摘要： Measurement of bladed rotors and, more particularly, speed measurement of bladed rotors in a turbine engine using microwave probes is described. In one embodiment, an apparatus for measuring bladed includes a microwave sensor that radiates a microwave signal toward a bladed rotor and receives a reflected microwave signal from the bladed rotor, a radio frequency module that generates the microwave signal radiated by the microwave sensor and down-converts the reflected microwave signal into a down-converted signal, and a main processing module configured to generate an output pulse train signal representative of a speed of the bladed rotor based on the down-converted signal. In another embodiment, a method for measuring bladed rotors is described including radiating a microwave signal, receiving a reflected microwave signal, down-converting the reflected microwave signal, and generating an output pulse train signal representative of a speed of a bladed rotor based on the down-converted signal.

摘要： A temperature measurement technique for calculating a temperature in a high temperature environment by monitoring a change in resonant frequency of a resonant structure loaded with a dielectric material. A response curve for a reflection coefficient S11 associated with the resonant structure is generated, typically by the use of a network analyzer connected to the resonant structure via a cable. A minimum point for the response curve is identified to detect the resonant frequency for the resonant structure. A calibration map is applied to the minimum point to identify a temperature associated with the resonant frequency of the resonant structure. The temperature associated with the resonant frequency of the resonant structure represents the temperature of the high temperature environment.

摘要： A method is proposed for actuating an electromagnetic load (3) which can be switched between at least two switching states, particularly a magnetic valve, wherein switching between a first and a second of the switching states takes place as a result of a current flowing through the load (3) by means of applying an electrical voltage to said load (3). Provision is thereby made for the voltage to be clocked upon application thereof to said load (3) if due to the applied voltage the switching process would occur without clocking outside of a current ramp-up. The invention furthermore relates to an electrical circuit for actuating an electromagnetic load (3).
