The operation is based on
measuring deformation of a resilient element by means of an
RF200 Series displacement
transducer.
As threaded joint is
tightened, the torque is imparted through the wrench body to the
resilient element which carries a square end head. Torsion strain
of the resilient element is converted to linear displacement of the
measuring raster of an optical transducer whose output signals are
processed by a microprocessor module.
The wrench has four control
buttons and a numeric display, where the torque current value on the
wrench is continuously shown.
Minimum and maximum
allowable preset torque values are programmable and stored in the
wrench memory even at de-energization. Data accumulation with
subsequent transmission to PC is possible.
Attainment of preset
tightening torque values can be visually observed on the numeric
display and, also, from light and sound alarm signals.
