GVS 508
Absolute optical scale for CNC machine tools
- Absolute optical scale with glass measuring support.
- Serial interface SSI – BiSS C (unidirectional), with or without 1 Vpp analog signal.
- Resolutions up to 10 nm.
- Accuracy grade ± 5 μm in the standard version and ± 3 μm in the high accuracy version (± 2 μm for measuring lengths up to 670 mm).
- High resistance to environmental dirt.
- Central fixed expansion point (FEP). On request positioned on the right (RT) or on the left (LT), for a linear expansion consistent with the type of application.
- Metrological certificate provided with each scale.
- Linear thermal expansion coefficient λ = 8 x 10-6 °C-1.
- Direct reading of absolute measure.
- Connector on the transducer.
- Protected against inversion of power supply polarity and short circuits on output ports.
- Small size, to allow installation in narrow spaces.
- Pressurization from both sides of the scale or from the transducer.
