說明 該傳感器采用熱釋電材料極化隨溫度變化的特性探測紅外輻射，采用雙靈敏元互補方法抑制溫度變化產(chǎn)生的干擾，提高了傳感器的工作穩(wěn)定性。
使用 1、上述特性指標(biāo)是在源極電阻R2=47KΩ條件下測定的，用戶使用傳感器時，可根據(jù)自己的需要調(diào)整R2的大小。
2、注意靈敏元的位置及視場大小，以便得到*光學(xué)設(shè)計。
3、所有電壓信號的測量都是采用峰一峰值定標(biāo)。平衡度B中的EA和EB分別表示兩個靈敏元的電壓輸出信號的峰一峰值。
4、使用傳感時，管腳的彎曲或焊接部位應(yīng)離開管腳基部4mm以上。
5、使用傳感器前，應(yīng)先參考說明書，尤其要防止接錯管腳
