RayDex hr
is anagolous in design to the RayDex cr, allows however though the lager rotor diameter even higher repeatabilities.
This version allows axial penetration depths (e.g. into a cylinder) of nearly 150 mm.
Applications of all RayDex Sensors:
- Within measurement stations for individual objects in production and / or in a laboratory
- Attached to a robot, to conduct interior measurements for e.g.
- Mounted to a Coordinate Measurement Machine (CMM), once accuracy and speed are crucial factors
