pALERT F330

Force Balance Accelerometer

pALERT F330 features a high-precision triaxial force-balanced accelerometer to enhance its performance which offers three trigger logics (Pd, PGA, STA/LTA) and filtering options, including high-pass and low-pass filters to reduce non-natural seismic noise.

It incorporates Pd seismic early warning technology, which issues alerts before the arrival of shear waves, reducing earthquake-related disasters. It can estimate S-wave destructiveness when the P-wave displacement exceeds a threshold within 3 seconds.
