The AMOSIN® measuring systems function on a patented purely inductive principle. The measuring scale is a stainless-steel tape onto which a high precise periodical graduation of variable reluctance has been etched using photo-lithographic techniques.

A coil structure, with a number of coils aligned in the direction of measurement, is implemented on a substrate using micro-multi-layer technology. The relative angular movement in the direction of measurement between the sensor structure (in the scanning head) and the measuring scale periodically changes the mutual inductance of the individual coils, generating two sinusoidal signals with a 90° phase difference.

The extremely accurate signal, and its immunity to environmental influences, has the effect that, after conditioning of the signal in the evaluation electronics deviations of no more than 0.1% from the ideal sinusoidal form (harmonic content) remains. This allows high interpolation factors to be carried out in the course of signal digitization.

The AMOSIN incremental linear measuring systems consist of a stainless steel inductive Grating Scale and a non-contact electronic Reader Head. With an IP-67 rating and inductive sensor technology, they have high tolerance to many industrial contaminants. These encoders can be employed in both clean and polluted environments.

The AMOSIN incremental linear measuring systems deliver high-performance position feedback that is suitable for closed loop motion control either as the primary encoder (direct drive linear motor) or as the secondary encoder in a ball screw driven axis. They are of value in general for drives where high dynamic range and stiffness is required.

Our Linear Scales are produced incorporating two highly accurate grating tracks – one incremental and the other a coded absolute pattern, using a precision etched photo-lithographic process.

The Encoder Heads incorporates a micro coil array sensor along with analog and digital evaluation electronics. The absolute position value is acquired in real time and interfaces including SSI, BiSS/C, and CNC control protocols.

Measuring Inside and Outside Diameters, we offer open hollow-shaft measuring systems, and do not have their own bearings or require any couplings for mechanical connection. Operating entirely on an inductive basis achieving accuracies less than +/-2µm arc length or better.

Our Encoders are well-protected from environmental influences such as dust, humidity and so forth and feature extremely high resistance to shock and vibration. They are not sensitive to electromagnetic interference of any kind and has no hysteresis in contrast to magnetic measuring systems.

Inside and Outside ABSOLUTE Diameters, we offer open hollow-shaft measuring systems, and do not have their own bearings or require any couplings for mechanical connection. Operating entirely on an inductive basis achieving accuracies less than +/-2µm arc length or better.

Our ABSOLUTE Encoders are well-protected from environmental influences and feature extremely high resistance to shock and vibration. They are not sensitive to electromagnetic interference of any kind and has no hysteresis in contrast to magnetic measuring systems.
