Model Sono-Ex GS1 - Moisture Probe - Manual

The TDR technology (Time Domain Reflectometry) is based on a radar-based dielectric measurement method in which the transit times of electromagnetic pulses for measuring the dielectric constant or the water content are determined. The SONO-Ex GS1 humidity measuring system consists of a measuring unit and an external measuring probe. The external measuring probe consists of an aluminum housing with a window made of PEEK. The measuring unit is a stainless-steel housing with an integrated TRIME TDR transmitter. The high-frequency TDR pulse (1 GHz) generated in the TRIME transmitter runs along waveguides and builds up an electromagnetic field around these conductors and therefore in the material around the probe. With the patented measuring method, the transit time of this pulse is measured with a resolution of less than a picosecond (1x10-12) in order to determine humidity and conductivity.
