发明名称 Transducer for dynamometer
摘要 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.
