Products Catalog: Measurement of blade-tip clearance on turbines and compressors

(Product Photo) Measurement of blade-tip clearance on turbines and compressors. Knowledge of the blade-tip clearance under different operating conditions is important for the optimization of efficiency and functional reliability. The clearance is acquired with a non-contacting displacement sensor which measures the distance to the blade tips from the housing. The arduous ambient conditions, the shape of the blade and the extremely short dwell period of the blade in the acquisition range represent high demands on the sensor. With extremely fast rotating turbines the step response of the demodulator electronic unit can be further improved by a special option (signal decay time 1.5 ¼s). A integral peak-peak detector in the controller saves the minimum value of the output signal each revolution, which corresponds to the smallest tip clearance and is important for monitoring. A following limit switch provides advance warning or safety switching in case of risk of damage.
