ET series Closed-loop Control Electronic Tensioner

Overview

Closed-loop tension control is achieved. The precision can be within 2% by automatic control (Limited to some models).

Multiple tensions can be set rapidly by changing the input signal for intelligent control purpose.
Tension is controlled by excitation currents to provide high precision and stability tension control, which is independent to winding speed.
Data monitoring and tension curve plotting is available by connecting with computers through RS232C port and our own-designed software. (Refers to figure below)

ET-F series electronic tensioner

ET-F series electronic tensioner consists of two brakes. The bigger brake for thick wires with higher tension range, while the smaller brake for thin wires with lower tension range.

ET-2000-FL Small Brake Big Brake Small Brake Big Brake
Φ0.10-0.25 Φ0.20-0.60 50-500 200-2000


Customized models are available.

ETD Series Electronic Tensioner

The tension is adjusted by current provided. Anti-tension force is adjusted by the slider.

ETD-2000 Φ0.20-0.65 200-2000


ETC Series Electronic Tensioner

Hystyeresis brake is adopted to provide the tension force so that no physical contact is involved in the system besides the bearing inside. It greatly improves the smoothness, stability and consistency of tension control, especially for the high speed operation.
