Assessment 2

Graduates of the Professional Certificate of Competency in Hydraulics and Pneumatics will be able to:

• Explain the concepts related to pressure and flow.
• Describe the construction and operation of hydraulic and pneumatic system components such as actuators and control valves.
• Develop simple circuits for hydraulic and pneumatic applications.
• Examine in detail, the characteristics of hydraulic oil and air.
• Compare proportional and servo technology in regard to electro-hydraulic systems.
• Troubleshoot hydraulic and pneumatic systems.

To obtain a certificate of completion for EIT’s Professional Certificate of Competency course, students must achieve a 65% attendance rate at the live, online weekly webinars.  Detailed summaries or notes can be submitted in lieu of attendance.  In addition, students must obtain an overall 50% marks in the set assessments which are a practical assessment and a proctored exam. Students must obtain a minimum 40% marks in proctored exam to pass this course. Students must also obtain a mark of 100% in weekly quizzes. If a student does not achieve the required score, resubmission/re-attempt opportunity is given only in the practical assessment and the weekly quizzes, not in the exam.

Additional Credit

Upon successful completion of this Professional Certificate of Competency:

• If you apply and are accepted into EIT’s Bachelor of Science (Mechanical Engineering) you will obtain credit for the BME106S Hydraulics and Pneumatics unit.
• If you apply and are accepted into EIT’s 52884WA Advanced Diploma of Mechanical Engineering Technology you can apply for Recognition of Prior Learning towards these two modules: Hydraulics (DMEHYD609) and Pneumatics (DMEPNE610).
