Standard Practice for Inductive Wear Debris Sensors in Gearbox and Drivetrain Applications

Standard Details

1.1 This practice covers the minimum requirements for an online inductive sensor system to monitor ferromagnetic and non-ferromagnetic metallic wear debris present in in-service lubricating fluids residing in gearboxes and drivetrains.

1.2 Metallic wear debris considered in this practice can range in size from 40 μm to greater than 1000 μm of equivalent spherical diameter (ESD).

1.3 This practice is suitable for use with the following lubricants: industrial gear oils, petroleum crankcase oils, polyalkylene glycol, polyol esters, and phosphate esters.

1.4 This practice is for metallic wear debris detection, not oil cleanliness.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5.1 Exception—Subsection 7.7 uses “G’s”.
