With the launch of the 428XL, the DSU3 has been introduced with enhanced
capabilities to ensure more accurate, higher resolution data. The DSU3 is
an integrated package made up of station electronics and three digital accelerometers
based on MEMS (Micro-machined Electro-Mechanical Sensor) technology with low
power consumption and full functionality at any tilt angle. Thanks to the
new electronics, the DSU3 can be deployed at any tilt angle.
Links of DSU3 can be used in conjunction with 428XL field system. FDUs with analog sensors and DSU3 with digital accelerometers can be used within the same spread under control of a single central unit. In addition, the DSU3 is fully supported by all software functions and telemetry flexibility in the 428XL.
The DSU3, as all electronics in the 400 Series family, is fully testable. A full set of tests are run by the system automatically all day to ensure the highest quality signal on every shot.
Benefits of using DSU3:
o Insensitivity to tilt
o Very low power consumption
o Totally integrated to 428XL field equipment
o Built-in test capability
o Improved reservoir characterization
o Higher resolution image
o Broad band acquisition
o Excellent vector fidelity
