Wireless acceleration measurement system for confirming vibration isolation performance after the completion of vibration-isolated buildings.
Wireless acceleration measurement on each floor of high-rise buildings.
The Sonas vibration measurement system has been a long-standing supporter as a wireless vibration meter for structural monitoring. It is ideal for earthquake observation in buildings and apartments, as well as for acceleration measurement in structures like bridges. The historical models have a wealth of measurement records in large-scale structures such as skyscrapers and long bridges. 【Features】 - Achieves synchronization between sensors in microsecond units - Compact design the size of a palm - No need for power supply or wiring work, allowing for easy installation - Easy to transport sensors, enabling smooth movement - Battery-operated - Supports remote monitoring and data collection using the cloud - Capable of recording data on an internal memory card
