CME-6011ND is a digital 3-component low-noise broadband seismometer with a force feedback. A bandwidth of up to 30 sec provides recording of the remote seismic events.
This seismometer combines the low-noise molecular-electronic sensing element (transducer) and the electrodynamic feedback that result in a very flat response over a wide frequency range, a high dynamic range and a greatly improved time and temperature stability of the parameters.
This model is very rugged and does not require any special means or procedures for transportation and installation. The only procedure to start the operation is to place the seismometer on a rigid horizontal surface, turn the power on and wait for several minutes.
This seismometer can be used in various applications including seismic observatories, seismological surveys, seismic microzoning and passive broadband seismic exploration.
