The SonoVario-Xtrem sensor measures on-line moisture of aggregates up to 1-1/4-in. with accuracy, repeatability and reliability. Cable Radar technology, positioning the sensor in direct contact with material being measured, allows installation under hopper gates to log each batch’s sand and stone moisture. Sono-Vario-Xtrem sensors are delivered with 15 pre-installed, linear material calibrations for all standard construction materials. Free interface software supports calibration and simulation of the analog interface integration, plus setting and parameter adjustment. An auto-zero function keeps moisture readings accurate over the long term, even with highly abrasive limestone.
