摘要：摘要本文通過采用熱敏電阻作為敏感元件的溫度報警器的設計與制作，闡明了該裝置進行設計與

制作的具體過程及方法。這種溫度報警器結構簡單，由溫度控制開關和報警器兩部分組成，可操作性強

，應用廣泛。工作時，溫度測量范圍為0～100ºＣ。當溫度達到預定值時，利用熱敏電阻的特性，采集電

壓信號，驅動報警裝置，立刻發出報警信號，從而防止因溫度升高而帶來的不必要的損失。

關鍵詞：熱敏電阻、溫度、報警器、金屬探頭

Abstract: This thesis introduces the design and the manufacture of the heat alarm by using

the thermistor as the sensitive unit, has expounded the concrete process and the method

which this equipment carries on the design and the manufacture. This kind of heat alarm the

structure is simplewhich is composed by two parts, the temperature control switch and the

alarm apparatus, it is feasibility and the application is widespread. When it works, the

survey scope of the temperature is 0 ~ 100 ºC. When the temperature achieves the

predetermined value, using the thermistor characteristic to gather the voltage signal,

actuates alarm device and sends out the alarm immediately, thus prevents the nonessential

loss which brings by temperature increment.
