Abstract

In this work the development of a custom submarine data acquisition system for the measurement of ship propeller strain is presented. The system measures the strain applied to 120 Ohm quarter bridge strain gauge sensors. It supports up to 15 acquisition channels, each with its own sensor, signal conditioning and 10-bit A/D converter, sampled at 500 Hz. The system features all necessary analog and digital subsystems needed to perform the signal conditioning, acquisition and data storage. The main features of the system include low power consumption using sophisticated power management, compact design based on a multi-processor architecture, high measurement accuracy, low-cost and robust autonomous operation. The system can be easily extended for applications where a telemetry system with stand-alone operation is needed.
