LN3000 - Lump and Neckdown Gauge
Quickly, reliably detect and locate product flaws on wire, cable, and tube, such as lump and neckdowns, before they become costly production problems to ensure maximum quality control.
Overview
The LN Series is Nordson's latest solution in fault detection. These high-performance lump & neck gauges provide more precise detection of short-term faults in the product diameter at higher line speeds than two-axis systems. The new LN Series uses 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. Applications include extruded wire & cable, insulated and jacketed wire & cable, extruded plastic and rubber hose, pipe, & tube, and other extruded products of similar profile or configuration.
Features & Benefits
- Capture, track, and report critical data – capture important flaw process information and effectively report on height, length, number, and location.
- Built-in communications for easy integration – RS232, telnet, EtherNet/IP, Ethernet, DeviceNet, Profibus, and Profinet.
- Built-in diagnostics – ensure proper signal strength for each axis, maximize uptime, and keep a close eye on other gauge performance.
- Visualize fault and gauge statuses – alert operators via color-coded status indicators.
- Synchronize with reel changes – accept signals from reel changers to clear system data and initialize for the next reel.
- Performs in toughest environments – Sealed metal housing engineered to minimize light and dust contamination.
- User-friendly operator interface – no need to mount an external display.
