Monitoring optically powered actuators

Monitoring optically powered actuators

Operation of a power-by-light valve by a source along an optical fibre is monitored by means of optical sensors from which light passes back along fibre to monitoring and processing units. The sensors include fibre bragg gratings for detecting differential pressure across diaphragms and for detectin...

description Operation of a power-by-light valve by a source along an optical fibre is monitored by means of optical sensors from which light passes back along fibre to monitoring and processing units. The sensors include fibre bragg gratings for detecting differential pressure across diaphragms and for detecting temperature. At the input end, an optical coupler supplies sensor signals to units which can control source via a signal.
