Incremental glass scale for CNC machine tools / from 70 mm to 3'240 mm / ± 3 μm

GVS 600

• Optical scale with glass measuring rest, especially suitable for CNC machine tools.
• Resolutions up to 10 nm.
• Degree of accuracy ± 5 μm in the standard version and ± 3 μm in the high-precision version (± 2 μm for measuring lengths up to 720 mm).
• Non-extensible sealing lips along the sliding surface of the reader head, attached to the lateral ends.
• Innovative device inside the scale for the disposal of liquids coming from inefficient filtration systems.
• The special sealing lips and the liquid disposal device provide excellent protection of the scale from cooling liquids often used during machining.
• A metrological certificate is supplied with each scale.
• Linear coefficient of thermal expansion λ = 8 x 10-6 °C-1.
• Adjustable connection cable output. Connector inside the transducer.
• Reference indices with coded distance or with constant step, with predefined or or selectable positions.
• High accuracy and stability of signals even at high speeds, strong accelerations and vibrations.
• Protected against power supply polarity reversal and short circuits at the outputs.
• Small size to allow installation in tight spaces.
• Interchangeable with the previous model NCS.
• Filter system for pressurization available on request.
• Measuring length:70, 120, 170, 220, 270, 320, 370, 420, 470, 520, 570, 620, 720,770, 820, 920, 1020, 1140, 1240, 1340, 1440, 1540, 1640, 1740, 1840, 2040, 2240, 2440, 2640, 2840, 3040, 3240 MAX mm
