WEARSCANNER is an intelligent sensor that detects electrically conductive particles n the medium that passes through it. The sensor counts them in realtime and classifies them according to their size.

WEARSCANNER uses a new patented detection method which is based on the eddy current principle and works independently of oil temperature, flow rate, viscosity, air and water contents or oil color (darkening).

WEARSCANNER benefits

• Recognizes bearing & gear teeth damage
• Avoids consequential damage
• Enhances plant availability

The eddy current measuring principle

An excitation coil (black) that generates an alternating magnetic field (blue) induces eddy currents (green) in the oil. A receiver coil detects the resulting eddy current density. Electrically conductive, i.e. ferritic and non-ferritic contaminants in the oil change the current flow between the excitation and the receiver coils. In order to detect even miniscule particles at high flow velocities WEARSCANNER utilizes the fast reacting differential coils method with two receiver windings connected in opposition.
