安徽環瑞是自控溫電熱帶，恒功率電熱帶均生產的電熱帶廠家，而自控溫電熱帶和恒功率電熱帶的溫度范圍基本上覆滿足了電廠，化工，石油等管道電伴熱的需求，在自控溫和恒功率電熱帶溫度范圍重疊時候，是否精確控是選擇電熱帶型號的重要依據，小編在這里提幾點建議：
首先，需了解自控溫電熱帶和恒功率的伴熱原理，
自控溫電熱帶可以不需要溫控器就能自動控溫，而這自動控溫維持的最終溫度是根據環境溫度、管內介質的溫度，外保溫的情況，確定最終的溫度，相對比較自由。在不同情況下的相同介質的管道即使在使用相同的電熱帶產品，維持的溫度也不一樣。而自控溫電熱帶的維持溫度不會超過65度或105度，這也是自控溫電熱帶又稱為自限溫電熱帶的原因。
小結：自控溫電熱帶一般用于溫度不需精確的管道電伴熱，若需精確溫控的話，需采用電熱帶專用防爆溫度控制器，但是小編并不推崇，會導致自控溫電熱帶啟動過多。
恒功率電熱帶是傳統電熱帶產品，是采用電阻絲發熱，所以必須使用防爆溫控器加以控制溫度，溫度范圍可精確到實際維持溫度的正負2度。若在無溫控器或者溫控器壞掉的情況下，溫度會逐步升高，一直到芯帶燒毀為止。
小結：恒功率電熱帶必須使用溫度控制器加以控制。
總結：兩者電熱帶加以比較可以說明：是否使用溫度控制器需考慮維持溫度是否精確為前提，做到遵循電熱帶的特性。
產品的創新，也隨之理念的更新。因為自控溫電熱帶已經取代恒功率電熱帶，成為管道電伴熱的主力軍。我們推薦廣大客戶使用自控溫電熱帶,而我們安徽環瑞自控溫電熱帶 恒功率電熱帶資質齊全，工程案例額豐富：
