Compensating rolls are used, for example, in printing plants to compensate for variations in the tension of the paper web. The position of the compensating roll is determined either linearly or rotatably. Depending on the machine design, the recommended products are our magnetostrictive linear sensors (from the OMS2 series) for linear detection or our Hall-effect angle sensors (from the HTx25K series) for rotary detection. Both sensor types support wear-free and dust-proof operation, making them highly durable. The rotary encoders and displacement sensors are housed in a metal enclosure to provide a high degree of protection. In addition, the robust sensor design means they can withstand a wide range of oscillating movements. The connectors of both sensors are also adapted to environmental requirements: The OMS2 series displacement sensors are equipped with a robust connector, and the HTx25K series encoders are connected via a strain-relieved round cable.
All in all, the displacement and angle sensors are not susceptible to environmental stress. As such, they make a significant contribution to the smooth, reliable and long-lasting operation of the system.

The ETA25PM series of programmable multi-turn encoders is ideal for implementing window drive systems in greenhouses. The compact encoder is capable of absolute detection of up to 200 revolutions, eliminating the need for a gear stage at the design phase. As drives are usually offered with a fixed rotational speed, you would normally need to stock several types of encoders to ensure you have the right rotational range for each application. Or, simply use our angle sensor: It can be programmed to provide different electrically effective ranges of rotation from 0° to 72000°. This means that a single component or encoder type can be used for any application, simply by setting the required angle of rotation.
The multi-turn encoder offers high resolution, enabling extremely accurate positioning. It reliably transmits a high quality signal without interruption. As the MEGATRON multi-turn encoder operates without a mechanical end stop, accidental overshooting of the measuring range, which can occur when the drive starts up, will not destroy the rotary angle sensor. The non-contact measuring principle does not rely on a drag contact, so there is no mechanical wear. This results in very long sensor life and reliable operation.
Only one type of rotary angle sensor is required to ensure correct window repositioning by the drive. These features make the ETA25PM series magnetic encoders the ideal product for flexibly adjustable drives.
