  • Page 4: Instrument Description Sono-Mix Mini

    SONO-MIX MINI accurately measures both in the dry mixture and in the wet mixture. A "dry mixture" can e.g. be mixed with residual water varying solids content so that the water content to 70% target is met.

  • Page 5: Mode Of Operation

    The delivery scope of the SONO-MIX MINI includes suited parameters for the averaging period and a universally applicable filter function deployable for currently usual applications. The time for the average value accumulation, as well as various filter functions, can be adjusted for special applications.

    Normally this is related with high efforts in laboratory works. SONO probes offer the possibility to set special temperature compensation parameters t0 to t5 for every calibration curve Cal1 of Cal15 (see chapter “Selection of the individual calibration curve”). Please contact IMKO should you need any assistance in this area.

    2.3. Calibration of SONO-MIX MINI in a mixing plant SONO-MIX MINI is delivered with a raw calibration function which is far higher than the real moisture values (kiln dried values) of a sand/gravel or fresh concrete mixture. The reason is that SONO-MIX use a powerful modified filter algorithm, which would work incorrect at Zero-values (division by zero results in infinite).
