Since a gas turbine is hot engine, its bearing vibration measurement cannot be done through an eddy probe system. Generally a velocity or an acceleration pick-up is used for measuring and monitoring the vibration on the body of the gas turbine. The vibration pick-ups are generally installed on the turbine’s CT/GP and PT points.
