The Sentry Model SA sampler takes a cross-cut sample of free-flowing materials from vertical spouts and chutes. The SA takes a sample when a solenoid-controlled pneumatic rotary actuator swings a pelican type diverter on an arc across the entire product flow. The diverter captures a sample then discharges it through the pelican tube. The discharge tube is on the axis of rotation and is parallel to the material flow. The diverter is under a dust seal when at rest, keeping the fines from flowing into the diverter. The sampler is controlled by a Sentry automatic control system, allowing the operator to program the time between samples.
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.
