OXYGEN SENSOR |
摘要 |
An oxygen conductive solid electrolyte plate has first and second opposite surfaces. First and second electrodes fixedly extend on the first and second surfaces of the electrolyte plate respectively. A spacing frame hermetically secured to the first surface of the electrolyte plate surrounds the first electrode. The spacing frame has an opening. A sealing plate hermetically secured to the spacing frame defines a chamber in conjunction with the electrolyte plate and the spacing frame. The chamber accommodates the first electrode and opens into an environment only via a window defined by the opening in the spacing frame. The window allows oxygen molecules to flow from the environment into the chamber by diffusion. |
