Deformation measuring device for monitoring bridge supports, machine stands etc. - has coupling elements positively interlocked with surface of monitored part, e.g. via corrugations

摘要

The measurement device (2), e.g. a diaphragm with strain gauges, is placed between two coupling elements (6,7) associated with the component (10). Deformations of the measurement device are detected by measurement elements and used to determine deformations of the component. A flexurally weak transfer element (8) is arranged between at least one coupling element and the measurement device. The coupling elements and the associated regions of the component have surface structures enabling force-locking connection of the coupling elements and component, e.g. via corrugations. ADVANTAGE - Simple, robust arrangement produces accurate, reproducible measurement results.
