Abstract
A method of improving the measurement accuracy of a digital ice rate sensor by providing an enhanced surface finish on a magnetostrictive oscillator detector probe by measuring the surface roughness of the detector probe, comparing the measured value to a critical value, and authorizing the probe for use in the digital ice rate sensor if surface roughness is within the critical value. Surface roughness may be measured optically or with a surface profilometer. Remedial steps taken if surface roughness is not within the critical value include reworking the probe surface finish and investigating the manufacturing process.
