Abstract

A transducer device for measuring mechanical values on hollow bodies, such as the internal pressure in pipes, by detecting deformation in the outer surface thereof, comprises a housing for removably enclosing the hollow body whose outer surface deformation is to be measured and at least one elastic sensor element which is capable of being elastically and at least indirectly pressed against the outer surface of the hollow body by an elastic endorsing element and capable of stretching due to the deformation of the hollow body due to frictional contact therewith. The endorsing element is combined with the sensor element and/or at least a part of the housing into one piece, whereby manufacture and adjustment of the transducer device are simplified.
