Pug Moisture

Moisture Correlates Quality

Pug is a product that is produced thru a pugmill (sometimes spelled as pug mill), a machine in which materials are simultaneously ground and mixed with a liquid. Industrial applications are found in bricks, pottery, cement and some parts of the concrete and asphalt mixing processes. In ceramics pug mills, or commonly known just as “pugs”, are not used to grind or mix, but rather they extrude clay bodies prior to shaping processes.

Having the correct pug moisture level has become a critical component during the production process. Being such a porous material, pug can easily become either too wet or dry wasting the manufacturer’s time and money.

Our sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements are pre-set at the factory. Typical accuracy is about ±0.1% moisture and typical analog range is 0-10% moisture and up to as much as 40%, subject to application. The outputs can be adjusted to optimize PLC or recording requirements.

Measure Moisture in Real Time


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

Installation Tips

By installing the MoistTech pug moisture sensor in the processing area, the user continuously monitors the manufacturing process with the ability to control the pug moisture content either manually or automatically.

The sensor should be installed over the conveyor transporting the pug, several inches above the belt, screw conveyor or any area where the material can be viewed. In the installations of spray or fluid bed dryer’s, optical windows or sampling systems can be provided.

    • Increased Equipment Life
    • Lower Energy Costs with Proper Dryer Control
    • Reduced Start-up Times
    • Less Waste & Downtime

MoistTech’s Diamond Standard Solution

MoistTech has studied moisture and its applications in manufacturing for over 40 years. That’s why we’re confident our moisture analyzers are a step above the rest. We’re constantly working to develop the latest, most advanced moisture testing technology—which is how the IR-3000 came about.

We’ve combined our decades of experience and knowledge with feedback from our industry partners to create a moisture sensor capable of taking instant, non-contact measurements of moisture, temperature, and other vital levels with the utmost accuracy. When it comes to moisture sensors, the IR-3000 is the most advanced system available.


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.


We offer service and support throughout the world for our moisture measurement sensors and would be happy to connect you with a rep in your area. Contact us today for more information!

Understand the Process

Using the IR-3000 drastically cuts production costs. It is energy efficient, low maintenance, and decreases startup and down times. Over dried product causes waste; so does product that is too moist. With the IR-3000, these problems will no longer be an issue.

Using the IR-3000, you’ll save money throughout the entire production process, while making the best quality product at the same time. With MoistTech, you don’t need to compromise.
