Mainly suitable for accurately measuring the relative displacement of two points
SMG02 fiber grating displacement meter is mainly suitable for accurately measuring the relative displacement of two points. If a small-range displacement meter is selected, it can measure surface cracks and replace the crack meter, such as slip, settlement and cracks in tunnels, underground projects, slopes, building structures, etc., and can simultaneously measure the temperature of the buried point.
It is mainly composed of a core elastic structure, a spring, and a connecting rod. The connecting rod is connected to the test piece, and the displacement change is stretched by the spring. The other end of the spring is connected to the core elastic structure, which drives the elastic core structure to produce a tiny displacement, which is sensed by the internal grating and the change in reflected wavelength is detected by the background demodulator to achieve the measurement purpose.
Features
- Stability: All products are sealed with special sealant, which greatly reduces the probability of zero drift of traditional sensors. Traditional sensors have a high probability of zero drift due to continuous creep within 10 months.
- Temperature measurement function: The temperature compensation method is also different. The temperature compensation structure adopted not only has automatic temperature compensation function, but also can collect temperature.
- Long distance transmission, good product reliability.
