    Abstract: In one aspect, a load cell includes an elastic body, first optical unit, second optical unit, detector, and computation unit. The first optical unit has a light source, a first diffraction grating on which light from the light source is incident, and a light-receiving unit. The first optical unit is fixed to a first end portion of the elastic body and arranged within a hollow portion of the elastic body. The second optical unit has a second diffraction grating on which diffracted light from the first diffraction grating is incident to generate interference light. The second optical unit is fixed to a second end portion of the elastic body and arranged within the hollow portion. The detector detects the interference light. The computation unit computes a relative displacement amount of the second diffraction grating relative to the first diffraction grating on the basis of a signal obtained by the detector.

    Abstract: A non-contact, current sensor includes a gapped magnetic core configured to circumscribe a current carrying conductor. A magnetostrictive element is mechanically coupled to the gapped magnetic core. Current flowing in the current carrying conductor induces a magnetic field in the magnetic core that flows through the magnetostrictive element. The gapped magnetic core is provided with mounting sections to which the magnetostrictive element is mechanically coupled. The mounting sections have a geometry that increases magnetic flux in the magnetostrictive element. A strain gauge is mechanically coupled to the magnetostrictive element to measure displacement in the element induced by the magnetic flux.

    Abstract: A dynamic mechanical analyzer and a sample fixture for a dynamic mechanical analyzer that attaches fixed clamps in the sample fixture to a rigid frame using mounts that are compliant in the direction perpendicular to the sample displacement but which at the same time are resistant to rotation about the transverse direction of the sample. The compliant mounts include a pair of flexures that are attached to each fixed clamp and to the frame of the sample fixture. In an embodiment, the pair of flexures are thin flat members such that each pair constitutes two parallel leaf springs. The flexures flex to allow the fixed clamps to move perpendicularly to the sample displacement, but at the same time prevent rotation of the fixed clamps.
