Operators are no longer restricted in design – they simply install one of their spare roll assemblies into the Model CL Load Cell.
MAGPOWR’s CL Cantilever Load Cells are designed to support cantilevered idler rolls in processing machines that have just one side frame. They then accurately measure and control tension in a narrow moving web and are typically used on paper, film, foil, wire, fiber, fabrics or any materials used in the label, tag, tape, printing or converting industry.
These rugged load cells have mechanical overload stops and can be mounted inside or outside of the machine frame.
MAGPOWR GTS Load CellsRead More
The stability and accuracy displayed by MAGPOWR’s GTS Global Load Cell allow the tension to be precisely measured and controlled on a roll. The GTS units, designed to be mounted under standard inch or metric pillow block bearings, measure the load created by the web and acting on the sensing roll.
Two GTS Load Cells should be used, one for each side of the sensing roll, thereby accurately measuring the total web tension force acting on the roll, independent of web width or location. The flexible cable connector eliminates the need for left and right models, as each GTS load cell can be mounted on either side of the machine.
A full Wheatstone bridge is incorporated into each GTS load cell for the maximum accuracy and stability. All sizes are adaptable and pre-drilled and tapped to accept standard inch and metric pillow block bearings.
MAGPOWR TS Load CellsRead More
TS Load Cells provide the most consistent control of tension, no matter how the temperature changes throughout the day. In fact, all MAGPOWR Load Cells are designed with foil strain gauges that provide the lowest temperature drift rating possible (.02% per º C), which can mean the difference between a profitable web and a floor of wasted material.
These rugged load cells are extremely accurate devices used to measure tension in any unwind, rewind or intermediate web processing application. The unique low profile design minimizes space requirements inside the machine frames, thus maximizing the potential for web width. TS load cells are designed with mechanical overload stops in both force directions to eliminate sensor damage and the need to recalibrate even after extreme overloads, while also offering the flexibility of a variety of mounting styles and coupling options.
Split coupling models
Load Cells with Split Couplings can be used to measure web tension through dead-shaft or live-shaft idler rolls. With one load cell mounted to each side of the machine frame, the idler roll is supported between the two load cells. The resultant force of the web tension is measured as a load on the roll by the load cells.
The Split Coupling allows the idler roll to be easily installed after the load cells have been mounted to the machine frames. The coupling design also accommodates misalignment between the machine frames and allows for thermal expansion of the idler roll shaft during machine operation. The unique coupling design also allows its use in both dead-shaft and live-shaft applications.
In-roll coupling models
The In-Roll Coupling is designed to insert directly into the end of an idler roll. With one load cell mounted to each side of the machine frame, the idler roll is supported between the two load cells. The resultant force of the web tension is measured as a load on the roll by the load cells.
The In-Roll Coupling includes a spherical bearing to allow for smooth rotation of the idler roll and to accommodate misalignment between the machine frames. This coupling type eliminates the need for idler rolls with shafts and bearings, thus reducing the overall cost of the tension sensing system.
Wire pulley models
The Wire Pulley is used for single strand applications for any kind of material. When mounted to the side of a machine frame or bracket, a load cell measures tension in the strand as it passes over the nickel plated aluminum load cell pulley.
