Abstract
The invention provides a sensor, which includes a sensing surface; a housing including a recess, the sensing surface is located at the bottom of the recess, and the recess includes at least one side wall and an opening circumferentially surrounding the sensing surface. A compressed fluid nozzle is provided in the at least one side wall to nozzle compressed fluid from the compressed fluid nozzle to force the substance on the sensing surface to leave from the opening. This design makes it possible to refresh in situ with good efficiency without involving additional mechanical parts, thus reducing the risk of sensing surface damage, such as scratch wear, in the presence of wear particles.
