b'QUALITY MEASUREMENT & CONTROLon an infrared sensor installed on the process using special Experion MX QCS displays supporting field calibration of all sensors.Honeywells MXIR transmission infrared sensor uses a unique, but well proven, optical geometry that both increases sensitivity to measured components, such as fiber and water, while also minimizing measurement error resulting from changes in the sheets infrared energy scattering power. This geometry results in improved accuracy, typically requiring only one calibration for all grades produced on a tissue machine.Here are specific examples of the performance that can be achieved with Honeywell solutions.Honeywells tissue crepe sensorFigures 3 & 4. The graphs above show a comparison of basis weight profiles provided by an air-mounts in an enclosure similar to anygap-temperature-compensated nuclear sensor and an MXIR transmission infrared sensor. It is easy to see that the transmission IR measurement of basis weight is easily capable of replacing other scanning sensor. The sensora nuclear sensor solution.
