Manual calibration system MANUTORK 7791 up to 400 Nm for torque wrenches - Stahlwille 52110091

Anyone who calibrates and adjusts torque wrenches and torque screwdrivers in their own test lab needs a system that applies the load evenly and without shifting the force application point. The MANUTORK 7791 manual calibration system works up to 400 Nm, accepts transducers of sizes 1-100 and is suitable for wrenches with a functional length Lf of up to 815 mm. According to the manufacturer, it significantly reduces the effort and time required for calibration and adjustment of torque wrenches. Reduced transverse forces on the transducer and friction-free support of the wrench largely prevent measurement errors.

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.
