Composition-linked near-infrared moisture transmitter automatic water valve control device
This near-infrared online moisture meter is an industrial-grade real-time detection device customized for the ready-mixed concrete industry, primarily used for online monitoring of surface free moisture in aggregates such as manufactured sand, river sand, and crushed stone on conveyor belts at mixing stations. Traditional manual sampling and oven-drying detection methods have long intervals and poor sample representativeness; slight fluctuations in aggregate moisture content can alter the concrete water-to-binder ratio, causing quality issues such as unstable slump, bleeding and segregation, substandard strength, and pump pipe blockage. This device adopts a non-contact optical detection method, enabling rapid moisture measurement during dynamic material conveyance on the belt, and transmits moisture content data in real time to the mixing station's PLC batching system.
