## A.1 Overview

Analyser types which fall under the category of particle size monitor devices can extend the ADI model further by defining Parameters and/or subtypes of ParticleSizeMonitorDeviceType, AccessoryType, AnalyserChannelType or StreamType.

In the simplest case, no subtypes need to be defined and the Parameters can be exposed on existing ParticleSizeMonitorDeviceType Object or one of its components.

The following is an example of how a particle size monitoring device could extend the ADI Information Model by further refining definition of an Accessory and by defining new Parameters on ParticleSizeMonitorType.
