Proper maintenance of equipment to reduce downtime and save money requires more than just replacing parts when they get broken. In fact, replacing a broken part with a new one is an expensive approach for maintaining equipment. To be effective, the maintenance technicians must know why a part has to change and must also have expert knowledge on the use and calibration of a device before installing any device or plant system.
This course is designed to help students to understand the principles of measurement for the proper monitoring and control of their equipment.
On completion of this course, students will have sound knowledge on how to run the plant systems and equipment efficiently and economically.
