Retractable Tube Sampler.
The Model RT-RTA2 automatically samples process streams that are under either positive or negative pressure. Accurate, frequent samples from pneumatic lines or conveyors are obtainable on-stream without interruption of the pneumatic conveying system. Fully automatic, all functions are easily adjustable. Installation can be on round or flat surfaces, horizontal or vertical lines, regardless of material flow direction. Adaptable for use in gravity flow systems as well as pressurized lines, it may be mounted on rectangular or round ducts and pipelines, or through the wall of a tank or hopper. Size and frequency of samples is completely adjustable. The Model RT-RTA2 will sample granules, powders, chips, flakes, pellets, and certain liquids and slurries.
The basic Model RT automatic sampler discharges the sample by an air motor-driven auger. With the Model RTA2 the sample is ejected by a controlled jet of air. In either ejection system, the sample is completely discharged. There is no carry-over, no degradation of product. The Model RT-RTA2 sampler has a simple, maintenance-free design. There is no metal-to-metal contact between parts. Completely explosion-proof, it is all air operation.
