HIGH-PRECISION MEASUREMENT OF STRAIN GAUGE TRANSDUCERS AT THE PHYSICAL LIMIT WITHOUT ANY CALIBRATION INTERRUPTIONS |

- Abstract:
- The maximum resolution when measuring transducers, which operate on the strain gage principle, is physically limited. Possible sources of errors and their compensation to achieve the high accuracy class of 0.0005 (5 ppm) are shown. In addition to the actual extraordinary high measuring accuracy and long term stability, for the new precision instrument DMP41 the autocalibration cycles could also have been omitted. An innovative method allows to measure for the first time in this accuracy class without any interruptions caused by an auto-calibration.
