A.3 Accessories of ParticleSizeMonitorDeviceType

Figure 22 - AccessoryType of ParticleSizeMonitorDeviceType

DispersionAccessoryType is a subtype of AccessoryType. A dispersion unit allows dispersing powder. A dispersant is a liquid or gas added to a mixture to promote dispersion or to maintain dispersed particles in suspension.

LiquidDispersionUnitType is a subtype of DispersionAccessory. A liquid dispersion unit is a unit dispersing a mixture using a liquid (Water, ethanol …)

GasDispersionUnitType is a subtype of DispersionAccessory. A gas dispersion unit is a unit dispersing a mixture using a gas (Air, Nitrogen …)

SampleInterfaceAccessoryType is a subtype of AccessoryType. A sample interface is a unit allowing sample from the process line in order to perform a measurement. A sample interface accessory could be an auger, a rotational sampler, a simple probe, etc …
