Speed + Position Sensors

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 all in one convenient place. The trainer provides a safe and effective method of demonstrating the operating principles of different types of speed and position sensors that are common on today’s cars and trucks normally used for wheel speed, engine speed and vehicle speed. All sensors are mounted on a common shaft which is driven by a variable speed electric motor to create different operating conditions.

Educational Advantages

  • Turnkey product with complete curriculum
  • Demonstrates full functionality of both analog (passive) and digital (active) speed and position sensors
  • Electronically controlled variable speed drive motor allows sensor operation from zero RPM through both steady and variable speeds
  • Magneto-resistive magnetic strip sensor can detect instant movement of rotation or 0 kph/mph
  • Allows full diagnosis and testing with DVOM and oscilloscope
  • Switches allow the sensor to be disconnected/connected in the circuit for real-world testing purposes.
  • Allows student demonstrations of the operation, diagnosis and testing of:
    • CKP (Crankshaft Position Sensors)
    • CMP (Camshaft Position Sensors)
    • VVT (Variable Valve Timing) sensors
    • ABS Wheel speed sensors (all types)
    • RPM and Vehicle Speed sensors
  • Provides clear visualization of sensors without access limitations of a vehicle

Main Features
