Sauter LB 300-2. Distance Meter, 300 mm Range, 3 % Accuracy

Kern Digital length measuring device measures distance directly in machines or sites with RS-232 interface.

• Digital sliding calliper with a superior precision even at high operation speed;• Easy mounting to machine tools, conveyer, test stands etc.;• Zeroing,pre-added and pre-reduced length as well as switching the unit can be done manually;• Data interface RS-232, standard

Surface Finish

Any machined component has a surface geometry which consists of three basic elements:

Form or Curvature - Whether the surface has irregular bumps or dimensional changes

Waviness and roughness are traditionally the most difficult elements to measure when comparing surface finish, however, they have a radical effect on the performance of the finished component. Variations will cause aesthetic appearance changes, component wear variations, oil retention variation etc. Many manufacturers therefore specify a range of roughness values which their components should be manufactured to, often expressed as: Ra, Rq (RMS), RzDIN, Ry, Sm,mm.
