KDT-B-600 Atutomatic Constant Tension Controller High Precisely Fast Response
    The tension control of the tension controller refers to the ability to permanently control the tension of the tape as it is transported on the device. The automatic tension controller KDT-B-600 is an automatic control system that realizes constant tension control. In many industrial such as paper, textiles, plastic film, wire, printed matter, magnetic tape, metal strip wire, etc., the rewinding and unwinding tension of the material is critical to the quality of the product. Constant tension control is required for this purpose. The automatic tension controller is an automatic control system that realizes constant tension control. Its function is mainly to achieve synchronization between the rollers and continuously uniform control of rewinding and unwinding. Automatic tension control system consists primarily of an automatic tension controller, pressure sensor, magnetic powder brake or clutch.

1. Working with load cell.

2. Fast response.
3. Precise control the tension.
4. Tension sensors roller monitor the roller tension of the material and amend any changes of the tension.

5. Maximum tension can up to 600N.

6. Mutli connection MODBUS RS485.


    Control mode

1. Manual panel control. 

According to the winding unwinding situation, the manual knob adjustment is manually performed to control the magnitude of the exciting current to obtain the required tension.

2. External PLC control.

The PLC needs to be equipped with a 10V analog output module. With the tension detector, automatic constant tension control can be formed, or manual adjustment can be made through the touch screen. 

3. External potentiometer control

The short wiring of +10V and ADJ needs to be removed, and the panel knob must be twisted to the right.

Note: The magnetic powder brake and clutch wiring is not divided into positive and negative poles.



  1. Printing systems: conveyors and in-feeders
  2. Wood-working systems: saws, wood-working machine, laminators
  3. Testing systems: lab machines, durability testers, measuring systems
  4. Food processing systems: meat cutting machines, cookie making machines, canning machines, noodle making machines

Fast operation and usage

1. Install tension detector: According to the item of wiring diagram and connect the input, output and power lead of the controller correspond.

2. Start the machine and check the tension detector: Turn on the power of the controller after finishing installation. Press the menu into number six to check whether the tension detector install correctly or not. If correctly, the value of the two tension detectors should between 1000-2000, and this time you press the tension detector by hand, the value will be increase visibly.

3. Remove the tare: Press the menu into number one before the material on the tension detectors, meantime press the execution switch, the tension controller will get rid of the external weight of the tension detector to make the measure tension of the controller to be zero.



1. Automatic unwind tension system deploys material tension detection roller.
2. The device will support auto-stop operation when material tension reaches the upper and lower limitation.
3. Unwinder device deploys automatic compensation tension control device.
4. The rotation speed then pre-set tension maintain by the roller when printing material rotate through the printing machine, no matter what the size, width, material.
5. Tension sensors roller monitor the roller tension of the material and amend any changes of the tension.

1. When can I get the quotation?
We usually quoted within 24 hours after receiving your inquiry. If you are very urgent to get the price, please call us or tell us in your email, so that we can regard your inquiry priority.
2. How should I place the order?
Please let us know the model number based on our specs for powder clutch, powder brake, air clutch, air brake, electromagnetic clutch, electromagnetic brake and safety chucks. For air shaft and roller, please show us your drawing, or let us know your request, and then we will provide you drawing for confirmation.
3. What’s your MOQ basis?
Normally, we don’t have MOQ request, except the rollers.
4. What about the lead time for production?
Honestly, it depends on the order quantity and the type of our products. For powder clutch, powder brake, tension controller, load cell and edge position controller which is about 3-5 days. For safety chucks, air shaft and roller which need about 15-30days.
5. What is the term of delivery?
We can arrange with EXW, FOB, CIF…etc. You can choose the most convenient one or cost-effective way.
