EPP Gauge block Calibration System

High-precision gauge block calibration system:

Measuring device with two aligned probes
The LM 20 laser interferometric probe guarantees high measurement accuracy and linearity.
Only 15 gauge blocks required to calibrate a 122-piece set of gauge blocks
Cost savings thanks to low recalibration effort
Measurement time savings thanks to user-guided measurement sequence
Ability to calibrate unusual nominal dimensions and materials
High linearity over the entire measuring range
Constant probe force over the entire measuring range
Correction for sample and normal temperature
Material temperature sensor (4-piece option)
Windows PC software
The EPP gauge block calibration system uses an LM 20 laser interferometric probe as the top measurement probe. It has a measuring range of 20 mm and a resolution of 1 nm. The Physikalisch-Technische Bundesanstalt Braunschweig has determined a measurement error of less than 10 nm for this probe when calibrating gauge blocks. This means that the number of shims required can be reduced to 15 for a 122-piece shim set, in line with a PTB recommendation.
A calibration procedure is used to determine and correct linear errors in the gauge block tester (misalignment, probe inclination, temperature influences). Convenient operation of the gauge block testing station, as well as correction, evaluation and editing of the measured values, is carried out via a PC using the “InfasGAUGE” software (parallel calibration of gauge blocks).
