WMI - Angle Measuring Systems


AMOSIN angle measuring systems can be applied to a wide range of applications due to the pure inductive scanning principle and the robust IP 67 rating. A stable press-fit steel measuring tape ring scale provides the foundation for a flexible design and allows a wide range of ring scale diameters. Almost any diameter from about 80 mm up to several meters can be provided. This opens the use for large application fields from the slow, extremely precise positioning of a turntable through to the high speeds and the closely controlled velocities of a machine spindle.

Typical applications:

• Turntables
• Swivelling axes
• C-axes
• Working spindles
• Direct drives
• Medical equipment
• Printing machines
• Roller positioning
• Punching machines
• Electronic production equipment

The integration of the AMO non-contact encoder ring scale directly onto the rotating part, very close to the bearing and without a mechanical coupling is the best solution for precision positioning and high accuracy. Since the system has a high protection level - IP 67, it permits operation even in an oil bath. This offers compact integration of the inductive measuring system, leading to stiffer and space-saving designs, with lower masses and therefore lower moments of inertia.

The patented CHS model, which is a unique angle measuring system with self-calibration functionality, achieves very high accuracy on rotary axis. Accuracy errors related to mechanical installation, disc eccentricity and bearing run-out are removed in an economical way. The MHS version is a dual encoder head system that eliminates eccentricities “real time”.
