TRIME-PICO IPH/T3

A high frequency 1GHz TDR impulse is created, runs along the metalic half shells und establishes an electromagnetic field around the conductors and with that the TRIME tube probe. At the end of the conductors the impulse is reflected completely and goes back to the source. The time of the impulse (10ps…2ns) is directly connected to the volumetric water content of the measured medium via the dielectric constant. Already after two to three seconds the measured moisture value is shown. The effective penetration depth of the measuring field comprises around 15cm. The measuring field is most sensitive directly at the surface of the tube, the sensitivity decreases exponentially with a growing distance.
