Materials such as salt, cement, fertilizer, alumina, gypsum, and food products are sampled from process streams. An auxiliary top body port enables air ejection of non-free-flowing materials.
An air cylinder extends a single plunger into the process material, then immediately withdraws, carrying a fixed amount of sample trapped in an annular ring between plunger seals. Process or flow ports are always closed, preventing leaks or product loss. There are no tubes or passages to become clogged. The gravity-discharged sample is transferred directly to a closed container.
Sentry engineers, manufacturers and services components for collecting representative samples of steam, water, gas, liquid, slurry and bulk solids. This enables analytical and operational professionals to gain samples safely and simply, and with repeatable results.
