SONO-MIX - User Manual

The TDR technology (Time-Domain-Reflectometry) is a radar-based dielectric measuring procedure at which the transit times of electromagnetic pulses for the measurement of dielectricity constants, respectively the moisture content are determined. The SONO-MIX Mixer Probe consists of a high grade steel casing with a removable wear-resistant sensor head made of hardened steel and ceramic. An integrated TRIME TDR measuring transducer is installed into the casing. A high frequency TDR pulse (1GHz), passes along wave guides and generates an electro-magnetic field around these guides and herewith also in the material surrounding the probe. Using a new patented measuring method, IMKO has achieved to measure the transit time of this pulse with a resolution of 1 picosecond (1x10-12), consequently determine the moisture and to provide information in regard to the concrete composition.
