Dancer or Load Cells – Which Should I Use?

I am frequently asked this question, and my standard answer is that: it depends. It depends upon the type of process (slitting, printing, coating, laminating, die cutting, etc.), the range of products being run (rigid, extensible, deformable, etc), whether flying splices and/or turrets are involved, and incoming roll condition.
Dancers are very effective at minimizing web tension upsets due to out-of-round master rolls, rapid speed changes, indexing operations or any other process that introduces tension instability. The ability of a dancer system to absorb these upsets with the storage inherent in the system clearly offers some advantages for good closed-loop tension control. There are a few things to keep in mind when comparing or considering a dancer system for control.
Z4-UI Dancer Controller with Tension Indication
Montalvo pioneered dancer tension control when we introduced the only controller on the market to capitalize on the benefits of both load cells and dancers within one highquality tension controller.
The Z4-UI represents the next advancement in dancer tension control technology. Designed for unwind tension zones utilizing dancer arm feedback for control and load cell feedback for tension indication giving you the best of both worlds and maximize your capability and productivity.
The Z4-UI features the only dancer controller with a 7″ HD interactive display screen, and 5 day trend storage. Additional features include:
- Compatible with Pneumatic and Electric Brakes
- Compatible with Drives
- Muli-Lingual HMI
- Upgradeable Communications
- User Defined Units and Scale
- Multiple Installation Options
The Z4-UI also offers a wide range of high performance functions while still being easy to set-up and operate:
- Soft-Start
- Anti-CoastSplice
- Web Break Detection
- Remote Setpoint
- Progressive Gain
- Programmable Diameter Alarm
- Range Expansion
- Remotely Turn Tension On/Off
