Aggregate Moisture

Instant Moisture Control

Moisture in aggregate materials needs to be considered as it can create potential issues with both equipment and product quality. The IR3000 operates reliably and where other sensors cannot. Whether you work with fine gain to large aggregates in very dry or saturated conditions, the IR3000 is easy to integrate into process lines, conveyors, bins and/or silos.

The IR-3000 takes instant, non-contact measurements of moisture in % dry and % wet measurements. It can regulate moisture content either automatically or manually to suit your needs. Also capable of measuring temperature and other important constituents, the IR-3000 is your best performing option when it comes to material moisture analyzers.

Why Does It Matter?

Moisture measurement is critical in all aspects of the mining process. Thus, mining companies are constantly adjusting moisture to maintain the quality of their product. Advances in real-time sensing, data collection, data analysis and interpretation helps to determine the characteristics of the materials prior to processing. Proper moisture control can provide process efficiency and optimization to the production line. Regular measurements of moisture in minerals remains a necessity for control of drying, thereby reducing treatment costs.

Additionally, small variations and excess moisture in mixes can result clumping affecting quality and consistencies. Too dry of a product can result in excess dust. Measuring moisture prior to crushing can control particle size and provide dust suppression. During the drying stage, in-process measurements ensure optimization and elimination of over drying. This can lead to product that is out of specification, degradation, and an excess of dust.


Unsurpassed in performance, our sensors can accurately measure  moisture within tenths of a percent of most applications


MoistTech sensors withstand the test of time and are low to zero maintenance


Rely on MoistTech’s NIR moisture sensors to never drift or need re-calibration


A moisture measurement system is essential for the production process and in some cases will pay for itself in less than 30 days

Dryer Control

Efficiency is a top of the line priority for manufacturers and the dryer can drain a lot of that. Measuring the moisture before and after the dryer allows the user to optimize the dryer settings to save time and money. A proper moisture control system will pay for itself with the energy savings from the dryer in less than 30 days. Efficiently controlling the dryer within the facility can drastically change the productivity levels.

MoistTech’s Solution

The intelligent pre-processing of the measurement values (300+ per second) allows for smooth average values, adjustable filters. Up to 50 standard calibration curves can be stored in the sensor. Three self-powered analog outputs 4-20mA, allow for the easy connection to control system. MoistTech includes very advanced PC software at no charge with connections via Ethernet or RS232/485.

MoistTech’s NIR moisture sensors are easy to set-up and use which will provide instant and precise measurements due to no constituent losses in handling. We recommend installing sensor(s) in several locations though out the process. A sensor should be installed over the conveyor before the final crusher to enable elimination of impurities, as well as at the exit of the final crusher or dryer, to prevent over drying and dust.

The sensor should be installed several inches above the conveyor belt or screw conveyor so that it can continuously monitor the process and can control the moisture content either manually or automatically in the finished product.

In addition to the IR3000 sensor, we also offer an IP67 rated version as well as an explosion proof version to suit all of our customer’s needs.


Locate the point in the production process in which measuring moisture will be the most crucial and beneficial. Identify how you will use the moisture measurement data for improvements and if it will tie into your PLC.

Remember this could involve more than one installation point!


A closed loop process is achieved by incorporating a moisture measurement system into the manufacturing process. Developing a proactive solution to moisture control will avoid costly downfalls. 


MoistTech’s experts will assess your specific application with lab tests, calibrations and accuracy results to ensure our equipment will peform for you. All of our sensors are pre-calibrated prior to being shipped to create a plug-and-play operation for the end-user.
