Abstract: An environmental condition may be measured with a sensor (10) including a wire (20) having an ultrasonic signal transmission characteristic that varies in response to the environmental condition by sensing ultrasonic energy propagated through the wire using multiple types of propagation, and separating an effect of temperature on the wire from an effect of strain on the wire using the sensed ultrasonic energy propagated through the wire using the multiple types of propagation. A positive feedback loop may be used to excite the wire such that strain in the wire is based upon a sensed resonant frequency, while a square wave with a controlled duty cycle may be used to excite the wire at multiple excitation frequencies. A phase matched cone (200, 210) may be used to couple ultrasonic energy between a waveguide wire (202, 212) and a transducer (204, 214).

Abstract: A device and a method for ultrasonic detecting a mechanical member based on magnetic fluid coupling. The device comprises a magnetic field generating apparatus, magnetic fluid and an ultrasonic probe. The magnetic field generating apparatus has a cylindrical structure, into which the magnetic fluid is injected, where an upper portion of the apparatus is provided with the ultrasonic probe a front end that vertically extends into a liquid level of the magnetic fluid, and a bottom portion of the apparatus covers a detected position of a member under detection. The magnetic fluid at least contains magnetic suspension particles and oil-based or water-based liquid. With the device and the method, the ultrasonic probe is coupled with the member under detection to realize ultrasonic detecting of the service stress of the member under detection.

Abstract: A rapid ultrasonic dual-wave calibrated detection method includes: numbering a plurality of high strength bolts; searching, in a database in equipment, a calibrated empirical value R0e of initial ratios R0 of ultrasonic transverse wave transit time to ultrasonic longitudinal wave transit time for bolts with entirely or partially same specification data, or a calibrated empirical value ke of a slope k of variation of a bolt tension with a ratio of transverse wave transit time to longitudinal wave transit time; measuring ratios Ri of the ultrasonic transverse wave transit time to the longitudinal wave transit time for the plurality of high strength bolts; acquiring a pretightening axial force value, and using the pretightening axial force value in place of an average value of tensions of the plurality of high strength bolts, calculating calibrated another parameter ke or R0e; and calculating axial forces of the high strength bolts.

Abstract: A mechanical force measurement system is for measuring a force onto an object. The measurement system includes a sound wave generator which is adapted to generate a solid borne sound wave signal within the object. The system further includes a first sound wave receiver which receives a first solid borne sound wave signal based on the solid borne sound wave signal generated within the object by the sound wave generator. In order to compare a phase of the generated solid borne sound wave signal and a phase of the first received solid borne sound wave signal, and to generate a comparison signal based thereon. The system also includes a comparator unit. An evaluation unit of the system determines the mechanical force based on a data base and the comparison signal. The data base has stored a relation of a mechanical force and a comparison.
