Bedford, NH – The Metrology Engineering Team is pleased to announce the next generation of high-precision filament and wire inspection with the release of the CDM90 STS Continuous Diameter Measurement Platform. This turnkey system provides high-speed, real-time diameter measurement of filaments and wires ensuring superior accuracy and production consistency for in-line manufacturing environments.

Fine wire transport and multi-pulley tension divider eliminates distortion, keeping the diameter consistent
The CDM90 spool-to-spool platform integrates two state-of-the-art Keyence LS-9006M High-Speed Optical Micrometers positioned at 90-degree angles. This configuration enables precise diameter measurement within a range of 0.04 mm to 1 mm (0.0012” to 0.039”), delivering exceptional accuracy for critical manufacturing applications.
“Our unique design meets the growing demand for precision diameter measurement in filament and wire processing,” said Todd Lizotte, CEO and co-founder of Bold Laser Automation. “By combining advanced optical micrometry with real-time data monitoring, we are able to achieve consistent product quality while improving operational efficiency.”
Key Features and Benefits of the CDM90 STS
High-Precision Measurement:
- Dual Keyence LS-9006M Optical Micrometers measure filament or wire diameters with unmatched accuracy.
- V-groove wheel transfer through the sensors ensures stable and consistent readings.
Advanced Handling and Tensioning:
- Integrated spool-to-spool module with adjustable tensioning allows smooth despooling and respooling of filaments.

Ergonomically designed for efficiency, the operator can easily observe the wire-handling system in action, ensuring repeatable wire diameter measurements
- Precision guide pulleys, weighted dancer accumulators, and controlled tensioning ensure stability during inspection and wind-up.
Robust System Structure:
- Mounted on an extruded aluminum T-slot frame for stability and ease of maintenance.
- Can be mounted in various configurations for filament manufacturing lines, thread weaving and spinning lines, or as a desktop wind-up system for dispensing products for resale.
Smart Data Acquisition and Monitoring:
- Onboard computer with a 14-inch monitor (touchscreen or mouse-operated) for real-time data monitoring and logging.
- Integrated data acquisition system consolidates sensor data, with optional wheel encoder input for enhanced accuracy.
- All data is logged, time-stamped, and saved locally on a 1TB drive, with optional remote backup capability.
- Optional MES integration for connecting metrology data to ERP systems, enabling batch and lot inspection.
Plug-and-Play Installation:
- Operates on standard 110/220 VAC single-phase power with UL, NFPA 79, and OSHA compliance.
- Simple facility requirements for seamless integration into existing production lines.
“For woven products, the CDM90 platform ensures precise filament transfer without distortion or elongation, maintaining a consistent diameter spool to spool,” explained Lizotte.
