Combined Applications for Dimensional Check

Measurement Solution based on combined single Gauges

ELOVIS sensors are designed to be combined to offer complete measurement solutions from a single source. Typical combined dimensional control applications include e.g. systems for length measurement in combination with systems for width and thickness measurement. Both length measuring gauge types, either the laser-encoder family μSPEED or the discrete part length measuring systems of the SLM family can be used here. In addition to the width measurement, height and thickness measurement, other parameters, such as angularity, parallelism or the diagonal measure can be determined. ELOVIS gauges of the μMETER-X family are used here. Non-contact dimensional control usually takes place during the ongoing production process during material transportation. The measurement serves for the inline monitoring of the dimensions for compliance with the product tolerances and documentation of the delivery condition and, if applicable, the feedback to the process and machine control. All optical ELOVIS sensors are maintenance-free, permanently calibrated and measure largely independent of material. Combined measuring systems are available for the measurement of profiles, tubes, plates, beams as well as webs and tapes made of different materials.

Combined applications for dimensional control: The non-contact ELOVIS measuring instruments for length, width, height and thickness measurement as well as squareness and parallelism are listed here. The advantages resulting from the use of these measuring devices are named afterwards.

ELOVIS measurement solutions for non-contact control of length, width, height, angularity, … by combining individual sensors:

  • Length measurement → SLM
  • Width, height and diameter measuring system → µMETER-X
  • Light grid, cross-section light scanner, light curtain, transmitted light measuring grid, optical caliper, automation light grid → µMETER
  • Vision sensor, camera system, matrix and line scan camera → μVIS

Measurement advantages with non-contact ELOVIS measuring equipment:

  • Wear-free, maintenance-free, permanently accurate ⇒ no maintenance costs, minimum operating costs
  • Self-monitoring ⇒ Warning in case of defect
  • Suitable for high product speeds ⇒ prepared for the future
  • Material-independent measurement ⇒ Measuring principle largely eliminates the influence of material variation
  • Long life LED components ⇒ Long measuring system life
  • Measurement of all parts ⇒ 100% documentation and traceability of measurement results
  • Traceable, calibratable, conformity assessable ⇒ legal certainty

Combined applications for dimensional control: The list shows the applications for non-contact ELOVIS measuring devices for the measurement of a wide variety of measured variables.

Combined Tactile Measurements Applications: Typical traditional and mostly touching measuring instruments for length, width, height and diameter measurement as well as squareness and parallelism are listed here. The measuring problems resulting from the use of these measuring devices are also named.

Dimensional control for length, width, height, angularity – traditionally tactile:

  • Meter stick, caliper, tape measure
  • Measuring stop with steel ruler
  • Manual sampling

Measurement problems with traditional measuring equipment:

  • Material movement too fast (henceforth only random checks)
  • Measurement and measurement accuracy depending on the operator
  • Errors by visual reading and manually entering the results in lists

Consequences of measurement problems:

  • High staff costs
  • Operator-dependent measurement spread
  • Complaints due to width / height error
  • Dimensional additions to avoid complaints
  • Big effort through manual sample testing after  error message
  • Big effort in post-processing of parts
  • Lack of traceability

Combined dimensional control applications: Combined non-contact ELOVIS measuring devices are used in the following industrial sectors.

Semi-finished goods production (widths, diameters):

  • Plastic industry and extrusion (profile, hose, pipe, sealing industry, …)
  • Carpet and flooring industry (roll width, web width, …)
  • Metal industry (sheets, blanks, tubes, profiles, bolts, rods, bars, …)
  • Furniture industry (furniture panels, doors, window frames, …)
  • Paper and board industry (hubs, cores, width in transverse movement, roll diameter during longitudinal movement)

Construction industry (panel widths, thicknesses):

  • Wood industry (piece wood, boards, KVH, beams …)
  • Drywall construction (plasterboard, chipboard, MDF boards, HDF boards, OSB boards
  • Insulation industry (insulation panels, fiberglass panels, Rockwool panels, …)

Packaging / transport industry (package dimensions):

  • Packaging material, packaging material (boxes, packages, pallets, …)
