APPLICATIONS
- Local, regional and teleseismic monitoring
- National seismic networks
- Permanent volcano monitoring networks
- Long-term microseismic monitoring
- Rapid temporary deployments, e.g. aftershock and volcanic unrest monitoring
A truly portable, broadband, weak-motion triaxial seismometer
The Güralp 3ESPC is a proven weak-motion triaxial broadband seismometer for the price and size of a medium-motion instrument.
Ideally suited for long-term temporary and permanent installations in areas with low to moderate noise levels. The instruments' broadband response and low self-noise level make it suitable for seismic monitoring at all scales: local, regional and teleseismic.
A low-power and portable instrument for areas with low to moderate noise
-
- 60 s - 100 Hz standard frequency response, (option of 120 s low-pass corner)
- Covers the complete seismic spectrum with a single transfer function
- Self noise below the USGS NLNM from 30 s to 10 Hz
- High linearity: > 107 dB horizontal, 111 dB vertical
- Over 165 dB dynamic range over a wide frequency band
- Cross axis rejection over 62 dB; sensor axes orthogonal to within ± 0.05°
- Robust automatic mass locking, unlocking and centring
- Low power consumption of just 750 mW
- Truly portable - just 8.4 kg with lifing handle, and convenient access to connectors
- Hard anodised aluminium enclosure
- IP68 - protection against effects of prolonged immersion at 3 m depth for 72 hours
