Abstract

This paper presents intensity optoelectronic sensor for vibration measurements based on fiber loop (macro-bend) with a fixed inertial mass - so-called "seismic mass". In harmful environments such as refineries and petrochemical factories applying traditional measurement methods may be difficult because of electric current which creates risk of fire and influence of electromagnetic noise on this electronic devices. Presented sensor is used to measure both the displacement, velocity and acceleration of the tested objects and the frequency of vibration. In addition, the sensor head allows placement in large distances from the apparatus receiving a signal through the low-loss and insensitive to electromagnetic interference optical fiber connections.
