Wire drawing machinery
Haehne has developed a sensor specifically for the direct
measurement of small and medium web tension forces,
ranging from 25 to 1,000 Newtons, acting in cables, wires, ropes
and tapes. They can be used in cable making and stranding
machines that already require deflection rolls or pulleys.
The sensors have been optimised with finite element analysis
methods (FMA) and have a series of special features:
The total nominal force range from 25 to 1,000 Newtons is •
covered by one mechanical size
Both clamping block and flange mounting versions, •
several cable connections and quick disconnects are
available
Mechanical stops provide six-fold overload protection •
Adaptation to various mounting elements using different •
axle adapters
Zero adjust by an externally accessible potentiometer •
Strain gauges applied to the active surface of the cantilever
bending beam measure the acting forces. The integrated strain
gauge amplifier converts the bridge signals into a standardised
current output signal of 4 to 20 milliamps.
The signal can be used, for instance, for displaying the force or
as actual value in closed loop controls.
The power supply is 24 volts DC.
