摘要： A field device comprising first and second tines; first and second rods coupled to the first and second tines; a coil arrangement fixed to the first rod; a magnet fixed to the second rod, opposite the coil arrangement; excitation circuitry coupled to the coil arrangement and controllable to provide a time-varying current to the coil arrangement, resulting in vibration of the first tine in relation to the second tine; sensing circuitry coupled to the coil arrangement and configured to provide a sensing signal indicative of a change in at least one property of the vibration of the first tine in relation to the second tine; and measurement control circuitry coupled to the excitation circuitry and the sensing circuitry for controlling operation of the excitation circuitry.

摘要： A method of testing a part includes placing a first member on a part to be tested. A second member is placed on an opposed surface of the part. One of the members has an ultrasonic transmitter and the other has an ultrasonic receiver. At least one of the members has at least one magnetic element and the other has at least one of a magnetic element or a ferromagnetic metallic element which is attracted to magnets. One of the members moves along the surface of the part such that magnetic attraction causes the other to move along the opposed surface of the part with the one of the members. A controller (18) causes an ultrasonic signal to be sent from the transmitter through the part to be tested which is received by the receiver and then analyzed by an ultrasonic testing machine.

摘要： The present invention concerns a non-destructive method for measuring a density distribution deviation in a solid object, comprising the steps of: a) providing a first excitation pulse to the solid object, preferably a mechanical impact; b) obtaining a first vibrational response of the solid object to the first excitation pulse, and deriving a first eigenfrequency of a vibrational mode in a first orientation from said first vibrational response; c) providing a second excitation pulse to the solid object, preferably a mechanical impact; d) obtaining a second vibrational response of the solid object to the second excitation pulse, and deriving a second eigenfrequency of said vibrational mode in a second orientation from said second vibrational response, whereby the first excitation pulse is provided to the solid object at a first position and the second excitation pulse is provided to the solid object at a second position which is different from the first position such that the first orientation is different from the second orientation, and whereby the method further comprising the step of: e) comparing the first eigenfrequency with the second frequency, thereby obtaining a measure of the density distribution deviation in said solid object.
