S400 Seismometer

The S-400 seismic sensor (hydraulic fracturing sensor)

3-axis, Wide Bandwidth 4.5-500Hz seismic sensor High Sensitivity 208 V/m/sec. Velocity signal output. Minimum recording signal 1.3nm/sec. Damping 0.57 Borehole Type, up to 100m (Shallow Borehole). Only 50mm diameter Elastic packer mounting. Ideal for Hydraulic Fracturing Recording (Tested) Operating temperature -40 to +200oC Matching with SR24 or SRi32 digitizers / recorders

This type of sensor has been designed for microseismic events recording during hydraulic fracturing reservoir experiments. It uses quad geophone strings per axis, in order to maximize sensitivity and minimize noise level. It is ideal to be paired with our SRi-32 digitizer / recorder.
