Loop Controls
Ultrasonic
Non-Contact Loop Control
•
System is unaffected
by surrounding noise, electrical fields
or shop oils and dust.
• A free loop, even at high speeds, can be kept under precise control without erratic stop and start motions.
• Special stock types and configurations can be processed without damage--regardless of coil coating finsihes, density or opacity. Widths can be as narrow as .01".
Precise
Variable Speed Material Flow
This control automatically adjusts the operating
speed of payout, straightening and rewind equipment to maintain a free
material loop and to match material flow to a required line speed. There
are no moving parts, no stock contact, no loop sensing arms, mechanical
linkage or other loop control hardware. The control works with equal precision
for both conductive and non-conductive materials.
Ultrasonic pulses locate the material position anywhere in the sensing range. Signals are then transmitted to an integral microprocessor which programs the speed of the payout or rewind equipment.
