Model RB Automatic Strip Sampler for Bulk Solids

Strip sampler for free-flowing and non-free-flowing materials from a variety of process applications

The Sentry® RB automatic strip sampler automates sampling of dry free-flowing and non-free-flowing materials such as granules, powders, flakes or pellets from gravity chutes and hoppers. The RB takes a sample when a solenoid-controlled air cylinder extends a slotted sampling tube into the process line. A sample collects by a gearmotor-driven auger 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.


  • Discharges material during entire sample cycle
  • 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)
