PCS - Model EHD 2 - Ultra Thin Film Measurement System Brochure

The EHD2 Ultra Thin Film Measurement System is the latest evolution of the successful EHD instrument. It is now a fully automated computer controlled instrument for measuring the film thickness and traction coefficient (friction coefficient) of lubricants in the elastohydrodynamic lubricating regime. The instrument can measure lubricant film thickness down to 1 nm with a precision of +/- 1 nm. The contact pressures and shear rates in this contact are similar to those found in, for example, gears, rolling element bearings and cams. In addition to film thickness measurements, traction coefficients can be measured at any slide/roll ratio from pure rolling up to 100%.
