www.vtt.fi Fiber Optics Sensors for Machine Condition Monitoring Fiber optic sensors have been developed for bearing pressure measurement and lubricant oil quality monitoring. These sensors are suitable for environments with electrical and magnetic disturbances. Business from technology Bearing pressure monitoring • Fiber optic pressure sensor has intensity based measurement for 0-1000 bar oil film pressure • Ability to verify speed and load effects at real operating conditions • Tested with journal and rolling bearings Lubricant oil quality monitoring • Fiber optic oil sensor based on absorption and fluorescence measurements • Absorption analysis sensitive to 1-50 µm metal particles • Capable to detect colour changes in lubricant oils • The change of optical signal indicates oil quality level
