Abstract

This paper presents the optimized optical fiber sensor as a device allowing real-time monitoring of rotation of industrial machines parts such as shafts, impellers, compressors, mixers, etc. With proper configuration it is possible to continuously monitor the rotation frequency and phase, and thus synchronize the work of separate parts of machinery. The main principle or work is similar to standard open-head reflective sensors, but in this case head is shielded by special protective glass and immersive layer. In the paper, response curves for the different head models were shown. Also, the results of measuring and comparing the shape of the rotor blades were shown. Authors demonstrated sensor ability to measure the frequency and amplitude of the additional vibration of the rotor. For comparison, we also demonstrated a low amplitude micro-vibration measurement with a piezoelectric plate as other test object.
