Early detection of abnormalities in infrastructure equipment. High-sensitivity, wide-band wire sensors.
In the infrastructure industry, it is important to detect equipment deterioration due to aging and environmental changes early to prevent accidents and long-term shutdowns. Structures such as bridges, tunnels, piping, and plant equipment are susceptible to aging, vibration loads, temperature changes, and external forces, and visual inspections alone may miss early signs of abnormalities. The PICLIA piezoelectric wire sensor, with its thin and flexible wire shape like a thread, can be easily installed on curved surfaces, narrow spaces, and around existing equipment, allowing it to sensitively capture changes in equipment vibrations, distortions, contact, and impacts. This contributes to the condition monitoring of infrastructure equipment, the detection of abnormal signs, and the optimization of maintenance plans. 【Usage Scenarios】 - Detection of leaks, blockages, and abnormal vibrations in piping and ducts Captures changes in vibration and contact sounds due to fluid anomalies, aiding in the early detection of water leaks, leaks, accumulation, and blockages. - Continuous condition monitoring of plant equipment Monitors operational vibrations of pumps, motors, valves, compressors, etc., to identify signs of loosening, wear, misalignment, and abnormal sounds. - Retrofitting sensing to existing structures Easily installed on equipment where drilling or major modifications are difficult, utilizing its ability to follow curved surfaces, enhancing monitoring of existing equipment. - Detection of abnormalities in tunnel inner walls and linings.
