As several techniques for diagnostics and condition-based maintenance have been developed over the years, the tip-timing approach is one of the preferred approaches for characterizing the dynamic behavior of turbine blades using non-contact probes. This experimental work investigates the uncertainty of the time-of-arrival of a Blade Tip-Timing measurement system, a fundamental requirement for numerical and aeromechanical modeling validation. The study is applied to both the measurement setup and the data processing procedure of a generic commercial measurement system. The influence of electronic components and signal processing on the tip-timing uncertainty is determined under different operating conditions.<\/jats:p>","DOI":"10.3390\/s23031129","type":"journal-article","created":{"date-parts":[[2023,1,19]],"date-time":"2023-01-19T06:33:51Z","timestamp":1674110031000},"page":"1129","source":"Crossref","is-referenced-by-count":7,"title":["Experimental Investigation on Hardware and Triggering Effect in Tip-Timing Measurement Uncertainty"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1333-9930","authenticated-orcid":false,"given":"Lorenzo","family":"Capponi","sequence":"first","affiliation":[{"name":"Department of Engineering, University of Perugia, Via G.
