Abstract
본 발명은 반도체식 가스 센서 등에 사용되는 기판을 제공하기 위한 것으로, 세라믹 PTC 발열체로 된 정온 발열체 기판의 양면에 사각형상의 발열체 전극이 도포되어 있고, 상기 전극의 일면에 알루미나 절연층이 형성되어 있으며, 상기 알루미나 절연층 상에 통상의 경우와 같이 전극 및 감지 물질이 각각 인쇄되어 있는 정온 발열체를 기판으로 사용한 센서 소자인 것이다.The present invention is to provide a substrate for use in a semiconductor gas sensor or the like, a rectangular heating element electrode is coated on both sides of the constant temperature heating element substrate made of a ceramic PTC heating element, an alumina insulating layer is formed on one surface of the electrode, It is a sensor element using a constant temperature heating element on which an electrode and a sensing material are respectively printed on the alumina insulating layer as a substrate.
본 발명에 따른 센서 소자는 외부 분위기의 영향을 받지 않고, 안정적인 온도를 유지시켜 주는 정온 발열체 기판을 사용하고 있음으로 소자를 항상 일정 온도로 가열할 수 있어서 사용 온도에 따라 특성 변화가 있는 소재에 대해 정확한 작동 특성을 얻을 수 있게 된다.The sensor element according to the present invention uses a constant temperature heating element substrate that maintains a stable temperature without being influenced by an external atmosphere, so that the element can be heated to a constant temperature at all times, and thus the material having a characteristic change depending on the use temperature. Accurate operating characteristics can be obtained.
