In rolling mills, loopers are normally used to control the tension of the metal strip between roll stands. The rotational angle of the looper is measured by a feedback encoder designed to meet special requirements.  The slight swing motions of the looper can result in poor grease distribution in the ball bearings and insufficient lubrication. The encoder is also subject to high levels of shock, vibration and temperature loads, as well as oil, cooling emulsions, and water at the installation site. The standard encoders used to date by customers have been unable to meet the required service life due to these harsh conditions.

For this reason, Johannes Huebner Giessen developed a special looper encoder, which boasts a considerably longer service life thanks to specially engineered features. It has bearings designed to meet the specific challenges, with a 40 % higher dynamic load rating and a specially formulated lubricant. The bearings, while not necessarily designed for high speeds, will withstand high shock loads up to 450 g. A special radial shaft sealing ring with additional protective lip provides the required protection class in harsh ambient conditions. As a result of this special design, the Huebner looper encoder offers superior reliability and extended service life.

Advantages at a glance:

- Encoder with most robust aluminum housing existing on the market

- Extremely high resistance to vibration and shock

- Degree of protection up to IP 67

- Latest sensor technology for highest signal accuracy for high end process quality

- Up to 1 million pulses per revolution

- Internal diagnostic with error output

- direct fiber optic signal transmission as option

The U-ONE® is a universal basic unit connected to electronic function modules in the switchgear cabinet via optical-fiber cables that are immune to EMI. Alternatively, a compact version is available. There the electronic function modules are just backpacked to the detection unit.

The electronic function modules are linked by an internal bus structure.

A large number of possible electronic function modules results in high planning flexibility and easy expandability for later additional requirements. This concept offers considerable cost savings, thanks to its simple mechanical fitting, standardized electronic function modules, and reduced wiring requirements.
