Buying Considerations
When selecting the Keyence LS-7601 Laser Micrometer for your application, several critical factors must be evaluated to ensure optimal performance and return on investment:
1. Measurement Requirements Analysis:
Determine your specific measurement needs including part size range, required accuracy (±1 µm standard), and measurement speed. The LS-7601's ±99.99999 to 9999.9 mm range covers most industrial applications, but verify your maximum and minimum dimensions fall within this capability.
2. Environmental Conditions:
Assess your operating environment for factors that could affect measurement accuracy. While laser micrometers are generally robust, extreme temperatures, excessive vibration, or heavy dust/contamination may require additional environmental controls or protective enclosures.
3. Integration Requirements:
Consider how the micrometer will integrate with your existing systems. The M18 threaded mount and M12 connector provide standard industrial interfaces, but you may need additional mounting hardware, cables, or interface modules for your specific automation systems.
4. Operator Training & Support:
Evaluate the technical expertise available in your facility. While the LS-7601 features intuitive operation, proper calibration and maintenance require trained personnel. The one-year warranty provides peace of mind, but consider ongoing support needs for long-term reliability.
5. Total Cost of Ownership:
Beyond the initial purchase price, consider calibration costs, potential downtime, and the value of increased measurement accuracy in reducing scrap and rework. The non-contact nature of laser measurement eliminates wear on measurement surfaces, reducing long-term maintenance costs compared to traditional contact methods.
6. Future Expansion:
If you anticipate expanding your measurement capabilities, consider whether the LS-7601 can be integrated into larger measurement systems or networked with other quality control equipment.
Frequently Asked Questions
Q1: How does the Keyence LS-7601 compare to traditional contact micrometers?
The LS-7601 offers several advantages over contact micrometers: it eliminates measurement errors caused by part deformation from contact pressure, provides faster measurement speeds (up to 2400 measurements/sec), offers better repeatability between different operators, and doesn't suffer from wear on measurement surfaces. For delicate components or high-volume production, laser micrometers typically provide superior accuracy and throughput.
Q2: What types of materials can the LS-7601 measure accurately?
The LS-7601 can measure a wide variety of materials including metals, plastics, ceramics, glass, and composites. However, highly reflective or transparent materials may require special consideration. For optimal results, materials should have sufficient optical contrast against the background. Keyence provides application-specific guidance for challenging materials through their technical support.
Q3: How often does the LS-7601 require calibration, and what's involved?
Calibration frequency depends on usage intensity and environmental conditions, but typically annual calibration is recommended for critical applications. The calibration process involves measuring certified reference standards to verify measurement accuracy across the full measurement range. Many users opt for professional calibration services, though the system includes self-diagnostic features to alert operators to potential accuracy issues between formal calibrations.
