Torque wrench, with a measurement bridge and expansion strip at the wrench head, has a radio interface to transmit torques applied during use as well as actual and nominal value comparisons

摘要

The torque wrench (1) has a head (2) giving a relative movement against the shaft (3). A measurement bridge (10) is at the wrench head, e.g. an expansions trip (11), to register the actual torque. A radio interface (12) transmits to a display (13) at least the actual trip value (Dist), the maximum value (Dmax) measured at the bridge during the use of the torque wrench and the preset nominal trip value (Dsoll).
