IG710S & SR710S Sensors
NIR on-Line Moisture Measurement Sensor for Coating & Converting Industries
The IG710S and SR710S sensors are for online measurement of coatings, laminates and moisture. The sensors are specifically designed to meet the needs of converting industry for measuring the coatweight thickness and moisture. 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 sensor, improves process efficiency resulting in substantial cost reductions and investment payback in a matter of months.
The IG710S & SR710S online measurement sensor works on the principle that water and organic products, such as coatings, absorb near-infrared light (NIR) at specific wavelengths. When exposed to NIR light, a product will absorb a proportion of this energy depending on the active constituent that is present. By pulsing light at a different known wavelength, the 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 and coatweight thickness by means calibration curve. The measurement is unaffected by changes in process conditions such as particle size, product height temperature, ambient lighting and humidity changes.
