Compact Broadband Sensors
EPIC Compact Broadband Sensors:
Features:
Compact broadband seismometers are high-performance, tri-axial sensors designed to measure ground motion across a wide frequency range, from long-period tectonic signals to high-frequency seismic events. Built to deliver robust scientific data in a smaller and lighter form factor, these instruments are ideal for a broad range of seismic monitoring applications, including regional networks, temporary deployments, aftershock studies, and portable field experiments.
Despite their compact size, modern broadband sensors offer excellent dynamic range, low self-noise, and wide bandwidth—routinely covering from tens or hundreds of seconds to over 100 Hz. Housed in rugged enclosures and often designed for direct burial or vault installation, these sensors maintain long-term stability and are suitable for operation in harsh or remote environments.
Key features often include differential velocity outputs, digital or physical leveling aids, integrated calibration capabilities, and compatibility with standard seismic digitizers. With minimal power requirements, these instruments can be paired with low-power acquisition systems, allowing extended deployments in off-grid or battery-powered configurations.
Compact broadband seismometers represent the current state of the art in portable seismic instrumentation, balancing performance, durability, and ease of deployment to meet the demands of both research and operational monitoring networks.
