摘要： Torque sensing devices, systems, and methods are capable of measuring and/or determining a torque being transmitted through a shaft by measuring the torsional deformation of the shaft over a short length thereof. Such devices, systems, and devices have a sensor positioned adjacent to the outer surface of the shaft as it rotates, the sensor being positioned to maintain a substantially constant distance between the sensor and the outer surface of the shaft. The sensors may be variable reluctance (VR) sensors rigidly attached to a frame mounted on a bearing (e.g., a hanger bearing), which is mounted on the shaft, such that relative radial motion between the shaft and the VR sensor is minimized (e.g., so that they move in unison). Reducing this amount of motion results in a more accurate torque measurement.
