The invention relates to a sensor assembly (11) comprising a deformation element (111) with two opposing surfaces (111+, 111#), an outer edge segment (111a), and a sensor vane (112) which extends from the surface (111+) up to a distal end and which comprises a left-side first lateral surface (112+) and a right-side second lateral surface (112#). The sensor assembly (11) further comprises an overload protection device (113), which extends from said edge segment (111a) up to a distal end, can be used to protect the deformation element (111) against plastic or irreversible deformation, and comprises a support bracket (113a) that is guided at a lateral distance from the sensor vane, and two stops (113b, 113c), which are supported on the support bracket for the sensor vane (112), wherein a first stop (113b) of the stops is placed on the left-hand side of the sensor vane and a second stop (113c) of the stops is placed on the right-hand side of the sensor vane. The stops (113b, 113c) are dimensioned and arranged such that an intermediate space (113') formed between the stops takes up solely a sub-region (112a) of the sensor vane (112). The deformation element and the sensor vane are additionally designed to vibrate about a common static rest position and in the process move relative to the overload protection device such that the sensor vane carries out oscillating movements which elastically deform that deformation element and during which the sub-region (112a) is alternately moved to the left, namely in the direction of the stop (113b), or to the right, namely in the direction of the second stop (113c). A sensor made with such a sensor assembly and a transducer element (12), which is coupled thereto and functions so as to generate a sensor signal that represents temporally changing movements of the sensor vane and/or temporally changing deformations of the membrane, or a measuring system made with said sensor and a measuring electronic system connected thereto can be used to detect pressure fluctuations in a flowing fluid, for example in a steam with an at least temporary temperature of 400 ºC and/or an at least temporary pressure of more than 140 bar, in order to measure a flow parameter of said fluid for example. |
