pALERT S303/pALERT Q332 is an advanced version of pALERT network accelerometer. It is reinforced in device protection to IP67, upgrading CUP computing speed, and increasing internal memory for waveform storage.
pALERT S303/pALERT Q332 embeds with Pd technology developed by Prof. Yih-Min Wu of National Taiwan University (NTU). Designed to reduce earthquake damages and by Pd technology, pALERTS303/pALERT Q332 can determine a seismic event within 3 seconds after P waves are first captured and then issue warnings depending on that estimated S waves are devastating or not.
- Provides three triggering algorithms: Pd, PGA, and STA/LTA
- Offers 10Hz, 20Hz and 40Hz low pass filters which are user configurable to filter out high-frequent noise generated by non-seismic vibrations
- Intensity scales for MMI US, KMA Korea, JMA Japan, CWB Taiwan, and CEA China are available for displaying upon users’ configuration
