Height Gauges
SERIES 518 – Linear Height Digimatic 2D Measurement System
•
Excellent accuracy of (1.1+0.6L/600) μm with
0.1 μm / 0.4 μm resolution/repeatability.
•
High-accuracy Height Gauge incorporating a
wide range of measurement functions.
•
To achieve best-in-class accuracy, a high-accuracy
reflective-type linear encoder and an exceptionally
straight guide are used.
•
Measurement can be implemented by icon-based
commands that also support easy one-key
operation. Perpendicularity (frontal) of 5 μm and
straightness of 4 μm are guaranteed.
•
A best-in-class large colour LCD with excellent
visibility is used.
•
Pneumatic full/semi-floating suspension system
allows adjustment of air-cushion height.
•
Basic statistical functions are provided and,
additionally, RS-232C data output provides the
option of evaluating measurement data externally
with SPC software on a PC.
Running the pneumatic suspension allows
frictionless movement on a surface plate.
Power grip provides precise handling.
