Delta-03 Digital Seismic Signal Recorder
Delta-03 provides automatic registration of seismic signals generated by natural and artificial sources of seismic vibrations
It can be used as permanent seismograph station with the possibility of data logging to a removable high-capacity flash disk and data transmission to PC for real-time analysis and recording
OPERATION MODES
recording upon seismic event detection*
launch to continuous mode or detection mode within specified time intervals (by calendar)
recording upon external-timing reference
* When recording-upon-detection mode is active the digital signaling processor identifies and registers only wanted seismic signals. In addition, the modified algorithm STA/LTA providing multiwindow time-and-frequency analysis is used
CONTROL
It is PC-based via interfaces Ethernet 10/100 and RS-23
SYNCHRONIZATION
by real time clock
reference frequency of real-time clock is generated by precision, high-stable, temperature-stabilized oscillator
real-time clock is set and checked automatically within time points specified by operator using the integral GPS-receiver
or at the command of operator
TELEMETERING NETWORKS
The recorder is designed as a part of telemetering network using the GSM system or satellite modems in the data mode, telephone modems Telemetering networking is possible using the Internet connected via GPRS modems and local networks with the external IP address
SOFTWARE
The recorder control software is compatible with Windows 9x/ME/2000/XP
User-friendly interface provides easy control with the recorder
Graphic applications provide on-line efficient analysis of obtained data
Software makes it possible to use the PC
SPECIFICATIONS
The recorder can be packaged with compatible Lennartz velocimeters: LE-3DLite (1…80Hz); LE-3D/5s (0.2...40Hz);
LE-3D/20s (0.05… 40Hz) or accelerometers: А1632; А0531.
The recorder can be operated with any other types of seismometers.
