EARTHQUAKE EARLY WARNING SYSTEM

Palert F330 - FBA Seismic Sensor and Recorder

The PALERT-F330 represents Sanlien Technology's debut tri-axial Force Balance Accelerometer (FBA), boasting a remarkable dynamic range exceeding 120dB. Its advanced features, including Pd, PGA, and STA/LTA algorithms, render it an ideal choice for various applications, such as seismic research, onsite and regional earthquake early warning, structural health monitoring (SHM), and rapid structural health diagnostics (RSHD). The device comes equipped with a 10Hz, 20Hz, and 40Hz low-pass filter, which efficiently eliminates non-natural vibration-induced noise.

  • FBA sensors
  • Low Cost
  • Highly Reliable
  • Internationally proven
  • 8 GB system storage

The PALERT-F330 leverages a state-of-the-art 24-bit recorder to enhance CPU processing speed. The FBA's exceptional accuracy and high dynamic range ensure superior performance and resolution compared to MEMS-based devices. Additionally, the device enables seamless continuous recording with the simple press of a button located on its lid.

The PALERT-F330 can serve as a regional array station for mass deployment or operate independently as a standalone device for seismic hazard control. Its embedded Modbus Protocol facilitates user integration with PLC, HMI, or SCADA, and the 3-phase digital outputs (DOs) enable direct control. Overall, the PALERT-F330 presents a cost-effective solution for all strong-motion related applications.

All Products in the PALERT range are independently lab calibrated and certified.
