  Low frequency rotational sensors METR-01 and METR-03 (rotational seismometers)

METR-01

METR-03

The sensors provide new measuring means and data channels in engineering geophysics, exploration seismology, rotational seismic researches, seismic monitoring of high-rise buildings and constructions (bridges, hydroelectric dams and so on), security systems based on the seismic area control and many other applications.

The sensors are very rugged, does not require any maintenance and suited for portable applications and field tests, as well as for permanent installations. The one-component (METR-01) and three-component (METR-03) modifications are available.

  Multicomponent seismic sensors      COLLAPSE <<

 

  Six-component seismic sensor СМЕ-206С

The high-sensitive velocity sensor of the latest design, including 3 orthogonal linear and 3 angular (rotational) sensitivity axes — the unique development based on molecular-electronic technology.

The instrument provides scientists and engineers by new data channels and open new possibilities to retrieve more information from seismic signals. The device combines the advantages of the high-sensitive molecular-electronic linear and angular motion sensors. It is the reliable fast-deploying instrument for field seismic measurements.

Applications: geophysics, exploration seismology, earthquake engineering, seismic monitoring of high-rise buildings, bridges and constructions.
