B59100M1145A070屬于傳感器，變送器 > 溫度傳感器 - PTC 熱敏電阻。愛普科斯與TDK元件事業(yè)部制造生產(chǎn)的B59100M1145A070溫度傳感器 - PTC 熱敏電阻正溫度系數(shù) (PTC) 熱敏電阻溫度傳感器是隨著溫度升高而呈現(xiàn)出電阻增加的器件。與許多其他溫度傳感器類型相比，熱敏電阻產(chǎn)生的輸出信號相對較大且易于測量，但它們往往具有不穩(wěn)定且不適合精確溫度測量的特征。PTC 熱敏電阻尤其適合于過熱檢測應用，并且通常表現(xiàn)出明顯的非線性溫度-電阻關(guān)系，因此可用于檢測不精確的“高”溫條件，但不適于進行精確測量。
