Inline speed & length measurement with laser precision 

Precise speed and length measurements are critical for controlling the production of continuous materials, sheet materials and piece goods. ProSpeed® – the next generation LSV Laser Surface Velocimeters – optimize production processes by providing reliable measurements and increase the output worldwide in the metals, cable and converting industries. 

ProSpeed® LSV-1100 Laser Surface Velocimeters determine length and speed in forward direction reliably even in harsh production environments.


  • Reliable measurement of forward motion
  • Easy process integration with long working distances up to 1.5 m
  • Outstanding measurement depth-of-field up to 140 mm
  • Transparency thanks to the enhanced connectivity (web interface, Ethernet, field bus protocols)
  • Multi user access (3 via Ethernet + 1 serial)

Visible laser for easy alignment

  • Robust sensor technology (IP 66, 67)
  • Accessories like thermo-protective housing, air wipe, air amplifier, cooling plate, beam deflection unit etc.

Compact, reliable, cost-efficient

ProSpeed® LSV-1100 Laser Surface Velocimeters measure length and speed reliably even under harsh production conditions with working distances up to 1.5 m. Due to the non-contact measurement principle, these laser sensors eliminate common problems of traditional contact-wheel measurement methods such as damage to delicate surfaces, slippage and thermal expansion and work on almost any surface.

The TPH thermo-protective housing offers additional protection especially for really challenging environments. Application-optimized accessories such as air wipe and air amplifier, cooling plate, beam deflection unit and more enable customized sensor solutions with easy in-line integration.

Sensor integration with enhanced connectivity

The enhanced connectivity concept of the ProSpeed® LSV sensor generation grants access to configuration and process data anywhere and anytime. Enhance your flexibility, enabling direct feedback to machines on behalf of monitoring data through an optional touch display. Parametrize the sensor via web interface with ease and benefit from data access with Ethernet and serial interface for up to four users. For automated PLC-controlled processes, use the integrated PROFINET and EtherNet/IP interfaces which makes sensor integration into any production control systems as smoot and easy.
