Measurement without displacement of the force application point
Thanks to a special force transmission system, the mechanical calibration device No. 7791 prevents displacement of the force application point during the calibration process.
Driven by a handwheel, the lever mounted under the test rail moves linearly via a spindle.
The linear motion is converted into rotational motion, which acts on the transducer.
The torque wrench intended for calibration remains in a fixed position throughout the entire calibration process.
This prevents measurement errors resulting from a shift in the point of force application.
The torque wrench is automatically aligned horizontally using a low-friction ball bushing.
An additional ball bushing provides frictionless support for the torque wrench.
The resulting reduction in lateral forces acting on the transducer and friction on the torque wrench support leads to a reduction in measurement errors.

• For Mechanical Drive No. 7791

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

with one pair of adapter plates No. 7770-3 to compensate for the height difference between extension unit No. 7791-1 and perfectControl® calibration units No. 7794-1 and No. 7794-2
