Linear speed and length sensor LaserSpeed Pro

laserdigital outputwith length function

Overview The LaserSpeed Pro gauge by Nordson is a non-contact Laser Doppler Velocimetry (LDV) system for precision length and speed measurement of moving surfaces. It delivers typical accuracy of ±0.03% and repeatability of ±0.02% with no moving parts, factory calibration and Ethernet connectivity for Industry 4.0 integration. Rugged housings and multiple standoff options adapt the gauge to demanding industrial lines.

Applications

• Continuous length measurement
• Speed measurement (forward/reverse and true zero)
• Differential speed control
• Cut-to-length control
• Tension control
• Discrete product measurement
• Product positioning
• Printing and coating process control

Features & Benefits

• Direct replacement for tachometers and rotary encoders
• Non-contact measurement: no slippage, no marking; works on all materials, shapes, colors and textures
• Bi-directional and true-zero speed measurement
• Factory-calibrated; no moving parts for low maintenance
• Industry 4.0 ready with Ethernet and industrial communication options
• Options for harsh environments: stainless housings, air purge windows, sealed enclosures

Models & Standoffs

• Model suffixes: -401 (LS 4500 only), -403, -406, -410
• Standoff distances: -401 = 100 mm | -403 = 300 mm | -406 = 600 mm | -410 = 1000 mm
• Speed ranges vary by series (LS Pro 4500 / 8500 / 9500) — ranges from ~0.2 m/min up to ±12000 m/min depending on model/configuration
• Measurement depth of field: approx. 15 mm, 35 mm, 50 mm or 100 mm depending on suffix

Options & Configurations

• 8500X / 9500X: stainless-steel housing with integrated air purge for steam, mist and spray environments
• 8500E / 9500E: double-sealed environmental housings for hot/aggressive sites
• 8500-C / 9500-C: C-frame mounting kit for combined thickness and speed/length measurement (includes gauge, mounting rail, right-angle mirror and safety cover)
