AquaSense 2280D microwave moisture meter builds on past successes to give you a totally new, reliable moisture sensor that stands up to the rough environment of concrete plants.
AquaSense 2280D is suitable for many different applications for moisture measurement, from aggregate moisture to powdered and granular products.
AquaSense 2280D is a moisture probe or sensor, for use in sand, powders and granulated materials. Its hard ceramic faceplate is rugged and hard wearing, giving 10 to 20 years service in concrete applications.
AquaSense 2280D uses a Windows Graphic User Interface (GUI) for setup and moisture calibration. Here’s how it works:
Hardware for use with AquaSense and AquaMix.
Why do we need moisture measurement in the sand bins? What is the effect on the concrete? Why do we still get variations in slump or moisture? What is a mixer water dosing system? What is a slump meter? Answers to these questions and more below.
Can I take a sensor calibrated for sand and use it on other materials? Can I use AquaSense 2280D’s sampling feature for on-the-fly batch correction? Which is the best output choice, 0-10 volts or 4-20 mA? This page answers your Moisture, Frequently Asked Questions and others.
AquaSense Applications and Examples
Although Aquasense 2280D is new, it’s predecessor, RadarTron, has been successfully used to measure moisture of sand and aggregates in concrete and asphalt plants. Also coal, ironstone and similar minerals, foundry sand, clay, lime and bentonite, powdered and crystalline chemicals, food and animal food products. Examples of these are powdered starch, corn in grain dryers, dog and cattle food, and many other products. Call us to find out if your product has been tested. If it hasn’t, you can send us a pail for a full test. Talk to us about arrangements for a demo or trial in your plant.
Customers and Applications
Twin Valleys Precast, near Edmonton Alberta,use two AquaSense 2280D sensors in their sand bins . . . Read more
Installed in 2014, they continuously correct the dry material weights for batching on a daily basis, producing concrete for prestressed oil pump bases and wall panels.
Sintra, near Montreal, have used several Scale-Tron aggregate moisture sensors for many years in asphalt production, adjusting the dryer to optimize efficiency. As a result, they have lowered energy costs.
Greg Roache of Gainey’s Precast, near New Orleans, installed AquaSense 2280D with his BatchTron control system in 2016 and it is in daily use.

Smart Sand, of Tomah WI have been using several AquaSense 2280D moisture sensors since summer 2017 . . . Read more
to measure the moisture of quarried fracking sand before it runs through the dryer. The sensor modulates the burner to dry the sand. Similarly to Sintra, they are minimizing their use of energy as a result.
PLB International, near Montreal, has used Scale-Tron moisture sensors for many years in the manufacture of dog food.
AquaSense 2280D measures the moisture of sand, mineral ores, coal, clays, starch, animal feed, sludge and many other materials. Contact us about your application.

Connection to Controller
You can easily connect several AquaSense 2280D probes to a computer or PLC . . . Read more
Feed the standard analog output into the analog input of most batching controllers and PLCs. An RS232 port allows you to connect them one at a time for setup or calibration. Connect several sensors by serial RS485 connection with a single cable, eliminating the extra cable runs as a result. This connection is industry-standard and compatible with almost all batching controllers, PLCs and computers. Alternatively, the AquaSense sensor handles Modbus commands for use in Scada systems.
