Method for inspecting the quality of a gas sensor, related manufacturing method, and related inspecting apparatus |
摘要 |
An impact force is applied to a sensing element to enlarge the size of a hidden crack to a visible level to reveal the presence of a hidden crack. To apply the impact force to a sensing element, a gas sensor is supported by a holder which is fixed to a distal end of a shaft. The shaft swings about a proximal end thereof serving as a pivot. The holder, with the gas sensor held at its end, is released from a predetermined higher position so as to swing downward about the pivot of the shaft due to gravity. The holder hits a striking plate disposed on a swing path of the holder.
