Guide to Representative Sampling
Learn the many benefits of representative sampling and get answers to your representative sampling questions
The Sentry R automatic point sampler automates sampling of free-flowing materials such as granules, powders, flakes or pellets from positive or negative pressure systems. A point sampler captures samples from a point in a process stream and often is used when the material is homogeneous.
To obtain a sample, the Sentry R sampler's air cylinder moves a sample probe and auger into the process stream. After the sample has been captured through the aperture and the sample tube retracts, the auger conveys the sample to the discharge point. The sample material is discharged through a flexible hose to a collection point. 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.
