Filed: 1973-01-16
Abstract: 1362940 Measuring torque electrically INDIKON CO Inc 16 Jan 1973 [31 Jan 1972] 2252/73 Heading G1N In apparatus for measuring the torque transmitted by a shaft 12 (Fig. 1) as determined by the stress produced in strain gauge resistors 20-26 connected in a bridge network 18 and symmetrically mounted on the shaft, the input power and output unbalance signal are fed via rotating coils 30, 32 and a fixed coil 34, and a fixed resistor 96 (Fig. 2) is intermittently added to one arm of the bridge to simulate a known torque in order to calibrate the bridge network. Power for the bridge is obtained from two oscillators 42, 44 alternately connected by switch 40 to coil 34. The induced voltage in winding 32 is rectified and smoothed at 60 to provide power for an oscillator 74 feeding the measuring bridge 18. The signals from oscillators 42, 44 also set and reset a flip-flop 92 which operates a switch 94 to add and remove the fixed resistor 96. Thus the output signals from the bridge, fed through windings 30, 34 and switch 100 to sample and hold circuits 116, 110 represent the torque signal and the torque signal augmented by the fixed unbalance introduced by resistor 96. The ratio of these signals is shown on a meter 124 and is independent of variations in coupling between the coils 30, 32, 34. The resistor 96 may include temperature-sensitive elements which compensate for corresponding variations in the resistance of the bridge strains gauge elements.
