Sentry A Automatic Point Sampler

Part #: Sentry A

The Sentry 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. Material characteristics are not affected by the sampler because no moving parts convey the material to the sample container. Sample volume can be changed at the sampler controller.

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.

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