Abstract
A gas measurement probe has a casing (11) equipped with a closure shell (17) on its end away from the gas to be measured. At the other end of the casing, within its longitudinal bore, a sensor element (24) is held fast and tight in the casing. A rod-shaped part carrying a heater element fits within the sensor element and extends out of it at its end away from the gas to be measured to an extremity near which contact areas are provided on its periphery. On these contact areas, resilient connection wires lie under mechanical bias. These wires, between the loops bearing against the contact surface and their ends are bent in Z or sinuous shape so as to secure them against pulling, twisting and shaking forces. These connection elements and also another conductor running in the probe cooperate with an indexing feature of the rod-shaped element, such as a suitable groove to secure the rod-shaped component against twisting. This construction is particularly suitable for probes utilizing a solid electrolyte tubular sensor element closed at its tip.
