Abstract
A sensing mechanism for determining the open or closed condition of a valve member located at a remote location. First and second optical fiber sections are aligned with a rotatable light modulator between the sections. Rotational movement of the modulator is governed by movement of a portion of the valve such that the light transmitted through the modulator may be detected to provide an indication of valve condition.
