Patent attributes
A torque detection device includes an enclosure, at least one torque-strain bar, at least one adaptor, a coupler, at least one strain gauge, and a torque display unit. The torque-strain bar is enclosed by the enclosure and has opposite ends respectively forming coupling terminals for coupling with the adaptor and the coupler in either direction. The adaptor is connectable to a torque device, such as a hand tool, an electric tool, or a pneumatic tool. The coupler is connectable to a tool piece, such as a wrench socket. The strain gauge is directly mounted to the torque-strain bar to detect the value of a torque applied thereto and to convert the torque value into a torque value signal, which can be outputted in either wired or wireless manner. The torque display unit is mounted to the enclosure and receives the torque value signal from the stain gauge, whereby the torque display unit may perform displaying of torque value, alarming, and storage according to the torque value signal.
