MECT 2912 - Electro-Hydraulics Technology

Credit Hours: 3.00
(4 contact hrs)
This course teaches the fundamentals of electro-hydraulic systems including components, graphic symbols and basic circuit configurations. Students will calculate the gain for inverting, summing, and current feedback amplifiers. Students will draw the circuits for proportional and servo controls then connect the circuit on a functional hydraulic trainer, wire the appropriate electronic control, tune for optimal response and troubleshoot the system.

Prerequisites:
None
