摘要： A torque-angle wrench is provided with a handle for applying torque, such as to a fastener or bolt, through a tightening angle, at a rotational angular velocity. A piezoelectric gyroscopic sensor device including circuitry for vibrating an oscillating body is coupled to the wrench. As the wrench is rotated through the tightening angle, its rotational angular velocity causes the vibrating body to alter its direction of vibration. The new vibrating pattern is sensed and converted, by appropriate sensing circuitry, into an electrical signal proportional in intensity to the rotational angular velocity of the wrench. The electrical signal can be electronically processed by appropriate conversion and display circuitry to provide a visual indication of the tightening angle. Such conversion and display circuitry can be integral with the wrench or as part of an adaptably coupled meter non-integrally connected to the sensor device.
