Sensor technology for directly measuring the stress of rod-shaped steel materials! Long-term monitoring is possible.
The "EM Sensor" is a sensor technology that enables the direct measurement of stress (tension) occurring in rod-shaped steel materials (measured objects) such as cables and strands. It can be installed not only at the fixed end but also at any desired position. It can be installed and measured directly over the coating. Additionally, it has excellent long-term durability, allowing for long-term monitoring. 【Features】 ■ Measures direct stress, not strain ■ Easy to handle ■ Patent number No. 3942463 ■ Registered as a recommended technology for "technologies contributing to the longevity of public civil engineering facilities" in Hiroshima Prefecture, Registration No. 26-005-3 *For more details, please refer to the PDF materials or feel free to contact us.
