Sentry RB Automatic Strip Sampler

Part #
Sentry RB

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.

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.

Benefits

  • Discharges material during entire sample cycle
  • Sample probe retracts from the line to avoid any restriction in the product flow between sample cycles
