    Abstract: The proposed force measuring transducer with a frequency output signal comprises an elastic body arranged in a casing in spaced relationship with said casing. The elastic body, which is subjected to the action of a force, has a base and a working member. The base is secured in the casing with the aid of at least three supports. One end of each support is tapered and bears up against the surface of the base, whereas the other end of each support is joined to the casing. The working member is connected to an oscillating element whose oscillation frequency is dependent upon the action of the force. The oscillating member is the resonator of an electromechanical self-excited oscillator.

    Abstract: A strain sensor for determining a strain experienced by a body under test in response to forces exerted on the body-under-test. The strain sensor comprises an interface member mounted on a surface of the body-under-test and a SAW sensor mounted on a surface of the interface member. The strain in the body-under-test is translated to strain in the SAW sensor and determined by the SAW sensor. The strain in the SAW sensor is responsive to the strain in the body-under-test.

    Abstract: A tool may be inserted into the pressure tube inside a calandria tube of a fuel channel of a nuclear reactor. Once in position, the tool may act to generate information useful for determining a location for an annulus spacer. Once the annulus spacer has been located, the tool may act to generate information useful for determining a compressive load on the annulus spacer due to the annulus spacer being pinched between the two tubes. In both the locating and the load determining, the tool may act to isolate a section of the pressure tube, excite the isolated section of the pressure tube with vibrations and measure resultant tube vibrations. Tube vibration characteristics, determined from the vibrations, may then be analyzed to determine an axial location along the pressure tube for the annulus spacer and/or determine a load on the annulus spacer.
