Health indicator metrics applicable to inductive wear debris sensors

Abstract: The Inductive Wear Debris Sensor is a relatively new invention that is increasingly being used for the detection of incipient machinery damage or failures by sensing metallic debris in lubrication systems. This type of sensor is typically used in-line and has a superior particle size detection range compared to traditional techniques such as the ubiquitous spectrometric oil analysis. There is, however, very little in the literature regarding the application and interpretation of data arising from this type of … Show more

“…However, gears are often subjected to high torques and cyclic loads, which eventually lead to component failures due to fatigue. Gearbox health monitoring is conducted using a variety of methods including wear debris monitoring [ 1 , 2 ], thermography [ 3 ] and vibration analysis [ 4 , 5 , 6 ]. It is common to combine more than one method, e.g., wear debris and vibration trending, to provide a better indication of health through a hybrid model [ 7 ].…”

“…• Calculate vector f (1) : New filter coefficient defined as with the correlation between y 3 (t) and the data d(t). f (1) is found by solving the system Rg = f ; where R is a N×N autocorrelation matrix defined with the N first delay of the autocorrelation function of the data d(t).…”

“…Inductance detection could differentiate between ferrous and nonferrous debris [11,12], and it is insensitive to air bubbles and water droplets [13,14]. Some inductive sensors, such as MetalSCAN (an on-line oil debris sensor made by GasTOPs Ltd. ), have been utilized in the wind turbine gearbox and aviation machinery [15,16,17,18]. Similar to other sensors, the sensitivity is an important feature for the inductive sensor.…”
