MAS-CCT EM Sensor
MAS-CCT-xx series EM sensors are used to measure and monitor the cable force components in various projects such as anchor rods, anchor cables, prestressed steel beams, arch bridge hanger rods, tie-rod cable of cable-stayed bridges, suspension bridges and tie-rods;
Overview
The EM sensor adopts a fully waterproof and sealed structure design, which has the advantages of high resolution, strong anti-interference performance, sensitive response to load changes, and good reliability of measurement values. It can work in the open air or in the field. At the same time, after the installation of accessories, the temperature of the measuring point can be measured synchronously, which is convenient for real-time temperature compensation and improves the accuracy and reliability of the monitoring data.
The outer shell of the MAS-CCT-xx EM sensor is made of special steel with high strength and can absorb magnetic flux leakage. When the force value of the measured element passing through the inner shell changes, it can be directly displayed through the supporting acquisition equipment.
The principle of MAS-CCT-xx EM sensor is mainly to calculate the change of cable force by measuring the change of magnetic conductivity of ferromagnetic material, and to set the parameters of the acquisition instrument according to the nature of the material and the parameters of the cable.
Ferromagnetic material (such as stay cable, boom, tie rod, etc.) is magnetized segment in the cable force changes, the magnetic effect, resulting in the change of magnetic permeability, through the acquisition instrument analysis of its change value to reflect the stress change of the component, and finally get the cable force.
Characteristic:
- Non-destructive measurement, no contact with the tested component, no damage to the original component;
- Measuring point temperature can be measured synchronously for real-time temperature compensation;
- High precision, strong anti-interference performance, sensitive to load changes, good repetition;
- Easy to install, durable, can be used for long-term monitoring;
- Low maintenance cost and long applicable life of the sensor;
Application scenarios:
- Anchor cable prestress monitoring;
- Cable force monitoring of arch bridge suspender;
- Cable force monitoring of suspension bridge;
- Cable force monitoring of tie-bar cable-stayed bridge;
