Exposed Linear Encoders

|
LIDA
incremental linear encoders use AURODUR steel scales with
grating periods of 40 µm as measuring standard. The new LIDA
models are relatively insensitive to scale contamination and
unevenness of the mounting surface. |

The
AURODUR steel scale tape of the LIDA 101/LIDA 171/LIDA 181
is cemented into a steel scale carrier and then calibrated. A
calibration chart is supplied with every scale. |

The LIDA
105/ LIDA 175/LIDA 185 is intended for larger measuring
lengths up to 30 m (100 ft). Here the one-piece AURODUR steel
scale tape is inserted into a scale housing consisting of
several standard sections; it is then stretched to a defined
tension and fixed at both ends to the machine bed. |

The
LIDA 107/LIDA 177/LIDA 187 also consists of a
one-piece steel tape. In this case, however, it is
guided in a scale-tape carrier and is rigidly connected
at its center to the machine. Measuring lengths up to 6
m (237 in.) are available. |
