IIAT100 Industrial Instrument Mechanic Level 1

The Industrial Instrumentation Mechanic Level 1 course provides students the opportunity to advance their knowledge and skills acquired either through entry level training or from on the job experience.   The course introduces students to the fundamentals of pressure measurement and its standards and calibration techniques. In addition, students are exposed to conventional panels and recorders, pneumatic relays and special mechanisms. Students study and service process regulators and a wide variety of control valves and actuators.  Students will also undertake an in-depth study of basic electricity including a variety of circuits, switches, relays and solenoids. Students will be exposed to substantial hands-on exercises that will directly relate to the workplace. Upon entering the workforce they will be expected to function as a level one apprentice performing related tasks with structured supervision.
