Thanks to its robust design, the new SONO-VARIO LD moisture probe is ideal for installation in containers, material hoppers, conveyor belts and screw conveyors.

Bulk solids experts confirm: TRIME® technology offers considerable advantages over microwave technology and capacitive measuring methods when it comes to material moisture measurement. For example, temperature fluctuations, conductivity and particle size distributions have no influence on the moisture measurement. Its secret: the use of state-of-the-art TRIME® radar technology (Time Domain Reflectometry).
Using an electromagnetic TDR pulse with a 1 GHz frequency, SONO probes measure the water content precisely up to material saturation and beyond. Up to 100% water content can be measured. This even makes it possible to measure solids (e.g. 0..10% solids content) in liquids.
No further analysers are required. Signal processing and evaluation with intelligent filter algorithms takes place directly in the probe. The measuring head is very robust and wear-resistant. If there is increased wear, the probe head can be easily replaced. The SONO-VARIO LD also has a special function for fluidised bed dryers to control the air flow.

For high temperature applications of up to 150°C, the SONO-VARIO LD is also available in a special version with the SONO-ES.
New innovative technologies should be associated with improvements as well as lower investment and follow-up costs. The demands on the quality of products of all kinds are becoming ever higher. The modern and revolutionary TRIME® method opens a new chapter in material moisture measurement.
