superloadcell 04Comptrol Superloadcells are precision linear displacement transducers especially designed for the measurement and control of web tension on continuous web or strip processing lines. These extremely accurate and reliable mechanical to electrical transducers convert the applied resultant load into a high level electrical output signal directly proportional to the applied tension.

Nine standard models are available with maximum capacity ranges from 50 to 20,000 pounds for pillow block bearing applications. Superloadcells are simple to install and operate making it easy to convert most idler rolls to tension measuring rolls.

Superior accuracy is achieved through the use of the Superloadcell patented C-Flexure Pivot Assembly, which provides frictionless, mechanical deflection. The rugged loadcell structure, designed for overloads of 1000%, is machined from steel, and nickle plated. The C-Flexure is heat treated for durable, maintenance free operation.

Superloadcells can be calibrated to meet the requirements of each application. They may be mounted in any plane around the axis of the roll, and may be operated in either tension or compression - and at any wrap angle. A mechanical zero adjustment at the Superloadcell allows the tare weight (pillow block bearings and the roll) to be zeroed, so that the Superloadcells measure only the force of the strip tension.

superloadcell 03The primary conversion element between the mechanical force and the electrical output is a Dc Linear Variable Differential Transformer (LVDT). The electrical elements of the LVDT are encapsulated and sealed, and are not susceptible to shock, vibration or tampering. LVDTs are provided with reverse voltage protection. Input and output circuits are isolated from each other, and from the chassis. This permits Superloadcells to be used in floating ground or ground return electrical systems.

The output signals from Comptrol Superloadcells may be used to drive analog or digital panel meters and/or used as feedback signals for controlling adjustable speed drives, brakes or clutches for critical tension control. Inherent in the design of the DcLVDT is a zero or null position with absolutely no deadband. The long term stability of the maintenance free LVDT gives the Comptrol Superloadcell operational characteristics and longevity unsurpassed by other loadcells used in similar applications.

This demo displays Comptrol Inc.'s capabilities in the paper, foil, and film industries. Using calculated wrap angles, our tensioncells precisely measure material tension and can adjust spool speeds accordingly. Rolls of material can be monitored to reach a desired weight or diameter via programmable logic controllers. The entire system is controlled by a large, color touchscreen liquid crystal display. Analog tension indicators show material tension at different points along the system, and an anti-static tinsel bar is used to free the material of any electric charge.
