Magpowr | Advanced Load Cells
Magpowr Load Cells provide the most consistent control of tension through varying conditions allowing for precision and control when it matters most.
TS Load Cells
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. 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.
Global Load Cells
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.
Cantilevered Load Cells
Load cells are not where operators want to spend their money. MAGPOWR’s CL Cantilever Load Cells facilitate that as they are the most cost effective cantilever load cell on the market. These sensors have the unique ability to accept virtually any roll and shaft assembly. 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.
LC-500G Low Tension Load Cells
Lightweight single strand applications including wire, fiber optics and filament textiles face the requirements of tension measurement. For various reasons, lighter, thinner, finer materials are now demanded, and manufacturers require tension controls that can help facilitate those demands. MAGPOWR’s Low Tension Load Cells (LC-500G & LC-500GS1) have full wheatstone bridge strain gage configurations, and the meet the same industry leading specifications as all other MAGPOWR load cells. The LC-500G, designed to mount easily into almost any single strand installation, also employs 360 degrees of overload protection preventing the need for recalibration in the event of overload situations. For applications requiring special pulleys, the LC-500GS1 is available with provisions for a customer-supplied pulley.
TSU Under Pillow Block Load Cells
Ruggedly constructed to stand up to mill duty and with built-in mechanical overload stops in both force directions, MAGPOWR’s TSU Under Pillow Block Load Cells can be bolted under your present roll support bearings and they will accurately measure the tension forces on the machine sensing the roll created by the web. It can display and control the web tension through MAGPOWR tension readouts and controls. The TSU is best used with two load cells, one under each pillow block bearing that supports the sensing roll, which then will accurately measure the total force on the entire roll created by tension in the web, and the readout will be precisely displayed no matter what the position of the web.
TLC Thin Load Cells
The MAGPOWR TLC load cells are extremely accurate devices used to measure web tension in any unwind, rewind or intermediate web processing application. Delivering precise web tension with low temperature drift due to a full Weatstone bridge construction, the load cells allow for force measurement and 10 times overload protection in both force directions.
