Wood Chip Moisture

The importance of accurate moisture levels in wood chip production is highlighted with MoistTech’s wood moisture sensor. To avoid low quality product and wasting energy on over-drying, taking proactive steps to continually monitor moisture in wood chips can save time and money overall while increasing the plant’s efficiency levels.

The wood chips used in pulp production have natural variations in moisture. The amount of water and bone dry fiber entering the process can vary greatly. The MoistTech online analyzer can measure moisture in all of the wood chips before they enter the pulp process, making automatic feed-forward adjustments possible.

Sensor Installation

Monitor your product continually by installing our wood chip moisture gauge a few inches above the conveyor belt. Even if there are small gaps in product flow, our sensor can still give accurate readouts.

Whether you choose to monitor your product manually or automatically, our state-of-the-art sensor can help you through the wood chip monitoring process. We also have developed real-time process measurement, which you can learn more about in our sampling technology section.

Application Environment

Our wood chip moisture sensor does well even in dusty environments. If your environment is extremely dusty, you can benefit from an Air Purge System, which will significantly help in keeping your sensor free of dust and reading accurately.

You may also need to monitor your sensor if it’s installed near high-heat areas, like a dryer outlet. You can choose to cool the sensor with air or water.

Benefits of Wood Chip Moisture Gauge:

Most chip purchasers weigh wet chips, but pay chip suppliers based on dry chips delivered. To calculate the bone-dry tonnage delivered, a representative chip moisture content is applied to the wet weight of the chips delivered to the mill. MoistTech sensors can be installed at just about every location of incoming material feed; not limited to truck dumpers, stackers and re-claimers. 

Incoming wood from the yard stoarge will vary largely based on the supplier, weather and season. Installing above the conveyed material allows plant control to monitor the moisture content instantly and accurately. 

  • Less Risk of Low Quality / Wet Product
  • Energy Cost Savings
  • Less Product Waste
  • 100% Product Inspection
  • Great Accuracy – even with small gaps

We pre-set sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements at our factory. Typical accuracy is about ±0.1% moisture. Typical analog range is 0-20% moisture. The outputs can be adjusted to optimize PLC or recording requirements.
