NIR On-Line Moisture Measurement Sensor

CM710e Moisture Gauge


The CM710e model is an online moisture sensor 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 for online moisture measurement 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. When using this online moisture sensor, efficiency improvement can result in substantial cost reductions and investment payback in a matter of months.

Operating principle

The CM710e online moisture measurement sensor works on the principle that moisture absorbs a specific wavelength of light. By pulsing light at a different known wavelength the CM710e online moisture sensor compares the absorption rate to an internal reference thus making it 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.
