The GB6211 seismometers combine the low-noise molecular-electronic sensing element (transducer) and the electrodynamic feedback which results in a very flat response over a wide frequency range, high dynamic range and greatly improved time and temperature stability of the instrument parameters.
Like other molecularelectronic instruments, the GB6211 seismometer 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 the rigid horizontal surface, turn the power on and wait for several minutes.
The seismometer can be used in various areas including permanent stations and field experiments. The sensing element of a MET transducer consists of two hermetically sealed filled with electrolyte housings connected by a channel with electrodes across.
The electrodes are separated by perforated dielectric spacers. The electrolyte plays the role of the inertial mass, while hydrodynamic impedance of the sensing element acts as the damping mechanism providing a feedback for stabilization of the transfer function.
