As the need for improved seismic signal quality has increased, the importance of new sensor technology has become clear. Sercel has introduced a new addition to the 408UL system, the Digital Sensor Unit (DSU). The DSU is an integrated package made up of station electronics and a digital accelerometer based on MEMS (Micro-machined Electro-Mechanical Sensor) technology. The DSU offers the same LINK configuration as the current system but with fully integrated digital accelerometers as part of the electronics package. The DSU is available in both three-component or one-component versions.
A link of DSUs can be used in conjunction with 408UL or 428XL systems adding greater capability to these systems. FDUs with analog sensors and DSUs with digital accelerometers can be used within the same spread under control of a single central unit. In addition, the DSU is fully supported by all software functions and telemetry flexibility in the 408UL and 428XL.
The DSU, as all electronics in the 408UL or 428XL, is fully testable. A full set of tests are run by the system automatically all day to ensure an ongoing high quality signal on every shot
Benefits of using DSU3:
1. Field efficiency
2. Better quality P-Waves
3. Access to Converted Waves
