"MB Series Tension Sensors Tension ControlAccessories nn

The MB Series of load cells uses an LVDT type sensor to converttension into a proportional electrical signal.The LVDT system provides
precise,accurate tension measurement while the mechanical designallows for extremely high overloads without damage to the unit.

Cables Function The LVDT housing also contains a high-frequency oscillator circuit which
guarantees excellent linearity and a
thermal compensating circuit which
ensures zero thermal drift when used
within the stated temperature range. Standard cable (16 ft/5m) provided
with each sensor.Optional cables listed
below,purchased separately. As web tension increases,the resultant
force F (see Figure 1) also increases.This
causes the load plate to rotate minutely
around the pivot point.This pivot point
is a torsion bar which resists the force F.
Due to leverage advantage,actual
sensing roll movement is quite small.
Movement of the core in the LVDT is
proportionately larger,as the core
moves within the LVDT coil,the output
of the coil varies directly with the core
movement,which varies directly with
the force F.The output is thus
proportional to F.The mechanical
structure of the torsion bar and the
mechanical limit stops on the load
plate allow the MB Sensors to survive
100-to-1 overloads without structural
failure or variance in calibration.
