Moisture Measurement in Paper and Pulp Manufacturing

Effective moisture measurement is critical in paper and pulp production. High or low moisture levels can compromise product quality, reduce efficiency, and increase the risk of equipment damage or accidents. Accurate and reliable moisture monitoring equipment is, therefore, essential for optimizing operations and ensuring consistent product quality.

Water Damage Prevention

Excessive moisture in paper and pulp can lead to water damage, resulting in reduced product quality, increased production costs, and potential safety hazards. Moisture monitoring equipment can detect elevated moisture levels early on, allowing operators to take prompt corrective actions to prevent water damage and its associated consequences.

Types of Moisture Measurement Equipment

Several types of moisture monitoring equipment are commonly used in the paper and pulp industry:

  • Capacitance sensors measure moisture content by detecting changes in the capacitance of a material. This method is commonly used for measuring moisture in wood pulp.
  • Microwave sensors emit microwave radiation and measure the amount reflected back, which is affected by the moisture content of the material being tested.
  • Near-infrared (NIR) sensors use NIR light to determine moisture content by measuring the absorption and reflection of specific wavelengths.
  • Contact moisture meters are inserted directly into the material and measure moisture content through electrical conductivity or dielectric properties.
