IMKO SONO MIX & VARIO
The IMKO SONO-MIX is a high-precision moisture sensor specifically developed for continuous moisture measurement in concrete mixers. Using patented TRIME® Time Domain Reflectometry (TDR) technology, the SONO-MIX provides accurate, real-time moisture measurement to optimise water dosing, improve mix consistency, and enhance concrete quality.
Designed for ready-mix, precast, and concrete production facilities, the SONO-MIX delivers long-term measurement stability without routine recalibration, even in highly abrasive mixing environments.
Accurate Moisture Control
Installed directly within the mixer, the SONO-MIX continuously measures moisture throughout the mixing process, allowing operators to accurately control the water-to-cement ratio and maintain consistent product quality.
The sensor is suitable for installation in:
Twin-shaft mixers
Planetary mixers
Intensive mixers
Single-shaft mixers
Ribbon blenders
Conveyor and screw conveyor systems
Built for Harsh Environments
Manufactured with a stainless steel body and a highly wear-resistant carbide and ceramic sensor head, the SONO-MIX is engineered to withstand continuous abrasion from aggregates while maintaining measurement accuracy. Automatic compensation for sensor wear eliminates the need for frequent recalibration, reducing maintenance and downtime.
