Abstract

Disclosed herein are a turbo-machinery blade breakage monitoring unit and a turbo-apparatus having the same. The blade breakage monitoring unit includes a pressure sensor disposed near a rotor having a plurality of blades to be rotated at a predetermined speed, the pressure sensor functioning to measure total pressures of the respective blades. The blade breakage monitoring unit further includes a controller electrically connected to the pressure sensor and functioning to judge whether or not each measured total pressure value, transmitted from the pressure sensor, is within a preset criterion total pressure range. With the use of the blade breakage monitoring unit, total pressures of the respective blades are monitored in real time at a position downstream of the blades when the blades are rotated at a high speed within the turbo-apparatus, such as a turbine, compressor and fan, enabling real-time monitoring of breakage of the blades.
