 Notes

  1. For dry and high-flow concrete-mixing machines, water content does not exceed 14%; therefore maximum moisture value of 20% (ratio of water weight to the total weight of the concrete mix) is set in the calibration characteristics for moisture meters installed in concrete-mixing machines.
  2. Calculating by the following mathematical equations (formulae) gives the following values ​​of the absolute error Δ:
    Moisture range W Acceptable absolute error limits Δ
    up to 10%

    10…20%

    20…50%

    50…100%
    0,5%

    1%

    2,5%

    5%
  3. Using the supplied software by the method described in the operating manual, the user can adjust moisture meter calibration data for the enhancement of moisture measurement temperature range.
  4. The required cable length between the sensor and the electronic unit is agreed when ordering.
