Steel

Kübler pulses for the heavy industry. Reliable and sturdy.

On oil platforms and offshore plants, in open-cast or underground mining machines, in crane installations and in steel plants - Kübler encoders operate reliably in heavy machinery in the harshest environmental conditions with dust, moisture and extreme temperatures and mechanical stress. Usually, in these unfriendly environments, high-accuracy sensors reach their limits.
This is not the case with Kübler - With its wide-ranging products portfolio, the Company boasts more than 50 years of experience in mechanical engineering and automation technology. Heavy Duty encoders and rugged compact encoders equipped with particularly robust bearings, wit the most modern housing technologies and many various communication interfaces (from analogue up to the real-time Profinet interface) are part of our wide heavy industry-specific products range.
Encoders for functional safety and optical fibre modules for the secure optical transmission of encoder signals over long distances complete the Kübler product range for these application fields.

Speed measurement and positioning of rollers and
drives in the steel industry

Position and movement sensors play an important role in steel plants. Even though they are exposed to harsh environmental conditions, the encoders must ensure an uninterrupted and safe process. Kübler encoders work steadily for many years in steel plants all over the world. Reliability is the main feature, especially for plants with very high operating costs.

1. Steel production
Positioning and speed regulation of cranes and trucks. Rugged sensors in very dusty environments with high mechanical requirements regarding shock and vibration resistance.

2. Steel casting

Technologies for the heavy industry

Innovations from tradition. Kübler products benefit from 50 years experience in automation engineering. Over the years they have undergone ongoing development and been optimised for use in the heavy industry. Small details make a big difference. Our products feature many intelligent, high-quality extras, which offer our customers decisive advantages, whilst at the same time making a significant contribution to the high availability and safety of the machines.

Optical Multiturn Technology

100 percent resistant to magnetic fields - extremely compact design. Even strong magnetic fields, as occur in the vicinity of brakes or drive motors, pose no problems for the sensor technology of optical single- or multiturn devices. The technology dispenses with any components that may be susceptible to magnetic influences. As a result of the proven drive, the encoder has no need of a battery to store the number of revolutions.

Insensitive to interference: OptoASICs

The resistant Kübler OptoASIC technology offers a very high integration density of components. This means that, on the one hand, the reliability in the application can be increased significantly, and on the other hand the technology demonstrates quality EMC characteristics and shock resistance.

Well protected against dust and moisture

The sturdy, thick-walled die-cast housing of the Sendix encoders is press-fit stemmed several times on the encoder flange. The high protection level and the wide temperature range from -40°C to +90°C allow a safe outdoor operation. The die-cast housing is fitted with an extremely resistant base, on which the connector flange is screwed with four screws.

High temperatures

High heat resistance - combined with high rotational speeds - make the Sendix encoders the optimal solution for all applications in a high temperature environment. Also the used seals, cables and connectors withstand extreme temperatures.

Shock and vibration resistant

Kübler encoders avoid serious, expensive failures right from the start - even with increased levels of axial loading, shock and vibration. This can eliminate enormous service costs and expensive downtimes in applications worldwide.

Sea-water resistant versions

Although it has already proved itself in harsh environments, the Sendix family of devices has now been tested and certified to IEC 68-2-11 for resistance to the effects of salt-spray over a period of up to 672 hours - the highest test level. The high certification level for the Sendix encoders attests a high level of corrosion resistance.
