TESA UPD for direct and comparative measurements

• • Direct measurement of gauge  blocks with a variation in nominal length of up to 25mm or 1 in. - enables the number of required reference gauge blocks to be reduced by nearly 80%.
• • Comparative measurement of reference gauge blocks having a same nominal length - enables lower measurement uncertainties to be achieved due to weaker influences of the systematic errors.
• • Equipped with HEIDENHAIN high-precision incremental probes.
• • Templates with a new concept for positioning the gauge blocks - single or dual template system to provide optimum ease of handling of the gauge blocks.
• • Integrated device for most accurate temperature acquisition.
• • On-line transfer  of both measured length and temperature values.
• • Computer-aided data processing with all needed corrections included.

Direct Measurement of gage blocks with up to 25 mm nominal lengths

• • Permits over 90% of a 122-piece set to be checked using the same reference gauge block. All nominal lengths of the full gauge set being contained within 0,5 and 25 mm, the measuring span is therefore not exceeded
• • Allows the reference gauge set to be reduced by nearly 80% against the ones needed until now.
• • Provides substantial savings in the gauge block supply and recalibration through reduced set compositions.
• • Enables direct measurement of gauge blocks that cannot be compared with other existing gauge blocks due to their unusual nominal lengths.

With Comparative Measurement, the gage blocks are always with equal nominal length 

• • Allows the gauge blocks of same nominal lengths to be measured by comparison as usual.
• • Enhances the measuring conditions, thus permitting all measurements to be taken with a lower uncertainty.
• • Reduces the number of systematic errors through limited length related influences of both the upper probe A and the gauge block to be compared.

Dual template system for the maintenance of your reference gauge blocks - TESA patented
 

• • The simultaneous use of two templates allows you to "rest up" your gauge blocks until you need them.
• • The application of this new concept turns into significant savings in both time and money.
• • During measurement cycles carried out on a routine basis, the distance travelled over the measuring table is reduced by nearly 70 %. This contributes to significant reductions of the risks of damaging and wearing the measurement faces.
• • The double protection of your reference gauge blocks leads to significant cost savings through the reduction if the need for:
  •          – recalibration
  •          – restoration of the measuring faces
  •          – replacement of worn or damaged gauge blocks
  •          – increased downtime (whilst extending the life of your reference gauge blocks)

 

Single template system

• • Using this system your reference gauge blocks are moved together with those to be calibrated during the measurement cycles.
