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
