GIVI MISURE GVS 508
GIVI MISURE GVS 508 is a self-aligned absolute optical scale. Ideal for CNC machine tools, it has a resolution of up to 0.1 μm. The scale is easily installed, thanks to its symmetric design and self-aligned carriage. Available in standard length of 270, 320 mm, can also be ordered in length up to 30’000 mm
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.
