Tension Control
Precise control of a web, a cable, or a wire through the converting process requires for the product to be kept in tension when going over each of the rolls to manage the product elongation and to keep it as constant as possible.
Closed Loop Tension Control with DGT300+
Closed loop systems deliver superior accuracy and can be simply achieved with the Merobel DGT300+ Controller, EMP Brake or Clutch, and Force Sensors in combination with our range of load Cells from our supplier FMS. The web tension is maintained by continuously monitoring the difference between the set point and the load cells feedback measurement. The torque is automatically adjusted through a PID regulator to keep the actual tension at the set point, even during acceleration and deceleration. By design, the actual tension applied to the material is available for display and / or record.
Closed Loop Advantages
- Reliability & Repeatability
- Accuracy – Improve Product Quality
- Efficiency – Improved Control Process
- Increasing Production Rates
- Reduce Material Wastage
- Other Setups: Dancer Arm, Motor Speed Control, Diameter Sensor

For many years, MEROBEL has reinforced its worldwide position as a major manufacturer for both EMP Brakes & Clutches and associated electronic controllers. This leadership is especially well known for all the industrial applications related to web, wire & cable tension control, and torque simulation test benches.
