒外層。

6、加(jia)熱(re)圈損耗大，壽命短。

電(dian)(dian)(dian)磁(ci)加熱(re)(re)(re)簡介(jie)：電(dian)(dian)(dian)磁(ci)加熱(re)(re)(re)也(ye)稱電(dian)(dian)(dian)磁(ci)感應加熱(re)(re)(re)，即(ji)(ji)電(dian)(dian)(dian)磁(ci)加熱(re)(re)(re)(外文(wen):Electromagnetic heating縮寫：EH)技(ji)(ji)術，電(dian)(dian)(dian)磁(ci)加熱(re)(re)(re)的(de)原理是通過電(dian)(dian)(dian)子(zi)(zi)線(xian)路板組成部(bu)分產生(sheng)交(jiao)變磁(ci)場、當用含鐵(tie)質(zhi)容器(qi)(qi)放(fang)置上面時，容器(qi)(qi)表面即(ji)(ji)切割交(jiao)變磁(ci)力(li)線(xian)而(er)在容器(qi)(qi)底部(bu)金(jin)屬部(bu)分產生(sheng)交(jiao)變的(de)電(dian)(dian)(dian)流(liu)（即(ji)(ji)渦(wo)流(liu)），渦(wo)流(liu)使容器(qi)(qi)底部(bu)的(de)載流(liu)子(zi)(zi)高(gao)速無規則運動，載流(liu)子(zi)(zi)與原子(zi)(zi)互(hu)相碰撞、摩擦而(er)產生(sheng)熱(re)(re)(re)能(neng)。從而(er)起到加熱(re)(re)(re)物品的(de)效(xiao)果(guo)。因為是鐵(tie)制容器(qi)(qi)自身發(fa)熱(re)(re)(re)，所以熱(re)(re)(re)轉化率特(te)別高(gao)，高(gao)可達到95%是種直接(jie)加熱(re)(re)(re)的(de)方式。電(dian)(dian)(dian)磁(ci)爐(lu)，電(dian)(dian)(dian)磁(ci)灶 電(dian)(dian)(dian)磁(ci)加熱(re)(re)(re)電(dian)(dian)(dian)飯(fan)鍋都是采用的(de)電(dian)(dian)(dian)磁(ci)加熱(re)(re)(re)技(ji)(ji)術。
