Non-contact Speed & Length Laser Measurement

All Proton Products Speed & Length Gauges:

Provide high-speed, non-contact, solid-state laser doppler speed and length measurement with no slippage, drift or mechanical wear and greatly reduced maintenance compared with contact wheel / roller systems.
Are accurate to better than 0.05% and repeatable to better than 0.02% with UKAS-traceable calibration.
Are housed in rugged enclosures to survive harsh industrial environments.
Are available with industry-standard communications interfaces fitted either as standard or as an option.
Are available in stand-off distances and depths-of-field to suit applications as required.
