October 2017
At the interlift 2017 (17 to 20 October) in Hall 5, Stand 5095, Kübler will be presenting its latest sensor solutions. Kübler has been providing sturdy, reliable encoders to the best-known names in the industry for years.
Kübler created a new measuring system for absolute shaft copying, inspired by the idea "everything from one source." Moreover, this system is SIL3-certified and as a result meets the requirements of the recently introduced standards EN 81-20 and EN 81-50.
The measuring system is mounted directly in the lift car, thus ensuring permanent recording of the absolute position. The absolute position feedback makes a reference trip unnecessary in the event of a power failure, since absolute position values with a resolution of 1 mm are available at all times up to a total conveyance height of up to 392 m.
This not only saves time and costs, but enhances the availability of the lift, to the benefit of all lift users. Consequently, unnecessary reference / learning trips are a thing of the past.
Currently, it is the most compact measuring system for absolute shaft copying (135 x 45 x 33 mm). The system can also be deployed even in the most cramped installation spaces in the event of retrofitting, modernisations or in existing buildings / lift shafts or new installations.
The extremely compact housing and robust stainless steel belt that runs around the housing contribute to the virtually silent operation of the system.
There is nothing worse than complex, long drawn-out installation. Such effortless assembly is a USP. The system is delivered with an assembly kit. The sturdy stainless belt is simply suspended from a spring hook included in an assembly set and attached in the shaft pit with a spring element.
Compared to other measuring systems, no other attachment elements or anything of the kind need to be added for the installation of the system in the Kübler measuring kit. In addition, the stainless steel belt is very strong and can withstand scratching or bending during installation.
The measuring system is designed for conveyance heights of up to 392 m with a resolution of 1 mm, making it suitable for 99.9% of all lifts worldwide. Küber provides three possible versions with the relevant interfaces of the lift industry:
• LEB, basic version
• LES, safe version SIL3-certified
• LES, safe version + evaluation unit + UCM module
All safety and lift functions will be presented live with a demonstrator. The installation renders many components superfluous in the lift shaft, such as magnetic switches. This greatly reduces complexity and the installation time.
