The I-S Model PS sampler is designed to provide repeatable and representative samples and can be left totally unattended. Key features include the following: All product contacts are Type 304 stainless steel; seals will withstand temperatures up to 550°F and pressures to 125 psig; the machined auger has no crevices or product hang-up points; tolerance between the tube and auger is 0.003 ensuring total cleanout of product; a limit switch ensures that the sampler will complete its cycle; a 5-in. bore cylinder is standard; sizes are available up to 14-in. round. The device can be used to sample microscopic powders to large granules and pellets, and a variety of materials of construction are available. It can be used in gravity flow, positive and negative lines, and dilute and dense phases.

Air-Powered, Retractable Sampler
The Model RTA-2S is an air-powered retractable tube sampler for sampling granular products from a gravity or pneumatic conveying line. Fully automatic, the sampler delivers accurate, frequent samples with no metal-to-metal contact between parts. The unit ejects the sample with a controlled jet of air, and the sample tube is out of the process stream when at rest. The sampler has a polished Type 316L stainless-steel sample tube that is quickly removable from the sampler for easy cleaning.

Automatic Sampler for Pneumatic Conveying
The Model PR is designed for sampling bulk solids such as pellets, cement, chemicals, resins, and powders from dilute- and dense-phase pneumatic transfer lines. Features include an isolated sample tube that captures a fixed sample volume; rapid cycling that acquires a large volume of sample over a short period of time; a tube that retracts from the line to avoid any restriction in the product flow between sample cycles; and a design that can eliminate degradation of product.
