SONO-MIX: The toughest mixer probe for the measurement of concrete moisture


Moisture measurement in concrete
The accurate low-cost solution for:

  • Construction Industry
  • Bulk Material Handling
  • Higher safety at the production of fresh concrete due to the precise measurement of the moisture as well as the radar-based conductance (RbC – Radar based Conductance) up to 50dS/m. RbC enables conclusions regarding further parameters of the material recipe such as the cement content and the slope of fresh concrete with the effect of a more reliable quality control and higher cost-effectiveness because recipe errors are prevented.
  • The novel and extremly robust sensor head,
    made of a solid carbide plate and a rectangular ceramic window, offers an unknown long service life. It is fastened with 4 screws and can easily be exchanged.
  • Even in the event of abrasion at the probe head, the automatic measurement compensation enables significantly longer operating periods without the necessity of recalibration.
  • SONO-MIX can even measure steel fiber concrete.
  • High accuarcy even in the wet mixture and thus the possibility to dose the water addition very precise by using recycled water.
  • Highest Reliability: In comparison to Microwave probes, SONO probes provide accurate measurement values even when aggregates are exposed to steam in winter and where the sand and the gravel feature differing grain sizes.
  • The intelligent pre-processing of the measurement values featuring smooth mean value accumulation, adjustable filters, and up to 15 calibration curves for the calibration which is already conducted in the sensor itself. Usually, external evaluation devices are not required.
  • Two variably adjustable analogue outputs 0(4)...20mA allow for the easy connection to any currently existing control system.
  • A RS485 interface
    enables the network operation of the sensor. It already contains a data bus protocol for the connection of several SONO sensors. The connection of the sensor to industrial buses such as Profibus, Ethernet, etc. is possible via optional external modules (available upon request).
