Abstract
본 발명은 칩형 가스센서에 관한 것으로, 좀 더 구체적으로는 150∼200℃에서 정온 동작되는 PTC기판, 상기 기판, 상·하면에 형성된 발열용 전극, 절연체, 센서용 전극, 감가스물이 순차적으로 형성된 것을 특징으로 하는 칩형 가스센서에 관한 것이다.The present invention relates to a chip-type gas sensor, and more specifically to a PTC substrate, the substrate, the heating electrode formed on the substrate, the upper and lower surfaces, the insulator, the sensor electrode, the degassing material are sequentially formed at 150 ~ 200 ℃ It relates to a chip-type gas sensor characterized in that.
본 발명의 가스센서는 박막의 감가스물이 도포된 칩형 가스센서로서 구조가 단순하고 PVD법에 의해 촉매의 종류와 양에 상관없이 첨가될 수 있어 센서 동작 온도롤 200℃이하로 하더라도 목적하는 감도 특성을 얻을 수 있고 이에 따라 PCB 회로 상에 직접 장착할 수 있을 뿐만아니라 센서 자체의 특성 열화가 매우 작은 장점이 있다. 또한 기판으로 사용되는 PTC 히터는 외부 환경의 영향을 받지 않고 센서를 일정한 온도로 유지시켜 주므로 센서 특성이 매우 안정되고 히터 코일일 필요없게 되어 센서 양산시에도 경제성이 높은 것이 특성이다.The gas sensor of the present invention is a chip-type gas sensor coated with a thin gas-sensitive gas, and its structure is simple and can be added regardless of the type and amount of the catalyst by PVD method. In addition, it can be directly mounted on the PCB circuit, and the characteristic deterioration of the sensor itself is very small. In addition, the PTC heater used as the substrate keeps the sensor at a constant temperature without being influenced by the external environment, so the sensor characteristic is very stable and the heater coil does not need to be a heater coil.
또한, 상기 센서 소체는 기판과 가열 소자, 감가스물 및 전극이 일체형으로 구성되어 있어서 취급이 용이하고, 칩형태로서 크기를 임으로 조절할 수 있는 장점이 있다.In addition, the sensor element has an advantage in that the substrate and the heating element, the gas-sensitive material and the electrode is integrally formed to be easily handled and can be arbitrarily adjusted in size as a chip form.
