High-Resolution Depth Counter

Overview

The high resolution depth counter (HRDC) is a modular, rack-mounted panel developed to improve the standard depth measurement capability offered by conventional shipboard and truck mounted logging winches. The HRDC became a nessessity as third party logging tools with improved measurement resolution became available. The system was designed and manufactured in-house and is currently installed in the shipboard data acquisition system. The HRDC presently interfaces with an industrial PC though a serial connection and its operation is virtually transparent to the operator. The HRDC is available to all other third party logging tools. ASCII data files can be generated with depth vs time as output or streaming data can be provided as well.
