Specialty
SPEETEC closes the gap between tactile measuring wheel systems and complex laser Doppler sensors – and is suitable for almost all surfaces and objects thanks to the non-contact measurement that uses no measuring elements. This opens up new fields of application in motion monitoring.NCV50B is the preferred choice for retrofitting and use in end-customer applications where easy mounting is important. The NCV50B achieves a very high measurement accuracy with large mounting tolerances, which allows quick and easy mounting without a reference measurement or calibration.Non-contact measurement on moving objects without measuring elements.Class 1 laser
