Even if you are 10,000 km away, you can detect bolt loosening 24 hours a day! Bolt axial force measurement and monitoring system.
Next-generation remote bolt axial force monitoring system, Interbolt. You can know the bolt tightening axial force value in units of 1 kN! It measures the bolt axial force in real-time and automatically sends the data to a cloud server. With this IoT smart technology, you can monitor bolt loosening from anywhere in the cloud. It features an alert notification function that detects and notifies you of bolt loosening, helping to prevent equipment failures during operation. As a result, real-time bolt axial force data can be monitored from anywhere in the world using a computer or smartphone, eliminating the need for operators to be on-site. You can monitor the axial force measurement data from offshore wind power in Hokkaido at an office in Tokyo or even in an office in the United States. Interbolt is equipped with a high-precision bolt load sensor. The battery-operated wireless sensor also includes an LED that allows for easy visual confirmation of the bolt's axial force status. It utilizes LoRa wireless communication, eliminating the need for wiring work. <Remote detection and monitoring of bolt loosening with Interbolt> For inquiries regarding estimates or requests for materials, please contact us.

basic information
The standard axial force measurement accuracy of the Interbolt is ±5%. By implementing the optional calibration, the axial force measurement accuracy can be improved to ±3%. The Interbolt is calibrated against high-precision load standards and comes with a calibration certificate. The bolt tightening axial force value is displayed in units of 1 kN. Additionally, the axial force trend of the bolt is graphed and saved, allowing for long-term monitoring of bolt axial force. It also features a built-in LED indicator that allows you to check the bolt's looseness visually! Workers can easily confirm that the bolts are tightened correctly, even in dark places. The alert notification function detects bolt looseness and notifies you, enabling the prevention of equipment failures during operation. No wiring work is required with wireless operation! Axial force measurement data is obtained from the Interbolt via LoRa wireless communication. Compatible bolt sizes: M16 and above for hex bolts, M30 and above for stud bolts. Compatible bolt strength grades: 4.6 to 12.9 Compatible materials: SS, SC, SCM, SUS, etc. Operating temperature: -40°C to 85°C Dust and water resistance: IP68

Applications/Examples of results
Interbolt has a track record of supplying blade bolts and tower flange bolts for offshore wind power and onshore wind power to Siemens Gamesa, Vestas, and GE. It has also supplied rail joint plate bolts, rail clamps, and train axle counters for the London Underground and New York City Subway. There is a proven record of supplying to railway maintenance machinery manufacturers that maintain tracks. By using accurate bolt axial force values, it is possible to prevent damage to operating equipment in advance. Regular manual inspections become unnecessary, resulting in an "over 80% reduction in costs related to bolt maintenance and upkeep." It is used for monitoring the loosening and axial force of numerous bolts, such as those in bridges.
