II. GENERAL INFORMATION
2.1 System Description
The TD Sampler is designed to collect a representative sample of granular, pellet, or other materials from the end
of a belt conveyor. Figure 2-1 illustrates a typical TD Sampler application.
Sample collection is initiated in response to either an operator's manual command or a signal automatically
generated by controller logic, usually time-based but which could also be volume or quantity based. A sample
cycle begins when an electric motor drives the slotted sample cutter through the product flow to collect a sample of
the material. The sample is pnuematically withdrawn from the sample pelican via a SD sample delivery system.
The sample cutter, when at rest, is situated under one of two dust seals that seal the sample cutter. The sample,
flowing via gravity from the SD system, will then be routed to a sample divider or directly to the desired sample
collection point.
