The EM-200-25 Speed and Position Sensors trainer is used to demonstrate the operation, diagnosis and testing of common types of analog and digital speed and position sensors as they operate on a real vehicle. The trainer includes Inductive, Hall-Effect and Magneto-resistive sensors. All sensors are driven by a variable speed electric motor to create different operating conditions. The trainer provides a safe and effective method of demonstrating the operating principles of different types of speed and position sensors used on today’s vehicles.
