PTC元件系列
1．產品形狀
2.用途及特點：
1．PTC熱敏陶瓷發熱元件有恒溫、調溫、自控溫的特殊功能
當對PTC元件施加交流或直流電壓時，在居裡點溫度以下，電阻率很低，升溫速度很快，當一旦超越居裡點溫度，電阻率突然增大，使其電流下降至穩定值，達到自動控制溫度、恒溫目的，不需另加溫度控制線路裝置，而且可根據不同的溫度要求通過配方來調整PTC元件的居裡溫度。
2．不燃燒、安全可靠
PTC元件發熱時不發紅，無明火（電阻絲發紅且有明火），不易燃燒。PTC元件周圍溫度超越限值時，其功率自動下降至平衡值，不會產生燃燒危險。
3．壽命長
PTC元件本身為氧化物陶瓷，無鎳鉻絲之高溫氧化弊端，也沒有紅外線管易碎現象，壽命長。
4．使用電壓范圍廣
PTC元件在低壓（3-36伏）和高壓（110-380伏）下都能正常使用。
低壓PTC元件適用於各類低電壓加熱器，機器低溫補償，汽車用各類加熱器。
高壓PTC元件適用於下列電氣設備的加熱：烘鞋器、熱熔膠槍、電飯煲、電熱靴、電熱驅蚊器、靜脈輸液加熱、輕便塑料封口機、蒸氣發梳、蒸氣發生器、加濕器、卷發器、錄象機、復印機、自動售貨機、、風幕機、暖手器、茶葉烘乾機、水管加熱器、旅行乾衣機、汽車烤漆房、液化氣瓶加熱器、、美容器、、奶瓶恒溫器、電熱炙療器、電熱水瓶、電熱。
1. PTC Element Series
1) Construction
2) Application&Characteristics:
1．PTC ceramic thermistor is functional in stabilizing,adjusting and controlling temperatures.
Loaded by alternating or direct current, the temperature of PTC soars up with low resistance value. However,when it exceeds curie temperature, the resistance value arises suddenly and the current would dro to a certain value. Thus temperature is stabilized. For PTC thermistor, additional temperature-control devices are not necessary any more.Besides, different curie temperatures are realizable by adjusting the formula of PTC.
2．Inflammable&Reliable
Compared with fuse, PTC components would not turn red nor on fire when heated.When the ambient temperature overpass the limit, its power would dro to equilibrium value so as to avoid burning.
3．Long life length
As oxide ceramics in nautre, PTC neither oxidize upon high temperature as nichrome wire,nor as fragile as infrared lamps.It is kind of components with long life length.
4. Wild Range of Voltage
PTC components could work normally under either low voltage（3～36V）or high voltage(110-380V).
The low voltage PTC component could be applied in all types of low pressure heaters,low temperature compensation appratus,vehicle heaters ect..
The high voltage PTC is suitable for all electric devices such as shoes drying machine, glue gun, electric cooker, electrothermic boots, mosquito repeller, venous transfusion heater,portable plastic sealer,steam comb,steam generator,humidifier,roller,vedio,copier,vending machine,air curtain, hand warmer, tea baker,pipe heater,dryer,bake painting house,liquefier heater,cosmetic steamer, feeder thermosat,electric acupuncture,electric thermos,electric blanket
