Version:
Single-handed torque wrench without a setting scale. Wrench setting using torque analyser.
Left-hand tightening by reversing the plug-in head.Without plug-in head (base model); see No.
657582 −
657590 for suitable plug-in heads.
Function:
On reaching the set torque value the wrench triggers giving a “signal”(audible and perceptible) and is then immediately ready for use again.
Application:
For controlled screw tightening etc. to specified torques in batch productions.
Standard:
Tested to DIN EN ISO 6789.
Cutting data:
Legend for drawing and formula:
l1 = Lever length without plug-in head
l2 = Adjusted reference dimension on the torque wrench
l3 = Lever length including factory calibration reference dimension
l4 = Reference dimension of the plug-in head
L = Total length of the tool
T1 = Torque to be set
T2 = Specified torque
Note:
The guaranteed measuring accuracy of the torque is achieved only once the torque range has been calibrated to DIN EN ISO 6789.
