Abstract (en)

[origin: WO2013004951A2] The invention relates to the measurement of blade tip passage times in a turbomachine using a capacitive sensor mounted on a casing in line with the path followed by the tips (80) of the blades of a compressor rotor of the turbomachine. The sensor comprises at least one longilinear electrode (70) fixed to the internal face of the casing and oriented obliquely with respect to the path of the blade tips (80).
