Model A Automatic Sampler for Bulk Solids

Point sampler for sampling granules from a screw conveyor

The Model A sampler is designed for automatic sampling of free flowing materials from screw or drag conveyors. The Model A takes a sample when a solenoid-controlled air cylinder opens a sliding gate on the sampler, then closes the gate.

Suitable for:
Pellets, flakes, granules, grain and seed


With representative sampling, characteristics of each sample match that of the entire lot or batch—so samples are repeatable, leading to accurate sample analysis data. Automatic sampling ensures a sample can be easily and safely obtained with no need for direct human interface or interference. This ensures sample integrity as well as operator safety.
