# 2.3.1溫度感應器

本產品內建二組PT1000 溫度感測器連接介面提供精確的管路上下熱能表延伸應用，相關使用注意事項如下： 

● 請使用二線式PT1000 感測器，不相容於PT500、PT100。 

● 儀表提供量測範圍為-100\~300℃。感測器的品質與精度會直接影響溫度的量測結果請選擇正確且適用的溫度測元件。 

● 感測器不分極性，但有區分上下游，安裝時請注意。 

● 線材長度建議小於3 公尺，過長將影響量測精度。 

● 線材經過處盡量遠離任何有可能產生電磁波雜訊的儀器或裝置。例如大電電纜，馬達，配電盤，變頻器。線材與產品接頭務必牢固鎖緊不良的接觸可能產生電阻而影響量測結果。
