Non-contact speed and length measurement

The new sensors are designed to replace cumbersome contact wheel encoders which TTS Systems says are prone to excessive measurement errors due to slippage, vibration, wear and dirt, which can result in product give-away and quality issues.

The second generation series (SL and SLR mini) are designed for industrial applications and material processing lines. They are compatible with almost all moving materials, including web, wire, plate and sheet, and can be used for 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 is said to provide an industry leading accuracy of ±0.05% without the 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. Installation accessories include anti-vibration mounts, display units, temperature and dust control.
