Abstract: The inventive force measuring cell consists of a plate (2) which is provided with a circular hole (2), the axis of which is perpendicular to the surface of said plate (2) and to the direction of the force that is to be measured. Said axis also lies within the neutral surface of the plate (2). The plate (2) can also be the web of a carrier. A measuring transducer (12) is inserted into the hole (3) in order to measure any modification of the size of the diameter of said hole (3) on a plane that is inclined at an angle of 45 DEG counter to the direction of the force (F) to be measured. A lateral force is created in the direction of y in addition to a transverse stress tau with a component tau xy by applying force in the direction of y when at least one side of the plate (2) is clamped in the base. The originally circular hole (3) is deformed into an ellipse. The measuring transducer (12) consists of a measuring transformer with an oscillating string.

Abstract: A double-ended tuning fork (DETF) is formed from two vibrating beams joined together at each end, having a thickness t, a width w, a length L and a vibrating beam length m. The dimensional ratios t/w and L/m for the DETF are selected according to a relatively more accurate spurious mode map based upon detailled finite element calculations at specific dimensional ratios for t/w and L/m. The results of the finite element analysis are fit by way of a least-squared polynominal over the entire dimensional range of interest. The results of the finite element analysis for the spurious modes provide differences of up to fourteen percent (14 %) relative to the spurious mode map based on simple beam theory. In addition, the spurious mode map in accordance with the present invention accounts for the use of symmetric in the base region outriggers in the base region of the DETF which increases the mechanical Q of the DETF.

Abstract: In a load cell for a weighing machine, the load cell includes a vibrating beam force sensor clamped at its two ends to respective support parts of the load cell, and wherein each end of the sensor is clamped by a bolt having a head which traps the associated end of the sensor against a support part, the bolt having remote from its head a threaded portion engaged with a nut which tensions the bolt, and a portion of non-circular cross section having at least one cross sectional dimension which is greater than that of the threaded portion, the non-circular cross section portion of the bolt having been drawn through a hole in the support part which had a diameter less than said one cross sectional dimension. This reduces the production of forces parallel to the plane in which clamping is required.

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).
