DEVICE FOR MEASURING DEFORMATIONS IN AN ELONGATED MACHINE COMPONENT, ESPECIALLY THE DOCTOR BEAM OF A COATER

摘要

A device for measuring deformations in an elongated machine component, especially the doctor beam of a coater. A strip that can be elastically deformed or is resiliently mounted longitudinally and is secured to the machine component only at its tensioned ends is tensioned independent and in a straight line at a distance from the machine component. A sensor that measures any variation in its distance away from the strip is rigidly mounted on the component between the two ends of the strip.
