TS Load Cells
The MAGPOWR TS line of 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 also offer the flexibility of a variety of mounting styles and coupling options.
They are ruggedly constructed with mechanical overload stops in both force directions to eliminate sensor damage and the need to recalibrate even after extreme overloads. A full Wheatstone bridge arrangement of four foil strain gages is used in each sensor for the most accurate means of measuring web tension, reguardless of temperature change. In addition, all sensors incorporate a dual beam construction design to insure linear output under all loading conditions.
Key Features
- Low profile design allows maximum web widths
- Multiple mounting options for maximum flexibility
- Three coupling styles for use with any type idler roll
- Ruggedly constructed for long life and dependability
- Mechanical overload stops for protection even under severe overloads
- Full Wheatstone bridge design for measurement accuracy
- Inch and Metric models for international installations
Load cell mounting styles available
- Stud Mount Load Cell
- Pillow Block Load Cell
- Flange Mount Load Cell
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. As it is shipped from the factory, the coupling is configured to accommodate a dead-shaft installation.
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.
CL Cantilever Load Cells for Narrow Web
The CL Cantilever Load Cells are the most cost effective cantilever load cell on the market. They are designed to support cantilevered idler rolls in processing machines which only have one side frame, and to accurately measure and control tension in a narrow moving web. They are typically used on paper, film, foil, wire, fiber, fabrics or any materials used in the label, tag, tape, printing or converting industry.
A unique advantage of these sensors is their ability to accept your roll and shaft assembly.You are no longer restricted in design - just install one of your own spare roll assemblies into the Model CL Load Cell.Another advantage of these load cells is the capability to be mounted inside or outside of the machine frame.This allows the process rolls to be mounted flush to the machine frame to minimize overhang when the sensor is mounted on the back side of the machine frame.Full Wheatstone bridge provides the best accuracy available.
The model CL Load Cells are ruggedly constructed with built-in mechanical overload stops. A full Wheatstone bridge arrangement is incorporated in each load cell for the most accurate means of measuring web tension. There are 2 sizes available with 5 tension sensing ranges up to 500 lbs.
GTS Under Pillow Block Load Cells
The GTS Global Load Cell is used for under pillow block applications. The units are designed to be mounted under standard inch or metric pillow block bearings, which support a live or dead shaft roll. By measuring the load created by the web and acting on the sensing roll, precise and accurate tension can be displayed and controlled.
Two GTS sensors should be used, one for each side of the sensing roll. When installed in this manner, the two load cells accurately measure 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, since each GTS load cell can be mounted on either side of the machine. Every load cell is constructed with mechanical overload stops in both force directions to prevent load cell damage and eliminate the need for recalibration even after extreme overloads. A full Wheatstone bridge is incorporated into each GTS load cell for the maximum accuracy and stability.
GTS Global load cells are adaptable. All sizes are pre-drilled and tapped to accept standard inch and metric pillow block bearings. Adapter kits are available.
