Mechanical calibration device up to 400 N·m No. 7791

7791

measurement possible without moving the point of application of force
thanks to a specially designed force transmission system, mechanical loader No 7791 avoids the risk of the point of force application shifting during the calibration process
the lever below the test rail is actuated in a linear direction by the handwheel acting on a spindle
the linear motion is translated into a rotary movement which acts on the transducer
the torque wrench to be calibrated remains in the same position throughout the calibration process
this prevents measuring errors caused by the point of force application being moved
thanks to a low-friction linear ball bearing, the torque wrench is automatically levelled as it is placed in the unit
a further linear ball bearing ensures the contact with the torque wrench is friction-free
the reduction in lateral forces acting on the transducer and in the friction on the point of contact with the torque wrench results in a corresponding reduction in mismeasurement
