Accelerometers for monitoring the operation of pulsed seismic sources
ACCELEROMETER ANALOGUE
Designed for use as part of monitoring equipment for the operation of various pulsed sources of excitation of seismic vibrations. The accelerometer generates an output signal proportional to the force on the working elements of the sources during seismic surveys.
In terms of resistance to climatic effects, it corresponds to group 5 according to GOST 22261-82.

ACCELEROMETER DIGITAL
Designed for use as part of monitoring equipment for the operation of various pulsed sources of excitation of seismic vibrations. It differs from an analog device by an interference-proof digital channel for transmitting information to the synchronization system of seismic sources .
In terms of resistance to climatic influences, it corresponds to group 5 according to GOST 22261-82.
