Sensor probe particularly for vehicle exhaust gas measurements e.g. oxygen concentration or temperature, has a cable entry sealed by an elastomeric plug which is radially biased by a central spring

摘要

A measurement probe for high temperature gases, has a housing (15) containing a sensor element (11) with connection-cable insulated conductors (12) entering through channels (19) in an elastomeric plug (16) which also has a central blind recess (20) in which is mounted a radially acting coiled plate spring (21).
