A concrete factory in Houston, Texas, needed an on-line moisture sensor to be installed in their fresh concrete mixer with high measurement accuracy to minimize recipe errors. We installed our SONO-MIX moisture sensor that was integrated to their SCADA system for real-time averaged moisture readings at a rate of 4 per second.

The SONO-MIX Mixer Probe consists of a high grade steel casing with a removable wear-resistant sensor head made of hardened steel and ceramic. The sensor enables correlation of recipe parameters such as cement content and slump of fresh concrete. Even in the event of abrasion at the probe head of a SONO probe, the automatic measurement compensation enables significantly longer operating periods without the necessity of re-calibration. A built-in temperature sensor in the moisture probe enables the sensor to carry out temperature compensation for the measured material.
