PRODUCT CENTER
SM The G04 fiber optic grating anchor cable meter is mainly used for measuring the load of anchor cables, rock anchor bolts, anchor ties, or arched supports, as well as other heavy loads.
The anchor cable meter itself is a high-strength alloy steel cylinder, Different load anchor cable force meters have built-in 3～6 high-precision vibrating string sensors. The sensors can monitor the total load acting on the anchor cable force meter. At the same time, by measuring the change of each sensor, uneven load or eccentric load can also be obtained. The built-in temperature sensor has a temperature measurement function, and a dedicated multi-core anti-interference shielded cable is used to transmit electrical signals containing load and temperature information, and the measured value is not affected by the cable length. With good stability and a fully waterproof and sealed structure design, it is suitable for long-term monitoring of anchor cable load changes in various harsh environments.
Features
- Easy installation, can be used for both monitoring and short-term monitoring, and can be reused;
- Suitable for projects with small changes in ambient temperature, less wavelength bandwidth resources are occupied, high batch practicality, and saving the overall project cost;
- The tail fiber adopts PU jacketed armored optical cable, which has excellent temperature resistance, corrosion resistance, and aging resistance, and is suitable for outdoor survival environments;
- Good stability and high reliability.
