How you'll learn
100% online training on the SEIUM Institute campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetables: students progress at their own pace within the intake period, making it easy to combine with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Parker SensoControl ServiceMaster, Automation Studio, FluidSIM, advanced Excel, in free, academic or evaluation versions. Tests are studied using real procedures for measuring pressures at test points on a machine, flow tests on pumps and valves, and contamination analysis of hydraulic fluid. Assessment is continuous by module, plus the final integrative project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
