Particle size can be determined by light scattering (e.g. Focus Beam Reflectance Measurement, Laser Diffraction) or other Methods. This type of analyser can be used to implement particle monitoring technique for in-line real-time measurement of particle size. A wide range of industrial process control applications are therefore possible such as the online control of crystallizers.

ParticleSizeMonitorDeviceType defines the general structure of a ParticleSizeMonitorDevice Object.

Subtype of the AnalyserDeviceType defined in 5.2.1.1

The term ParticleSizeMonitorDevice refers to an instance of ParticleSizeMonitorDeviceType ObjectType as defined in Table 53.

All ParticleSizeMonitorDevice have Attributes and Properties that they inherit from the AnalyserDeviceType.

ParticleSizeMonitorDeviceStreamType defines seven mandatory FunctionalGroups described in5.2.3.1: Configuration, Status, AcquistionSettings, AcquisitionStatus, AcquisitionData, ChemometricModelSettings, Context. Parameters exposed by an Stream of a ParticleSizeMonitorDevice should be organized by those FunctionalGroups based on their meaning.

Table 54 describes the Parameters that are organized by the AcquisitionData FunctionalGroup of a ParticleSizeMonitorDeviceStreamType.
