Inductive_LinearTapeEncoders - 2

AMOSIN Technology - General information Based on the tried and tested AMO technology of length and angle acquisition where a high precision graduations with structures etched photolithographically in steel are scanned, a future-oriented generation of measuring systems has been created that incorporates newly developed inductive sensors and an integrated electronic evaluation circuitry (ASIC). This generation of measuring systems opens up a vast range of applications from demanding machine tools or measuring machines through to handling systems or special installations for metal machining...

The relative movement in measurement direction between the sensor structure (in the scanning head) and measuring scale periodically changes the mutual inductance of the individual coils and generates two sinusoidal, 90°-phase shifted signals (SIN and COS). The excellent signal quality and stability to environmental influences ensure that, after signal conditioning in the electronic evaluation stage (Fig. 2), deviations of only 0.1% of the ideal sine-wave form (harmonic content) remain. This feature enables high interpolation factors (subdividing stages) in signal digitisation either in the...

Measuring accuracy The overall measuring accuracy of a measuring system can be influenced by following deviations: Graduation deviations of the absolute reference length in the measuring scale (graduation accuracy) Deviations within the grating pitch determined by the signal quality and internal electronic evaluation stage (interpolation error) Since AMOSIN measuring systems are based on a modular design and the measuring scales as well as measuring slides of the same type are exchangeable, the system accuracy can be attributed to the two device components: The accuracy of the measuring...
