To obtain a sample, the Sentry B1 sampler first cleans out the sample tube by running the auger in reverse. After purging, the auger is run in the discharge direction and the sample moves through the assembly to the discharge port. The product sampled is discharged through a flexible hose to a collection point. Sample volume can be changed at the sampler controller. The sample probe is always in the product stream.
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.
