Abstract
A rotary power tool including a gear case, an output shaft extending from the gear case, and a drive mechanism configured to provide torque to the output shaft, causing the output shaft to rotate. The rotary power tool further includes a clutch mechanism between the output shaft and the drive mechanism. The clutch mechanism includes a compression spring and is configured to limit the amount of torque provided by the output shaft. The rotary power tool further includes a sensor positioned on a neck portion of the gear case subject to strain imparted by the compression spring, and an electronic control unit configured to receive an output signal from the strain gauge and determine a torque setting of the clutch mechanism based on the output signal.
