Abstract
1465734 Measuring torque electrically GENERAL ELECTRIC CO 18 July 1974 [3 Aug 1973] 31858/74 Heading G1N The torque transmitted by a shaft 10 Fig. 1 is determined by measuring the angular displacement between a first pair of teeth 12 and a second pair of teeth 14 attached to an axially displaced location on the shaft 10. As the shaft rotates each tooth 12, 14 induces a pulse in a coil 22 of a shielded pick-up head 20. The pulse train is fed through a filter 26, 28 to a network 30 which converts it to a synchronous square pulse train whose trailing edges trigger a bi-stable multi-vibrator 42 and produce a variable ratio mark/space pulse train whose average value, determined by D.C. filter 62, is proportional to the twist of the shaft 10, and therefore to the shaft torque. The circuit voltage V o is automatically varied with ambient temperature as measured by a thermocouple to compensate for changes in shaft twist with temperature.
