The system is intended for to lead-in outlet signals from 144 seismometers into the computer and to record the information on the printer as well as on a disk for the further processing in another computer.
Technical Characteristics
1. Number of the channel: 144
2. Frequency range of registered oscillation: from 0 to 20 Hz
3. Dynamic range: 80 dB
4. Seismic event registration duration is 1 minute, 5 seconds of before the entry of the first seismic wave
5. Total coefficient of the amplification of the seismic channel: 5x16 = 80 channel is 100, 4x16 = 64 channel is 10
6. The recording of the signals from the seismometer is carried out continuously leaving only the seismic events in the memory of the computer.
7. The absolute time is recorded precisely within 1 s., on condition the computer clock to be corrected every ten day according to the radio signal of the exact time.
8. Time registration on the seismogram is carried out at a step of 0.01, 0.1 and 1s. Of one’s choice.
9. The system has the opportunity to install the demanded low limit of the amplitude of seismic signals, which are to be recorded.
10. The system has the opportunity to change the recorded scale both of the amplitude axle and the time axle.
11. With the presence of the seismic event the system gives light signal on the monitor screen and switches on the relay for illumination of the light-board.
12. Each seismic channel has a graphical and digital record of a seismic event.
13. 2 are applied as seism-recorder for measuring the acceleration and C-069 is applied to measure the oscillation velocity.
14. The system is intended for studying the seismic resistance of a big industrial constructions, atomic power station, dams, etc.
15. The number of the channels can be less than 144, according to the order.
