Operating limits for acoustic measurement of rolling bearing oil film thickness [PDF]
, 2003 An ultrasonic pulse striking a thin layer of liquid trapped between solid bodies will be partially reflected. The proportion reflected is a function of the layer stiffness, which in turn depends on the film thickness and its bulk modulus.
