BioEnergy Moisture Applications

Create Instant Production Efficiency with Proper Moisture Control

Moisture is important in any manufacturing process, but when it comes to hog fuel, waste fiber, wood chips, pellets, saw dust, shavings, and forest waste, excess moisture can ruin products. Bioenergy applications have multiple benefits when it comes to moisture control:

  • Less Waste or Downtime on Processing Line
  • Reduced Energy Costs
  • Efficient Dryer Control Creates Large Savings
  • Increased Product Quality
  • Total Product Inspection
  • Plant Production Efficiency
  • Low Cost – Instant ROI

The critical concern of moisture content exists in Bioenergy applications as the excess moisture content can not only effect the product but also the equipment being used and the operational efficiency of the plant. Boilers are designed to operate with fuel of a limited moisture range; anything outside this tolerated range runs the risk of multiple inefficiencies, increased emissions and even error the control system. Simple implementation of moisture measurement and control can drastically increase the overall performance instantly. 


Installing a moisture measurement and control system prevents bad product due to undesirable moisture levels. Fine tuning the setup and process of the manufacturing line allows for instant improvements both in the product and in the efficiency in which it is produced. 


Multiple installation points exist for a moisture senor. For a renewable energy application, it will likely be installed over the conveyor or processing line. It is important to ensure it is connected to a sturdy support and the distance should range, on average, about eight inches from the product. By installing sensors in this fashion, the sensor can administer continuous readings during the entire application creation process, guaranteeing continuous monitoring of the process, which can be controlled manually or automatically.

The sensor can also be installed to a other conveying systems: chute, roller, chain, drag & elevator, chutes, cyclones & bins, before and after dryers or boilers, and pipelines or pneumatic conveying options.

Each renewable energy moisture sensor comes standard with an optical window to prevent flying particles from caking. We recommend cleaning the optical window from time to time to prevent damaging build-up, creating the only maintenance needed. Use your best judgment to determine cleaning dates, as the longer the particles build-up, the harder it will be to erase.

MoistTech understands the requirements to successfully produce renewable energy and our sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements are pre-set at the factory for the easiest installation process.

  • Typical accuracy is about ±0.1% moisture
  • Typical analog range is 0-10% moisture
  • Outputs can be adjusted to optimize PLC or recording requirements
