Gas sensor used for determining concentration and temperature of exhaust gas component of IC engine comprises guiding element arranged in recess of contact holder facing contact surface of sensor element

摘要

A gas sensor comprises a guiding element (23) arranged in a recess (26) of a contact holder (24) facing the contact surface (22) of the sensor element (21). A region protruding from the recess is in contact with the contact surface interacting with a spring element (25). Preferred Features: The guiding element protrudes with less than half its cross-sectional surface from the recess. The spring element is an elastic hollow cylindrical element. The contact holder is made from Al2O3.
