Measurement of film thickness in the EHL (Elastohydrodynamic Lubrication) field [EHD Film Thickness Tester]
The oil film thickness in the elastic fluid lubrication state is measured using the principle of optical interference.
【Product Overview】 The EHD Oil Film Thickness Tester is a tabletop fully automatic oil film thickness testing machine provided by PCS Instruments in the UK, and it is the successor model to the already proven EHD1. 【Features】 It is capable of measuring thinner films (minimum oil film thickness of 2nm) than conventional optical interference methods. By using the optional 3D-SLIM, it is possible to analyze the oil film thickness distribution across the entire contact area. 【Main Evaluation Contents】 Oil film thickness Stribeck curve (friction coefficient × rolling speed) Traction curve (friction coefficient × slip ratio) Oil film thickness distribution *Optional
