WEARSCANNER continuously monitors wear particle in oil

WEARSCANNER detects electrically conductive particles in oil using a patented method based on the eddy current principle. Results are independent of oil temperature, flow rate, viscosity, air and water contents or oil color (darkening).


The particles are counted real-time and classified according to their size. Minimum particle detection size is down to 50µm to ensure the detection of the slightest start of detrimental and abnormal wear.

WEARSCANNER identifies ferrite as well as non-ferrite particles. It is ideal for detecting progressive damage to gear teeth or roller bearings at an early stage.

The free of charge WEARSCANNER utility software allows easy configuration of the WEARSCANNER particle counter.

With more than 30 years of experience in the field of eddy current technology and condition monitoring PRÜFTECHNIK joined forces and developed the WEARSCANNER to provide customers another powerful solution to enhance machine availability.
