ELECTRO-MAGNETIC TENSION CONTROLLERS
Measure and Control Tension on any Moving Web

GENERAL DESCRIPTION
The CLEVELAND-KIDDER Type UCM Electro-Magnetic Controllers offer advanced, state-of -the-art tension control technology. Features include a signal printed circuit board design with easily adjustable response circuitry, rapid stop circuitry, stall condition operation, automatic or manual mode operation, bumpless switching between modes, adjustable brake/clutch demagnetization circuitry, and selectable readout of web tension or controller output current. Available options include tension limit detection, and taper tension circuitry.

The CLEVELAND-KIDDER Type UCM Controller, when combined with patented CLEVELAND-KIDDER Tension Transducers and an electrically activated brake or clutch, provides a highly responsive, closed-loop control system.

 
The single printed circuit board contains a regulated DC power supply to the transducers and all necessary circuitry to monitor, control, and compensate the desired tension characteristics in a moving web. Actual web tension is sensed by the transducers, displayed on a tension meter, and compared with the desired tension which is set by the process operator

Because brake or clutch torque is constantly controlled as a function of actual web tension, the closed-loop system compensates for changes in roll diameter, machine speed, and brake or clutch "fade". Compensating circuitry reduces controller gain at critical frequencies, providing stability, while permitting high gain and fast response to allow high operating speeds.

STANDARD FEATURES
  • Provides transducer excitation.
  • Solid state circuitry with terminal board connection on a single printed circuit card.
  • Compatible with all CLEVELAND-KIDDER Tension Transducers.
  • 8:1 full scale tension calibration range.
  • Compensation circuitry for optimizing response and stability during start-up, operation, stall, or manual to automatic operation switching.
  • Selectable automatic or manual operation.
  • Selectable readout of web tension or controller output current.
  • Adjustable negative current bias.
  • Accessory output 0-10 VDC for tension recorder or remote meter.

PRODUCT BENEFITS

  • Closed-loop tension control helps to provide consistent product quality.
  • High system response using patented, negligible displacement transducers minimizes scrap loss.
  • Industrial quality solid state circuitry reduces down time.
  • Ease and compactness of installation.
  • Simple system calibration and start-up
