Description
Version:
Single-handed torque wrenches without a setting scale. Wrench setting using torque analyser.
With reversible ratchet and fixed square drive pin − only for right-hand tightening.
Function:
If the set value is reached while using the wrench, 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 series production.
Standard:
Tested to DIN EN ISO 6789.
Accuracy:
±3% of the set value.
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
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.
