Tip-Timing

Tip-Timing or blade deformation measurement is applied to turbines and the use of fibre optic sensors provides a fast and reliable alternative to strain gauge instrumentation for measuring dynamic stresses on turbine blades.

In the Aerospace, Energy or Research Laboratory, 152M sensors accurately determine the passage of the blade at a particular location and do not, in some cases, require the use of multiple sensors.

The fiber optic sensors have the following advantages over other sensors used for this purpose: provision of a dual "TTL & Analogue" signal, insensitivity to electromagnetic interference, reduced weight and size, high sensitivity, resolution and bandwidth.
