FORCE GAUGE The ovality kit is designed principally to measure cylinder liner wear and ovality. However, the device can be modified to take measurements from various applications according to your own requirements. The standard kit contains equipment to measure cylinder liners with diameters of 180­600 mm. The supplied software with the deflection indicator DI­5C also handles the measurements taken with the ovality kit. By this, you can transfer ovality data to your PC and evaluate and compare, all with graphs and printouts.
