By the use of two electric sensors mounted in the casing at the circumference of the rotating blade tips the vibrational deflection of all blades of a blade row can be measured. The system, well established for measurements in model turbines and for testing in steam and gas turbines, is now developed for the continuous observation of the vibrational behavior of all last stage rotating blades of large steam turbines. Operational conditions leading to life-reducing dynamic stresses will thus be identified and can then be avoided. If such operating conditions are unavoidable the remaining service life of each blade is determined continuously and a warning is given before consumption of a blade`s fatigue life, i.e. before crack initiation has been reached.
