Precimar ULM 800 L-E Calibration measuring instruments


Large universal length measuring instruments with large direct measuring range are mounted on highly homogeneous rigid granite in a horizontal configuration
X-axis measuring system:

  • Heidenhain incremental, precision length measuring system, 100 mm long in measuring element
  • Heidenhain incremental incident light measuring systems covering the entire length of the base bed and to its right and left
  • Z-axis measuring system: Renishaw incremental, precision length measuring system, 80 mm long
  • Combined measuring instrument for ultra accurate measurements in the range to 100 mm and for measurements in the standard accuracy range
  • Accurate throughout the entire movement range of the measuring element and counter bearing
  • Recommended for measurements of larger measuring objects, but also suitable for measurements of smaller measuring objects
  • Manual operation of measuring spindle
  • Air bearings for smooth manual positioning of measuring element and counter bearing
  • Object height adjustment via pushbuttons (also positioning of predefined increment)
  • Computer provided temperature measurement with 3 sensors
  • Computer-aided instrument zero point stabilizing and correction of systematic instrument errors (CAA)
  • Constant measuring force over the entire measuring spindle setting range
  • Computer-aided correction of temperature and measuring force influences
  • Large object table with precision guidance in the Z direction and a loading capacity of 25 kg
  • Mahr 828 WIN measuring and evaluation software runs under MS Windows®
  • Optional use of measuring axis extensions
  • Inner thread measurement supported by automatic Z positioning
