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.
MAGPOWR PS-24 and PS-90 Power Supply for Clutches and BrakesRead More
Complete control is the goal of any operation utilizing brakes and clutches. MAGPOWR’s PS-24 & PS-90 Power Supplies provide a small amount of reverse current circuitry as a standard feature to minimize the drag torque of a clutch/brake, allowing greater controllability in the lowest torque range.
These power supply units control any size MAGPOWR clutch or brake with optimum resolution. MAGPOWR’s current-regulated power supplies are used for the control of magnetic particle clutches and brakes in unwind, rewind, or intermediate tension control applications. With selectable current ranges, these compact enclosures can be mounted inside the machine cabinet, allowing your operator to adjust torque through a remotely mounted potentiometer or with a 0 to 10 vdc control signal from MAGPOWR Open Loop and Closed Loop controllers, or any control device like a computer or PLC.
MAGPOWR TC-5 Power Supply for Clutches and BrakesRead More
Dependable current-regulated power supplies are imperative for the proper operation of all magnetic particle clutches and brakes, and MAGPOWR’s are no different. The MAGPOWR TC-5 is a solid state current regulated 90 VDC power supply. It has four current ranges of 1/8, 1/4, 1/2 and 1 amp, selected by a simple jumper on the circuit board. This unit also includes reverse current circuitry as a standard feature, thus allowing greater controllability in the lowest torque range of the clutch or brake being operated. The TC-5 is easy to work with, as the front panel meter indicates the current output and automatically reads full scale for each current range selected. The operator controls the output by rotating the front panel potentiometer.
MAGPOWR Dancer / Follower Arm ControlRead More
Need control of a dancer, follower arm or both? No problem, as MAGPOWR’s DFC-90 and DFC-A low-cost tension controls can handle either operation mode.
Dancer Mode: The DFC-90 and DFC-A are full PID closed-loop dancer controls, controlling web tension by sensing the position of the dancer arm through a DFP or DFP-2 Position Sensor and adjusting the clutch, brake or motor control torque accordingly to maintain the dancer position set point.
Follower Arm Mode: The DFC-90 and DFC-A control web tension by compensating for measured changes in the roll diameter. Roll diameter changes are measured through the DFP or DFP-2 Position Sensor and a follower arm. An optional Stop Multiplier provides additional stopping torque to help stop large unwind rolls.
MAGPOWR Spyder Plus S1Read More
The new Spyder Plus S1 tension controller has all the existing features of the Spyder Plus controller, while adding an additional input for roll diameter. This input allows for additional powerful features normally reserved for our highest end controllers.
By referencing the actual measured diameter on this new input, this DIN rail mounted low-cost controller now includes very precise taper tension, hold level change options and inertia compensation options in load cell and dancer modes. In addition, gain compensation in dancer mode allows for a stable dancer from full roll to core, regardless of roll-build ratio.
Like the Spyder Plus, the Spyder Plus S1 is a controller that can be configured as an open loop, closed loop load cell or closed loop dancer modes, providing accurate, reliable control by providing feedback to clutches and brakes, or interfacing directly with drives in unwind, rewind or point-to-point applications.
Built in Modbus TCP communications provide the ability to easily interface and share data with an existing PLC, remote PC, HMI or web browser, allowing for remote set point adjustment to further improve efficiency, especially when multiple controls are used in the same process.
MAGPOWR Spyder Plus Tension ControlRead More
Designed for precise tension control, MAGPOWR’s cost-effective Spyder Tension Control is capable of controlling web tension in closed-loop, open-loop, unwind, rewind, point-to-point or dancer applications. It measures tension from one or more MAGPOWR load cells and outputs a corrective analog signal to control a torque device. Its reduced size means it can be hidden away in an enclosure or underneath the machine.
With its Ethernet connection, the easy-to-use Spyder can be viewed on a web browser for remote troubleshooting, programming and/or data collection. Additionally, the Spyder provides an analog input for Manual Level setpoint, control inputs for Run/Stop, Auto/Manual: Tension On/Off, and E-Stop, and a 0-1 mADC meter output proportional to measured tension.
Spyder Plus has the ability to control open loop applications, advanced features for dancer applications, and the ability to interface and share data remotely. Spyder Plus now has powerful features for dancer applications that were once only available with more expensive controls. Dancer mode now allows the unique ability to use load cells to monitor web tension, while remote setpoint adjustment improves efficiency, especially when multiple controls are used in the same application. Spyder Plus also works with third party ultrasonic or laser sensors to determine roll diameter.
