Abstract
An apparatus for detecting and measuring torque applied about the central longitudinal axis of the apparatus including a torque receiving frame which may be attached to a device for which torque is to be monitored, a plurality of strain gauges mounted on selected portions of the torque receiving frame for monitoring longitudinal strain therein, a signal processing device for selectively comparing longitudinal strain signals provided by the strain gauges for determining the magnitude and direction of torque applied to the apparatus, a data logging device mounted within the apparatus for collecting and storing data indicative of torque experienced by the apparatus, and a display device connectable to the data logging device for displaying the data stored by the data logging device.
