C A L I B R AT I O N E Q U I P M E N TC A L I B R AT I O N E Q U I P M E N TTESA ® UPD Gage Block Comparator with a 25 mmMeasuring Span• Direct measurement of gage blocks with a variation in nominal length of up to 1 in or 25 mm.– To reduce the number of required reference gage blocks by nearly 80%.• Typical comparative measurement of gage blocks having the same nominal length.– To achieve lower measurement uncertainties due to weakerinfluences of the systematic errors.• Equipped with HEIDENHAIN high-precision incremental probes.• Templates with new concept for positioning the gage blocks (patent pending).– Single or dual template system to provide optimum ease of handling of the gage blocks.• Integrated device for temperature acquisition with high precision.• On-line transfer of the measured length and temperature values.• Computer-aided data processing with all needed corrections included.New TechnicalConcept throughDirect MeasurementTwo mutually opposed, aligned probes connectedin sum measurement also measure thingage blocks reliably as the upper sensor A isable to capture lengths up to 1 in / 25 mm.Displacement of the measuring bolt and activationof the measuring force are both electro-motorized.PT 100 platinum resistances let you capturethe temperature of the two gage blocks, themeasuring table and support.The TESA UP software program processeslength and temperature values as measuredwhile executing and controlling your measurementcycles simultaneously.General✓✓ISO 3650For gage blockswith nominallengths from 0.02 in to4 in / 0.5 mm to 100 mmMeasuringprocedureDirect and comparativemeasurements throughthe transference of thelength of a referencegage block to the gageblock to be measuredIn direct measurement,the nominal length of thetwo gage blocks to becompared may vary upto the size of the measuringspan, i.e. 1 in /25 mmIn comparative measurement,comparison isalways made betweentwo gage blocks of samenominal lengthMeasuring configuration:Two probes with mechanicalcontact with themeasuring face to beprobed are connectedin sum measurement(function +A+B)Measuring pointsOn the reference gageblock: at the center ofthe measuring face(point R). On the gageblock to be measured:at the center (point 1)as well as the four cornersof the measuringface, each lying 2 mmaway from the adjacentfaces (points 2 to 5)The central length l c isdetermined by probingboth points R and 1.For establishing lengthsat any point, themeasurements shall becarried out at pointsR plus 1 to 5The variation in length vis obtained from themeasurements taken atmeasuring points 1 to 5TransportpackingIdentificationnumberK-4Rapp Industrial Sales888 789-7277Calibration certificatesfrom thesupplier (comparator) orthe Swiss Calibr.
