Each scale is embedded in a hardened stainless steel blade, free from racks, pinions, or glass components. They include a resolution of 0.0005" / 0.01 mm, unlimited response speed, IP66 dust/water protection, and functions such as power control, data hold, and unit conversion.

FAQs

What are the key features to look for in a DRO linear scale?
High accuracy, suitable resolution, and ease of installation are the features to consider. Other factors to consider are measurement range, the sensor, and the quality of the readout display. Easy to maintain and has readily available replacement parts.
What is the difference between absolute and incremental measurements in DRO systems?
Incremental measurements track position changes from a reference point but lose data if power is lost, while absolute measurements provide the exact position at any time, regardless of interruptions. Absolute measurements offer more precision and reliability, whereas incremental ones are simpler and often cheaper.
Can I install DRO linear scales on my existing machinery? If so, how?
Yes, you can. Select the appropriate scale, prepare the mounting surface, and attach the scale securely. Connect the cables, connect the sensor and encoder following the manufacturer's instructions, calibrate the system, and verify your measurements.
What types of materials are DRO linear scales suitable for measuring?
They are suitable for measuring various materials, including Metals like steel and aluminium, plastics, wood, composites, glass, and ceramics. The choice of scale depends on the material's properties and the specific project requirements.
What is the expected lifespan of a DRO linear scale, and how can I extend it?
They typically last about 5 to 10 years with proper care. To extend its lifespan, regularly calibrate the scale, keep it clean and free from contaminants, and shield it from extreme temperatures and moisture. Proper installation, gentle handling, and follow the manufacturer's maintenance guidelines.
What are the differences between capacitive and magnetic DRO scales?
Capacitive scales detect changes in capacitance, providing greater accuracy and finer resolution in measurements. Magnetic scales use magnetic fields for measurement. Magnetic scales may not match the accuracy of capacitive scales, but they offer increased durability.
What is the impact of coolant or dust on the long-term performance of digital scales?
Coolant can cause corrosion and damage sensitive components, while dust can clog up moving parts and interfere with the load cells. Both instances can lead to inaccurate readings.
How does the SPC data output feature help in quality control processes?
The SPC (Statistical Process Control) data output function enables continuous detection of conformity to defined criteria and rapid corrective actions, which helps minimize waste and contribute to product quality. SPC watches the process in real-time to detect trends and where issues might occur before the events happen.
