Guide to Representative Sampling
Learn the many benefits of representative sampling and get answers to your representative sampling questions
The Sentry PR Automatic Point Sampler utilizes automated sampling technology to sample within process streams. Samples can take the form of granules, powders, flakes, or pellets and are sampled from systems that both push and pull the flow.
The Sentry PR sampler's air cylinder moves a device to take the sample (called a "probe") into the process stream. Next, a flexible hose sends the bulk solids material to a collection point. Finally, the sample controller sets the amount of fluid used for the sample. The material's makeup is not affected by the sampler because no moving parts carry the sample material to its container.
This technology makes the system easier to service and improves the sampling user experience.
The representative sampling process ensures that the makeup of each sample matches that of the entire process stream. This trait is significant because it ensures that samples are repeatable and accurate.
Automated sampling technology ensures that system technicians can get a sample quickly and safely, with no need for direct human involvement or contact.
Overall, this process delivers a high-quality sample while protecting the operators' safety.
