摘要

Preliminary results of the tests performed by using a modular fiber-optic sensor for hydrostatic pressure/temperature and also rotation measurements envisaged for refinery applications are presented. The prototype fiber optic sensor for rotation measurements has been successfully installed and tested in the ORLEN Refinery in Plock, Poland. During the initial tests, we used a rotating machine to measure its rotor velocity whereas the sensor head was connected to a pigtailed laser diode (λ=635 nm) and to a detector by a 100-meters-long loop of multimode optical fibers. The output signals of the optical sensor were transferred into a refinery automatic control system (-2 or -20 V). During tests in the ORLEN Refinery we obtained very good agreement of output signals from standard magnetic sensor and the proposed optical sensor. In addition, the proposed optical fiber rotation sensor was immune to electromagnetic noise that disturbs output signals of the magnetic sensors.
