Molecular Electronic recievers of linear oscillatory accelerations

These devices are used for reception and measurement of linear acceleration of small and average level in a mid-frequency range.

They are intended for:

— registration of seismic fluctuations of natural and artificial origin;

— security signal system;

— definition of parameters of movement of objects and location of sea vessels;

— identification systems on dimensions, weight, speed and hydro acoustic characteristics of floating objects for ground and landing mines;

— definition systems of coordinates of falling of head parts of the rockets;

— for definition of coordinates and direction of movement of the low-flying aims in seismic acoustic systems;

— stabilization of platforms on linear acceleration;

— system of seismic control of safety of atomic power stations.

Main advantages:

— measure a linear acceleration in wide dynamic and frequency ranges;

— low level of own noises;

— efficient in the wide range of ambient temperatures;

— small value of cross sensitivity;

— tolerance to environmental pressure change;

— high crashworthiness and vibration strength;

— small energy consumption;

— small period available for operation determined by electronic amplifier;

— small dimensions and weight;

— hermetically sealed;

— fire and explosion safe;

— they do not need care.
