NIR on-Line Moisture Gauge for Mineral & Bulk Materials

CM710e Moisture Gauge


The CM710e model is industrial moisture gauge specifically designed to meet the needs of companies manufacturing powders, coarse or fine particles, concentrates, slurries, pastes, flakes, granules and other similar products. Using near infrared (NIR) non-contact principle it is suitable for many types of continuous processes and will provide real-time moisture measurements that can be used to control the process, monitor product quality and warn operators if the process is moving out of specification, thereby increasing yield and improving quality. Efficiency improvement can result in substantial cost reductions and investment payback in a matter of months.

Operating principle

The CM710e works on the principle that moisture absorbs a specific wavelength of light. By pulsing light at a different known wavelength and comparing the absorption rate to an internal reference it is possible to determine exactly by how much each wavelength is being absorbed. Using high-speed signal processing the algorithm converts the infrared signals into an output that is proportional to moisture content by means calibration curve. The measurement in unaffected by changes in process conditions such as particle size, product height temperature, ambient lighting and humidity changes.
