LinkHigh Resolution 30mm digital gauge
The Magnescale DK830S Series digital gauge delivers industry-leading precision and reliability for demanding industrial measurement applications. Designed with advanced MR sensor technology and robust ball spline spindle construction, the DK830S offers sub-micron accuracy, exceptional durability, and seamless integration with modern automation systems.
Key features
- Sub-micron Precision: 0.1 μm resolution and ±0.1 μm repeatability for highly accurate results
- Measuring Length: 30 mm stroke for versatile industrial applications
- No Warm-up Time: Ready to measure immediately on power-up
- Temperature Stability: Consistent accuracy across a wide temperature range
- No Calibration Required: Digital signal processing eliminates the need for manual calibration
- High Response Speed: Fast sampling and real-time data output for dynamic applications
- Robust Ball Spline Spindle: Over 270 million cycles, 5x greater radial load strength
- IP67 Protection: Resistant to water, oil, and harsh environments
- Traceable Quality: Supplied with accuracy charts and calibration certificates
- Flexible Connectivity: Compatible with PLCs, LT30 counters, MG80 interface units, and USB option


Advanced features
- Ball Spline Spindle Design: Multiple bearing contact points deliver stable resistance and smooth movement across the entire measurement range. Radial load capability is 5x stronger than conventional designs, ensuring accurate measurements even at an angle.
- Magnetic Detection Principle: Proprietary MR sensor technology provides high environmental resistance, strong temperature stability, and high-speed sampling (up to 20 MHz). No tracking errors, no thermal drift, and no calibration required.
- Environmental Protection: IP67-rated probe section resists water, oil, and condensation. The DK830S is built for longevity and low maintenance, reducing lifetime costs for your operation
- Traceability & Certification: All Magnescale digital gauges are traceable to national measurement standards. Calibration certificates are available for ISO compliance, and each unit ships with an individual accuracy chart.
