Mahr Metrology - Precimar ULM L-E Precision Length Measuring Systems Dimensional Metrology System

Add Quotation

Universal length measuring instruments with laser measuring system are mounted on highly homogeneous rigid granite in a horizontal configuration
X-axis measuring system: interferential laser measuring system, 525 or 1115 mm long
Z-axis measuring system: Renishaw incremental, precision length measuring system, 80 mm long
  • High end length measuring instrument with large direct measuring range
  • Compliant with Ernst Abbe's comparator principle
  • Manual operation of measuring spindle
  • Air bearings for smooth manual positioning of measuring element (with laser reflector) and counter element
  • Object table height adjustment via pushbuttons (also positioning of predefined increment)
  • Laser correction with respect to environmental influences: temperature, air pressure (humidity optional)
  • Separate laser generator outside the measuring instrument, fed via optical cable, and laser beam cover
  • Computer-aided instrument zero point stabilizing and correction of systematic instrument errors (CAA)
  • Computer provided temperature measurement and computer-aided correction of temperature and measuring force influences
  • Constant measuring force over the entire measuring spindle setting range
  • Large object table with precision guidance in the Z direction and a loading capacity of 25 kg
  • Automatic reversing point detection with static and dynamic adoption of measuring values
  • Highly flexible within the application range (can be used for measuring both miniature and large measuring objects)
  • Mahr 828 WIN measuring and evaluation software and MS Windows®
  • Inner thread measurement supported by automatic Z positioning
