Non-contact linear encoder for bridges
Non-contact measurement of bridge expansion and contraction over long distances with high precision.
In the bridge engineering industry, it is important to accurately monitor the expansion and contraction caused by temperature changes and loads in order to maintain the safety and durability of structures. Traditional measurement methods have faced challenges such as site constraints and high maintenance burdens. Our non-contact linear encoders support long-distance measurements and are maintenance-free due to their magnetic design. By accurately grasping the expansion and contraction of bridges and detecting structural anomalies early, we contribute to safety management. 【Application Scenarios】 - Monitoring bridge expansion and contraction - Measuring structural changes due to temperature variations - Aging diagnosis 【Benefits of Implementation】 - Improved safety through non-contact measurement - Reduced maintenance costs - Long-term maintenance of structural integrity
basic information
【Features】 - Measurement possible even in distances/environments where laser measurement cannot reach - Magnetic type, maintenance-free - Measurement distance can be extended infinitely - Maximum gap between scale and reading head is 26mm, track deviation ±10mm - Repeatability ±0.05mm, response speed 10m/sec 【Our Strengths】 Utilizing our original technology of saturable coils, we provide a fundamentally simple magnetic detection element technology that ensures high precision and long-term stability even under adverse conditions. All products are developed and manufactured 100% in Japan, with over 80% of our product lineup being custom-made based on individual customer requests. If you have any issues with sensing or measurement, please feel free to consult us. Our standard products come with a reassuring 3-year warranty.
