Automatic Tension Controller

Automatic Tension Controller 

Introduction:

Automatic tension controller is mainly made up of tension detector, high accuracy A/D, D/A converter and microcomputer of high performance…etc. It realizes permanent tension of roll materials according to compare the tension of roll material measured by tension detector with the goal tension of settlement first, then through microcomputer PID operation and adjusting D/A output to change excitation electric current of magnetic powder clutch/ brake or torque of servomotor automatically. The controller can be used in several occasions needed to carry on measuring and controlling accurately with the tension and have application extensively with flexible in usage.

Feature

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.
