Tilia T130 Strong Motion Accelerograph

The Seisodin Tilia T130 is a highly integrated strong motion accelerograph designed for precision seismic monitoring, earthquake recording, structural health monitoring (SHM), and civil infrastructure monitoring applications. The instrument combines a high-performance 3-axis strong motion accelerometer with an integrated seismic recorder, creating a complete solution for capturing and analyzing strong ground motion and structural vibration data.

The T130 delivers ultra-precise measurements using three state-of-the-art force-balance accelerometers (FBA), high-resolution 24-bit digitizers, and advanced timing technology. This combination makes the T130 an ideal seismic sensor for critical monitoring applications where data quality, reliability, and long-term stability are essential.

The Tilia T130 can be daisy-chained using dual Ethernet transceivers integrated directly into the instrument. The system supports distances of up to 100 meters between devices, enabling cost-effective deployment of distributed seismic and structural monitoring networks. An integrated UPS within every instrument ensures continuous recording during power outages and cable breakages, helping to prevent data loss during critical seismic events.

The integrated dual Ethernet transceivers support Power over Ethernet (PoE), allowing each instrument to supply power to the next device in the chain through the Ethernet cable. This significantly reduces installation complexity and infrastructure costs for large monitoring projects.

Tilia accelerographs also provide exceptionally precise timing. The system utilizes hardware-backed phase-locked Precision Time Protocol (PTP) synchronization, achieving industry-leading timing offsets between daisy-chained devices as low as 40 nanoseconds. This level of synchronization is particularly valuable for advanced structural response analysis.
