Learn the many benefits of representative sampling and get answers to your representative sampling questions
The Sentry G automatic cross-cut sampler automates sampling of dry free-flowing materials such as grain, granules, powders, flakes or pellets in vertical or inclined chutes. A cross-cut sampler captures a cross section of an entire material stream and is used in situations where material segregation exists.
To obtain a sample, the Sentry G sampler's air-actuated pelican type head moves across the process flow in the chute and deposits it at the discharge. 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.
