The latest development from SCHNEEBERGER, the AMSA 3L distance metering system, has been conceived especially for extra long axes.
AMSA 3L is now made possible by highly accurate machining and measurement of the rails. A special design of the rail ends for butt joints, when used in combination with the AMSA 3L reading head, allows the carriage to run over the butt joint, so that measuring axes of any desired length can be constructed.


SPECIAL FEATURES:

* Long measuring lengths can be achieved by means of butt joints
* System dimensions correspond to those of our product RSR
* Precise overall length, L3, of the rail
* The special design of AMSA 3L allows the carriage to pass over butt joints without loss of signal
* Complete interchangeability of rails, carriages and reading heads
* One reading head for all sizes
* Integral metering head electronics



AMSA 3L CONCEPT:

To achieve a high level of availability of AMSA 3L components worldwide, each size is manufactured in 3 m segments, and both ends of a segment are pre-pared for the AMSA 3L butt joint.
The rails can be joined together to build axes of any desired length. Special lengths at the start and end of a measuring axis are cut to length using a simple cutting-off machine. The butt joints along the measuring axis are adjusted on assembly to achieve correct phasing using a special installation tool.
Because single rails are 100% interchangeable, they can be replaced in the field at any time. The proven concept from our standard program, "One reading head for all sizes", has been adopted here too, so that, for AMSA 3L, a minimum of spare parts ensures a high degree of availability in service.
