The non-contact encoder ProSpeed®
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 Velocimeter – optimizes production processes by providing reliable measurements and increases output worldwide in the metals, cable, and converting industries.
The ProSpeed® LSV-2100 optical sensor determines the direction of motion and standstill conditions with laser precision.

Achieve far more in your production process
ProSpeed® LSV-2100 optical sensors measure length and speed reliably even under harsh production conditions, with large working distances up to 3 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 while working on almost any surface.
The TPH thermo-protective housing offers additional protection especially for particularly challenging environments. Application-optimized accessories such as air wipe and air amplifier, cooling plate, beam deflection unit, and more enable customized sensor solutions for easy in-line integration.







Simplified sensor integration with enhanced connectivity
The enhanced connectivity concept of the ProSpeed® LSV sensor generation grants access to configuration and process data anytime, anywhere. Enhance your flexibility, enabling direct feedback to machines based on monitoring data through an optional touch display. Parameterize the sensor via web interface with ease and benefit from data access via Ethernet and serial interfaces 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 smooth and easy as possible.
