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

Differences Between Single-Mode and Multi-mode Fiber Optic Transceivers
13 Apr 2024
When it comes to choosing the right fiber optic transceiver for your network, one of the key decisions you'll need to make is whether to go with a single-mode or multi-mode transceiver. Both types...
