Abstract
A measurement system includes a stator-side unit and a rotor-side unit installed on the rotary machine. The stator-side unit includes a stator-side antenna, an oscillation unit that oscillates a microwave signal and outputs the oscillated microwave signal to the stator-side antenna, and a reception unit that demodulates the microwave signal and outputs a desired signal. The rotor-side unit includes a sensor, a rotor-side antenna that receives a microwave transmitted by the stator-side antenna and outputs the microwave signal, a power conversion unit that converts the received microwave signal into predetermined DC power and outputs the DC power, and a modulation unit that modulates a rotor output signal or a multiplication rotor output signal obtained by frequency multiplication of the rotor output signal, according to the output signal of the sensor, using the DC power output of the power conversion unit, and outputs the modulated rotor signal to the rotor-side antenna.
