Pistons

Combustion engines must withstand maximum loads during a long service life. In order to deal with this requirement, eddy current sensors from the eddyNCDT series are installed in the engine for many different measurements. As the smallest eddy current sensors in the world, these sensors can be used in the fuelled condition. Examples of measurement already being carried out are: valve lift, needle lift, breathing of the cylinder head, lubrication gap on the cylinder, oil film thickness, crankshaft concentricity, crankshaft axial movement and piston secondary movement
