Abstract: The measuring element for a dynamometer consists of a band-shaped substrate of amorphous metal. The band-shaped substrate has one or two necked-down sections on which strain gauge resistors are arranged in the direction of load application. The resistor or resistors may be connected in a bridge circuit together with reference resistors. The load-dependent elongation of the resistors unbalances the bridge circuit to create the desired output measuring signal. Use of a suitable alloy of amorphous metal results in good mechanical characteristic of the measuring element. Specifically, there is a high resistance to creep and to hysteresis effects, while relatively high loads may be measured. Further, such a measuring element is also immune to temperature variations.

Abstract: The transducing apparatus for a dynamometer includes a band shaped measuring element which is subjected to a load-dependent tensile force. The measuring element is made of an amorphous metal. It is band-shaped and may have one or two necked-down portions whose resistance varies as a function of applied force. Such measuring element has particularly desirable mechanical characteristics such as high limits of permissible applied force, resistance to creep, low hysteresis, and stability with respect to temperature variations.
