  • Page 25: Swz Probe

    Solitrend MMP20 (Option D) SWZ probe SWZ probe Introduction The SWZ probe uses radar technology at 1 GHz and a probe whose measuring field penetrates deep into the material to be measured. Plastic and liquid fresh concrete with a consistence class of F2 to F6 can be measured by hand easily and directly. An automatic averaging function, with 4 to 10 single measurements taken, ensures a representative measurement of the material mix.

  • Page 27 Solitrend MMP20 (Option D) SWZ probe Please note the following: • There should not be any residue of old concrete around the ceramic on the probe surface. Clean the surface with a wire brush if necessary. • The amount of concrete in the bucket should be at least 3 cm higher than the length of the probe head (<18 cm).
  • Page 28 SWZ probe Solitrend MMP20 (Option D) 8. Repeat the process 4 to 5 times in total  A0040937 In the case of concrete that "sticks", the dark ceramic surface of the probe should be wiped clean before each measurement to ensure that concrete residue "sticking" to the surface of the probe does not falsify the measurement.
  • Page 29 Solitrend MMP20 (Option D) SWZ probe 2. At the edge of the bucket, vertically insert the probe head with the plug-in blade (plastic) fully into the concrete.  A0040931 The plug-in blade ensures that the larger gravel pieces do not "drift away" from the probe head towards the side during the measurement, which can cause inaccuracies.

    Solitrend MMP20 (Option D) Commissioning fresh concrete measurement • When weighing the dry kiln-dried sample, pay attention to the temperature of the kiln- dried sample. When weighing a very hot kiln-dried sample, the upward lift of air streams can produce a considerable error on the scales. For example, when weighing a 4 kg weight, the hot air stream can produce a difference of 30 g, depending on the weighing unit.
