The Right Choice for Strip and Web Tension Applications

STANDARD LOAD CAPACITIES UP TO 35,000 POUNDSComptrol offers standard design configurations for applicationsrequiring from 4 to 35,000 pounds of Maximum Working Force(MWF) per unit. Models are also available to meet higher MWFrequirements. Each unit is factory calibrated to match your tensionrequirements reducing machine startup time.

UP TO 5 VOLT DC OUTPUT DIRECT FROM THE TRANSDUCERWith up to a 5VDC output signal proportional to applied force, there isno need for any additional interface device to amplify the signal. Thesignal magnitude is balanced and electrically isolated, mininizing theeffects of electrical interference.

1000% OVERLOAD PROTECTIONAll Comptrol Tension Transducers aredesigned to withstand up to ten timestheir rated load capacity. This means youdon’t have to buy an oversized device toprovide adequate overload protection.

ZERO TARE ADJUSTMENT MAXIMIZESOUTPUT AT FULL LOADComptrol Superloadcells and Monocellshave the ability to mechanically or electri-cally “Zero the Tare” up to 2 times therated MWF of the Transducer withoutaffecting resolution.
