Non-contact Speed & Length Laser Measurement

The new, smart and uniquely compact Laser Doppler Speed and Length Sensor – SL and SLR that sets new standards in non-contact speed and length measurement of moving objects and materials in industrial applications.

Designed to replace cumbersome, inaccurate and high-wear contact wheel encoders that are prone to excessive measurement errors due to slippage, vibration, wear and dirt, resulting in product give-away and quality issues.

As the second generation series, the SL and SLR mini are designed for industrial applications and material processing lines; compatible with almost all moving materials including web, wire, plate and sheet. Measurement and control of length, speed, differential speed and elongation on paper, plastic film, foil, non-woven, rubber and many more materials. 

The non-contact laser technology provides an industry leading accuracy of +/-0.05% without need to ever re-calibrate due to wear. The internal measurement rate is 200kHz with one measurement output every 20 microseconds. Communication is via Ethernet, RS-232, Wifi or bus options. Plus a complete range of installation accessories including anti-vibration mounts, display units, temperature and dust control.

Full technical support on the sensor and laser safety is available from TTS Systems
