Model R Automatic Point Sampler for Bulk Solids

Point sampler for non-free-flowing products from pneumatic convey lines

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. 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.

Suitable for:
Pellets, powders, flakes and granules


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.


  • Retractable probe design isolates process pressure from sample container 
  • Sample tube and auger capture a fixed sample volume
  • Sample probe retracts from the line to avoid any restriction in the product flow between sample cycles
  • Rugged Stainless Steel construction
  • Optional sample tube materials for abrasive or non-free-flowing product 
  • Standard AC TEFC motor; DC and explosion-proof options available
  • Controllers and remote operating modules available in a variety of configurations
  • Available in a model that is conformant to ATEX Standards (through third party verification)
