Description

Technology
Sensors of type ASC EQ-3211 are based on proven MEMS technology and a capacitive operating principle. The integrated electronics provide a differential analog voltage output (±2.7 V FSO) and accept a flexible supply voltage from 5 to 40 VDC. The ASC EQ series delivers ultra-low noise and a resolution < 1 µg, meeting seismic motion class B requirements. An integrated built-in self-test allows on-site verification of sensor functionality.

Housing
The accelerometers are housed in a lightweight, corrosion-resistant aluminum enclosure rated IP67. A detachable cable with configurable length and choice of connectors simplifies installation and maintenance.

Applications
Designed for continuous monitoring of safety-critical structures such as power plants, tunnels and other civil infrastructure, the ASC EQ-3211 reliably detects very small vibration amplitudes for structural health monitoring and seismic instrumentation.
