The Magnescale DK830S is a high-precision digital gauge designed for demanding industrial applications requiring sub-micron resolution, robust construction, and reliable repeatability. With a 30mm measuring range, this slim, stem-type gauge is ideal for integration into machine tools, inspection stations, and automated systems.

Key features

Measuring range: 30mm
High accuracy: 1.3μm(DK830SR/SLR), 1.7μm(DK830SVR)
Maximum resolution: 0.1μm
High response speed: 80m/min
Built-in reference point
Spline design applied to spindle bearings, thus improving reproduction of the detection accuracty.
Pneumatic push type (DK830SVR)

Available in multiple configurations—including spring push and pneumatic push types – the DK830S series offers flexibility for various mounting orientations and measurement setups.

Applications

Precision inspection systems
Automated measurement rigs
Machine tool integration
High-speed dimensional control
