7791 - Mechanical torque wrench, 1 to 400 Nm, 52110091

measurement possible without shifting the point of force application.
thanks to a specially designed force transmission system, the mechanical loader No. 7791 avoids the risk of shifting the force application point during the calibration process
the lever under the test rail is actuated in a linear direction by a handwheel acting on the spindle
the linear motion is converted into rotational motion, which acts on the transducer
The torque wrench used for calibration remains in the same position throughout the entire calibration process, which prevents
measurement errors caused by a shift in the point of force application thanks to
a low-friction linear ball bearing; the torque wrench
is automatically leveled when placed in the device
an additional linear ball bearing ensures frictionless contact with the torque wrench
reducing the lateral forces acting on the transducer and friction at the point of contact with the torque wrench results in a corresponding reduction in measurement errors
