IEM offers several patented technologies for detecting flaws in wheels, both visible and internal.  

Key Features and Benefits- Wheel Crack Detection System

- Automatically detect internal flaws and damage: Looks inside the wheel, utilizing ultrasonic wave signals to "see" where a crack or defect is.

- No couplant needed: IEM's self- contained Electromagnetic Acoustic Transduction technology eliminates need for special couplant materials.

- Operate in all temperatures: Temperature and weather have no effect on system performance.

Key Features and Benefits- WiseFlaw Optical Wheel Evaluation

- Non-contact evaluation: Based on non-contact technologies that enable detection of flaws while a train continues its regular operations.

Operates at Range of Speeds:Can operate at any speed from very low to main-line high speeds.

- Able to Detect External Defects: Detects and reports external flaws that have no immediate impact on transit safety, ride quality and fuel efficiency.

- Integration with Wayside Technology: Directly integrates with IEM's current WISE systems.
