Auto Web Tension Control System

 
 
Four Line LCD Display
To show various parameter’s as per requirements.
Set Tension
Shows the set tension.
Web Tension
Shows actual web tension.
Line Speed
It shows web speed in meter / min.
Counter
Shows material length in meter.
Time
Total process ON time in minutes.
Output voltage
Shows output voltage to the Brake/Motor.
 
No manual set valve
 
PURETRONICS web tension controller stores the last output voltage to Brake / Motor, whenever machine is stopped or power Off takes place it starts the machine with old memorized value, which gives least variation in the tension, gives the leading edge.
 
User's Friendly
 
For Operation easiness, 10 turn Tension set pot is provided to set the desired tension. Start ON - OFF switch with indication.
