Frac Sand Moisture

Intentional Avoidance of Quality Issues

Generally frac sand is extracted, cleaned, screened and kept in piles for supply of numerous grades. The sand requires drying to a specific moisture content to prepare it to be sold or additionally processed to include a resin or alcohol coating.

MoistTech Corp. provides a top of the line solution with their IR3000 series moisture and control gauges. Utilizing the 3000 collection of sensors allows the rapid control of the drying system, which results in quality spec sand without wasting time, energy and money. Our top quality sensors are developed for tough installations where competing sensors often cannot perform. Straightforward plug-and-play operation allows for sensor mounting 4”-12” above the moving product, producing live moisture readings with a repeatability of 0.1% or better.

Standard outputs allow for a simple digital display or full PLC integration with many options in between. The 3000 Series sensors are designed as a one-time calibration with zero maintenance, allowing operating personnel to make immediate adjustments to the line.

Benefits That are Immediately Seen

Benefits of the MoistTech 3000 series sensor include a user-friendly design, durable enclosure (NEMA4 IP65 or Stainless Steel IP67) for harsh process environments, lower operating costs, more efficiency and consistent drying.

Unaffected by material variants like particle sizes, material height or color, our moisture sensors supply continuous dependable analysis with zero maintenance. A one-time calibration is all that is needed and a non-drift optical design allows the operational personnel to confidently make instant process modifications based on real-time data.

Installation of the sensor is easy and can be in numerous locations depending on your need: Primary Screen, Sump Pump, Dewatering Screen, Dryer Infeed, Dryer Dump, Belt Filter, Press, Discarded Solids, Screw, Belt, and Pipeline.


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

Dryers are far more effective and reliable when the input moisture content is kept consistent. The moisture of the sand will vary constantly as typically sand in stockpiles is between 2%-8% moisture. This variation in stockpile sand can result in dryer inadequacies which wastes energy, money and creates out of spec frac sand.

What is the 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.

Understand the Process

The IR-3000 is your best performing option when it comes to material moisture analyzers.

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