Sentry GA Automatic Cross-cut Sampler

Sentry GA Automatic Cross-cut Sampler


Product Description

The Sentry Model GA sampler is a cross-cut sampler designed for automatic sampling of free-flowing, non homogeneous products from square or round gravity chutes. The GA takes a sample when an air-actuated “pelican-type” head moves across product flow in spout and collects a representative sample to the discharge point.

The material sampled is discharged through a flexible hose to a collection point. 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, powders, flakes, granules, grain, seed and slurries
