Manual calibration system 7706-9PC 2-100 Nm for torque wrenches - Stahlwille 96521069

When calibrating torque wrenches, the way the load is applied determines the measuring accuracy: if the force application point shifts or transverse forces act on the transducer, the result deviates. The 7706-9PC manual calibration system from the 7706 series covers a torque range of 2-100 Nm. Torque is applied via a handwheel that moves a lever linearly through a spindle and thus transmits a rotary movement to the transducer. The wrench remains in position throughout.

Benefits

• Special force transmission system prevents the force application point from shifting during calibration
• The handwheel drives a lever linearly via a spindle, and this movement is converted into a rotary movement for the transducer
• 2 ball-bearing bushings ensure a friction-free contact surface and enable horizontal alignment of the wrench
• The torque wrench remains in position while the load is being applied
• Minimal transverse forces and reduced friction minimise measurement errors
• Protected by national and international patents

Applications

Quality control and test equipment monitoring: calibrating and adjusting torque wrenches in the test lab, in the workshop and in production.
