摘要
An unbalance detection device for detecting unbalance of a rotor of a turbo-cartridge which includes the rotor including a turbine wheel and a compressor wheel coupled via a rotational shaft and a bearing housing accommodating a bearing which supports the rotor rotatably, includes: a sound pressure sensor capable of detecting vibration upon rotation of the rotor by contactlessly measuring a sound pressure generated from vibration upon rotation of the rotor.
