SONO-ES with SILO-HT Probe Head - 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 dielectric constants, respectively the moisture content are determined. SONO-ES consists of the measurement transformer SONO-ES and the probe head SILO-ES in a high grade steel casing with a wear-resistant sensor head with ceramic window. An integrated TRIME TDR measuring transducer is installed into the SONO-ES 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 the conductivity of the measured material. The established moisture content, as well as the conductivity, respectively the temperature, can either be uploaded directly into a SPC via two analogue outputs 0(4) ...20 mA or recalled via a serial RS485 interface.
