The experimental setup has been developed for laboratory testing of electromechanical energy transducers and rotary magne-torheological (MR) dampers. The design objectives are outlined and the parameters of the key elements of the setup are summarised. The structure of the mechanical and measurement and control systems is presented. Results of functional testing of a newly developed trans-ducer and a MR rotary damper are summarised.

An experimental set-up elaborated for distance measurement with a use of a laser optical displacement sensor has been described. The features of the elaborated device allow to measure a surface roughness and dimensions of small details. Elaborated computer software allows automatically to estimate the classical surface roughness indices. The surface roughness indices can be estimated also for sloping planes. A solidification surface profile in macro and micro scale can also be measured. The mentioned solidification surface profile is measured on solidified shells obtained by using of so-called remove remainder test. Exemplary measurements of mould and casting surface roughness have been presented.
