pALERT Q332

Feature and Application

Introduction

pALERT Q332 is a cutting-edge tri-axial digital output all-in-one accelerograph. Embedded with a Quartz MEMS (Micro-Electro-Mechanical System) accelerometer, pALERT Q332 convinces with its ultra-low noise, high stability, and ideal power consumption. The Quartz MEMS technology results in high accuracy, durability, and long-term stability that are not achievable with conventional sensor technologies. The versatile pALERT Q332 is well suited to a wide range of challenging applications such as Earthquake Early Warning (EEW), seismic observation, civil engineering vibration monitoring, micro-tremor monitoring for technology plants, as well as Structural Health Monitoring (SHM). The features of pALERT Q332 include a dynamic range of up to 132 dB, a sampling rate of up to 1000 SPS, and support for international standards of intensity scales (MMI, JMA, KMA MMI, CEA, CWB).
