A multi tip clearance measurement system is provided. The clearance measurement system includes a sensor disposed on a first object, wherein the sensor comprises a plurality of probe tips configured to generate signals representative of a sensed parameter corresponding to a second object and a processing unit configured to evaluate the signals from subsets of the sensed parameters from the probe tips to detect an outlier probe tip and to adjust a gain, or an offset of the respective outlier probe tip for estimating the clearance between the first and second objects based upon the signals.
