Fiber Bragg Grating Sensor/SMG03 Fiber Bragg Grating Surface Mount Strain Gauge

SMG03 fiber grating surface mounted strain gauge is mainly used for stress and strain monitoring of concrete surface, and also for static and dynamic stress and strain monitoring of various metal or other solid structure surfaces. The product adopts a unique elastic beam structure and has high measurement resolution and measurement.

This sensor is suitable for strain monitoring on surfaces in various environments. Our company has designed two packaging mechanisms for sensors according to different application environments and requirements: one is epoxy resin packaging, which can be used continuously for about one year. After expiration, creep may occur and it is not suitable for long-term monitoring, but it can meet short-term laboratory conditions; the other is oxygen-free glue packaging, which can be used for a long time.

Features

1. Easy to install, can be used for both real-time and short-term monitoring, and can be reused;
2. It is suitable for projects with small changes in ambient temperature, occupies less wavelength bandwidth resources, has high batch practicability, and saves overall project costs;
3. The pigtail uses PU-coated armored optical cable, which has excellent heat resistance, corrosion resistance and aging resistance, and is suitable for outdoor survival environments;
4. Good stability and high reliability.
