Abstract
In a sensor assembly, a deformation body has two oppositely lying surfaces, an outer edge segment and a sensor blade extending from a surface outward. A protective apparatus protects the deformation body from pressure surges or abrupt changes of temperature on its surface. The protective apparatus includes at least one plate, extending radially inwardly so that a cavity is formed, which accommodates a region of the sensor blade adjoining the deformation body and remote from the distal end of the sensor blade, forming a gap between the plate and sensor blade. A sensor formed by the sensor assembly and a transducer element coupled therewith can be used for registering pressure fluctuations in a flowing fluid, such as steam having a temperature of 400 C and/or, a pressure of greater than 140 bar in order to measure flow parameters of the fluid.
