Angular Measuring Encoder with multi-head scanning

MHS

The AMO – Angle measuring encoders with multi-head scanning allow for circular and rotating axes enable absolute accuracy down to a few arc seconds.

Eliminated is the influence of an eccentric mounting on the positioning accuracy of the measuring flange, and the system accuracy of the measurement encoder is increased by at least a factor of two times better as compared with a one encoder head measuring encoder.

There are two types of measuring system:

MHS – Multiple Head Solution

The MHS – Angle measuring encoder consists of a measuring flange or ring scale, 2 encoder heads and the signal processing electronics unit. The dual head design eliminates the dynamic in-motion eccentricity effect as the axis rotates due to external side forces on the axis and increases system accuracy by a factor 2.
