Electronic tensioners use tailor-made load cells as feedback to regulate tension to an exact desired point in a closed-loop control system.
The tensioner is the main component that maintains the appropriate tension during the process of coil, wire and cable
winding in order to produce quality products. In a usual open-loop system, the accuracy can reach to
within 10% of the preset tension value, while it is degraded to more than 20% if the mechanical tensioner is used.
Hysteresis Brakes with Electricity Applied to Tensioners
Hysteresis brakes are the core of ETA tensioners from Valid Magnetics Limited. When electricity is applied to the
field, it creates an internal magnetic flux. That flux is then transferred into a hysteresis disk passing through the field
without the use of magnetic particles or friction components. As there is no direct contact in parts when the torque or
tension force is generated, it is very durable and maintenance is very easy. The linearity of hysteresis brakes is excellent
within the specific torque range we selected for the tensioners so that the tension force is very accurate and smooth,
throughout the entire speed range.
ETA electronic tensioners from Valid Mgnetics Limited
Our ETA electronic tensioners utilize tailor-made load cells as feedback to regulate the tension to an exact desired point in a closed-loop control system. Tension tolerance or
precision is controlled within 2% tension variability or better. The tension is adjusted by the variable current supplied so that multiple tensions can be set rapidly by changing the input signal for intelligent control purposes, and can be monitored in real time by the latest OLED display.
And more importantly, with the ETA electronic tensioner, the tension regulation is independently controlled and not affected by the winding speed.
Application
ETA electronic tensioner technology can be used for tension control in the winding process for the manufacture of various products including wires, cables, yarns, transformers,
motors, relay coils, inductors and textiles.
ETA electronic tensioner features and advantages include the following:
• Easy installation and convenience: Simply set the required
tension value and the ETA electronic tensioner
works automatically.
• The Modbus RTU (485) communication protocol is
adopted: The tension can be monitored and remotely
controlled via PC, PLC and other different industrial
control equipment.
• Real-time tension checking: Upper/lower tension limit
alarm, wire broken alarm can be set.
