7706-11PC - Test station for torque wrenches in the range of 20-3000 Nm, 96521074

Measurement possible without shifting the point of force application.
Thanks to a specially designed force transmission system, the No. 7791 mechanical loader avoids the risk of shifting the point of force application during the calibration process
the lever under the test rail is driven 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
another 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
