FBG strain sensor is a strain measurement sensor based on fiber Bragg grating. It can monitor the strain value of the measured object by measuring the spectral shifts of FBG.
• Suitable for application scenarios where traditional resistance strain gauges used
• Suitable for application scenarios where traditional surface-mounted resistance strain gauges used
• Suitable for harsh environments with the requirements of high anti-electromagnetic interference and explosion-proof
• Gauge length the same as standard resistance strain gauges
• Passive and free from electromagnetic interference
• High networking with series or parallel connected
• Lifespan >107 cycles (±1500μɛ)
• High stability, no zero-point drift
