Moisture Frequently Asked Questions
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.
The moisture sensor for operation in concrete mixers.
The control system for sensing water in the mixer and adding the right amount.
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.
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.
Is the AquaSense 2280D sensor ready to use when I get it? I hear that your sensor is harder to calibrate than others. Is this true? 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 analog output choice, 0-10 volts or 4-20 mA? Is AquaSense 2280D’s digital connection compatible with my batching controller? My material is hot. Can I use AquaSense 2280D in this case? Can I install AquaSense 2280D on a conveyor? How can I view the moisture in several bins simultaneously? How can I monitor moisture in a single bin that holds several different materials from time to time? Why do my sensors burn out for no apparent reason?
