Data Digger Equipment

Model- DDE120S Broadband Seismograph.

Data Digger Equipments model DDE-120S digital feedback broad band seismometer is based on a truly rectilinear suspension system. Internal 8 channel 24 bit high resolution digitizer utilizes the wide dynamic range of the feedback sensor.Three axis broad band sensor is housed in an ‘O’ ring sealed Hard Anodized water proof Aluminium case. The system is self-contained, except for the power source. Three separate concurrent digital data outputs ports are provided, these being Ethernet, USB and serial RS-232 outputs. External GPS module time synchronizes the digital accelerometer. As a backup NTP time synchronization is available.An isolated wide input range dc-dc converter ensures galvanic isolation of the system and operates from 9 to 36 Volts. The power input is reverse polarity protected including the protection provided by the dc-dc converter. The analogue feedback accelerometer has an extremely large dynamic range and 8 channel 24 bit acquisition system is incorporated to exploit the full dynamic range of the sensor as high gain and low gain digital outputs. The low and high gain outputs are set digitally using the Programmable Gain Amplifiers (PGA) of the 8 channel Acquisition system.
