  • Contactless device for measuring operating parameters of rotors of high-speed rotary machines
    Patent number: 8256954
    Abstract: A contactless device for measuring at least the temperature of a rotor of a high-speed rotary machine, in particular a turbomolecular vacuum pump, comprises at least one magnetic capsule mounted on the rotor of the pump. The capsule comprises a permanent magnet and at least one pastille of ferromagnetic material having a Curie temperature slightly higher than a maximum temperature to be measured. The magnetic permeability of this material strongly depends on temperature. The pastille is intended to alter the magnetic field generated by the magnet. A detector carried by the stator of the pump generates pulses representative of the magnetic field varying with the rotor temperature, generated by the capsule, whenever the latter passes in front of the detector.
