Course Description
This lab provides and opportunity to work with instruments and control hardware found aboard ship and in industry, and supplements the content of EN‑3216. Students will select, install, and calibrate various sensors and instruments; build and tune PID control loops; design and implement control circuits using Programmable Logic Controllers and Ladder Logic.
This course consists of Twelve 2-hour laboratories and a project or report.
Entrance requirements
Concurrent attendance or successful completion of EN‑3216.
