Device for measuring deformations in an elongated machine component, especially the doctor beam of a coater
First Claim
1. In a device for measuring deformations in an elongated machine component, including a reference component that essentially extends along but is separated from the machine component and secured to it at each end and with a sensor that is positioned between the ends of the reference component and secured to the machine component, whereby the sensor reacts to a change in its distance from the reference component occasioned by a deformation in the machine component, the improvement wherein the reference component comprises a strip which is freely tensioned in a straight line, which is elastically deformable or is resiliently mounted, and which is secured only at its tensioned ends to the machine component, the sensor being a remote sensor that extends into the vicinity of the surface of the strip and emits a signal that is proportional to the distance of the sensor from the strip.

Abstract
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.
