MB Series Tension Sensors Tension ControlAccessories

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.
