ABSTRACT:
A tongs having gripping jaws and a handle for applying an actuating force thereto is characterized by a sensing unit mounted in a force-receiving relationship with the handle. The sensing unit is responsive to a compression or tension force imposed thereon when an actuating force is applied to the handle to generate a signal functionally related to the magnitude of the actuating force. A readout device may be connected to the sensing unit and responsive to the signal generated therefrom to provide a visual indication in any predetermined units of the magnitude of the force imposed on the handle or the torque imposed by the jaws resulting therefrom.
