Absolute positioning of the elevator car for travel heights up to 392 m.

The contactless absolute measuring system for shaft copying – also called shaft information or positioning system – has an extremely compact, very robust design. In addition to the sensor, which detects the position of the elevator car 100% slip-free, it also includes the appropriate evaluation unit, a so-called Position Supervisor Unit (PSU). The safe system therefore consists of a SIL3-certified sensor and a suitable evaluation unit. This enables elevator and safety functions to be implemented in accordance with EN 81-20/21/50.


Sensors - reliable detection of position and speed values

Kübler offers various sensors for this purpose. The Ants LEB02 is used as a classic shaft copying system for precise positioning of the elevator car. The SIL3-certified Ants LES02 and Ants LES03 sensors can also be combined with various evaluation units from Kübler. The sensors from Kübler are particularly characterized by their compact and robust design.

Evaluation units - safe processing of position and speed values

In addition to sensors for safe position and speed detection, Kübler also offers the corresponding evaluation units.

Safe systems - realization of safety functions

By combining sensor and evaluation unit, safety functions can be implemented in accordance with EN 81-20/21/50. Kübler Safe Systems therefore make a significant contribution to the digitalization of elevator systems. Numerous mechanical components such as limit switches or even the classic overspeed governor can be eliminated. This saves space, time and costs.
