THIẾT BỊ HIỆU CHUẨN CƠ KHÍ 400N.m STAHLWILLE 7791 52110091

Mechanical calibration device up to 400 N·m No. 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
• protected by national and international patents
