Device and method for measuring a rotational movement, in particular a rotational direction, and for detecting a shaft break
First Claim
1. A turbomachine comprising:
- a rotatable shaft;
a device for measuring a rotational movement of the rotatable shaft, wherein the device comprises;
a receiver and a first pattern carrier that includes a first pattern site,a second pattern carrier that includes a second pattern site,wherein the first and second pattern carriers are respectively connectable or connected to the rotatable shaft, so that they are rotatable together about a rotational axis with respect to the receiver such that the first pattern site is positioned in congruence with the second pattern site, andwherein the receiver is embodied and configured for detecting whether or not the first and second pattern sites are positioned in congruence with one another,wherein the first pattern carrier is arranged radially inside the second pattern carrier, wherein the second pattern carrier forms a part of the rotatable shaft.

Abstract
A turbomachine with at least one rotatable shaft and at least one device for measuring a rotational movement of a rotatable structural component), in particular of the shaft, is provided. The device has a receiver and a first pattern carrier that has at least one pattern site. Here, the device comprises a second pattern carrier with at least one pattern site, wherein the pattern carriers are respectively connectable or connected to the rotatable structural component, so that they are rotatable together with the same about a rotational axis with respect to the receiver, namely in such a manner that the pattern site of the first pattern carrier is positioned in congruence with the pattern site of the second pattern carrier, and wherein the receiver is embodied and configured for detecting whether or not the pattern sites are positioned in congruence with one another.

17. A method for measuring a rotational movement of a rotatable shaft of a turbomachine comprising:
-
providing a receiver and a first pattern carrier that includes a first pattern site, providing a second pattern carrier that includes a second pattern site, providing that the first and second pattern carriers are respectively connected to the rotatable shaft, so that they are rotatable together about a rotational axis with respect to the receiver such that the first pattern site is positioned in congruence with the second pattern site, and wherein the receiver detects whether or not the first and second pattern sites are positioned in congruence with one another, providing that the first pattern carrier is arranged radially inside the second pattern carrier, and that the second pattern carrier forms a part of the rotatable shaft. - View Dependent Claims (18)
