Gauge with a flexible window cover

The bimetal thermometer according to the invention comprises a bimetal helix arranged inside a protective tube, one end thereof being attached to the protective tube and the other end thereof being connected to a pointer shaft to which a pointer arranged inside a casing is attached. The pointer shaft is rotatably journaled in a bearing assembly in which a cavity is formed through which the pointer shaft extends. The cavity is filled with semisolid lubricating grease for damping vibration movements of the pointer shaft. The pointer shaft has either a smooth surface or is provided with at least one radial projection arranged inside the cavity. Vibration movements of the pointer shaft are damped by the interaction of the pointer shaft and, if provided, the projections with the viscous lubricating grease. This design of the bearing assembly and the pointer shaft permits to provide a damped bimetal thermometer without a liquid filling being required in the casing and the protective tube or at least in the protective tube for the purpose of damping.
