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. It measures bolt axial force in real-time with a precision of 1 kN and automatically sends the data to a cloud server. This IoT smart technology allows monitoring of bolt loosening from anywhere in the cloud. 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. Axial force measurement data from offshore wind power in Hokkaido can be monitored in an office in Tokyo or even in an office in the United States. InterBolt is equipped with high-precision bolt load sensors. The battery-operated wireless sensor also includes an LED indicator that allows easy color-coded verification of the bolt's axial force status. Data can be sent to the InterBolt gateway for remote monitoring in the cloud or monitored on-site using the InterBolt tablet. It utilizes LoRa wireless communication, eliminating the need for wiring work. <About the bolt axial force monitoring InterBolt> For inquiries such as requests for quotes or materials, please contact us.

basic information
The standard axial force measurement accuracy of the Interbolt is ±5%. By implementing the additional calibration option, 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. It also features a built-in LED indicator that allows for easy color verification of the bolt's axial force status. During the tightening process, the axial force value of the bolt is measured and displayed in real-time in 1 kN increments, enabling the operator to confirm that the bolt is being tightened correctly. With the alert and notification function, customers can be notified if the bolt's axial force value exceeds the set axial force range. This allows for prompt preventive maintenance and helps prevent equipment failure during operation. Compatible bolt sizes: M16 or larger for hex bolts, M30 or larger 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
