ABSTRACT:
The invention relates to a method of fabricating a torque sensor to which are applied strain gauges, with the torque sensor being adapted to be coupled between an engine and an absorption dynamometer for use in measuring the torque output of the engine. The subject process results in an integral assembly of two cylindrical rings interconnected by a plurality of elongated bars or beams to which the strain gauges are attached. During the process, a plurality of spaced holes are simultaneously drilled in the two identical, cylindrical rings, after which the rings and beams are assembled such that the rings are disposed in spaced relationship, and with the elongated beams extending between the rings. The beams are connected to the rings by electron beam welding so as to form an integral torque sensor assembly.
