LN3000 — Lump and Neckdown Detector Series

High-precision, Three-Axis Flaw Detection For Continuous Quality Measuring.

The LN Series offers high-performance gauges, precisely detecting short-term faults in a product diameter,  using three optical axes spaced at 60-degree intervals to deliver a higher degree of coverage around the product’s circumference to instantly detect sudden changes in the surface.

LN SERIES BROCHURE
  • Capture important flaw information relating to height, length, number and location.
  • Visualise fault and gauge updates with colour-coded status indicators.
  • Performs in the harshest environments with rugged and environmentally sealed housing designed to IP65 standards, thus avoiding light and dust contamination. 
  • Built-in communication for easy integration.
  • Monitor gauge performance with built-in diagnostics, ensuring proper strength for each axis and maximising uptime with clean optics. 
  • Synchronise with reel changes to clear system data and initialise for the next reel.

Made to Measure Support Every Step of the Way

We believe our customers should deal with an expert from the point of enquiry to project completion. Therefore, we will appoint you a product specialist, so you have continuity and a single point of contact. They will be your guide, help identify the best solution for your particular application and be with you through to successful implementation.
