Sentry RX Automatic Strip Sampler

Part #
Sentry RX

The Sentry Model RX Sampler takes automated strip samples by grabbing several strips of the same size of loose materials from drop chutes, bins, hoppers, pipes, or air slides. This approach can also take samples from dilute (non-dense) streams in systems that use air to move the materials through the piping in any direction.

The RX takes a sample when an air cylinder, controlled by an electrically charged coil called a solenoid, extends a sampling tube into the process line. While in line, the tube continuously takes samples and sends them to the collection point.

A process called representative sampling ensures that the makeup of each sample matches that of the entire process stream. This trait is significant because it ensures the samples are repeatable and accurate.

Automatic sampling ensures that system technicians can get a sample quickly and safely, with no need for direct human involvement or contact. This process delivers a high-quality sample while protecting the operators' safety.


  • Compact and low maintenance
  • Designed to eliminate the product becoming ruined
  • No moving parts in moving the sample to its container keeps the makeup of the product consistent
  • Stainless steel construction, a strong and durable material that resists corrosion from water
  • More durable sample tube materials are available to service harsh or non-free-flowing fluid
  • Controllers and remote operating modules are available in a variety of configurations. These components improve the user experience and allow the operator to control the sample from further away
  • Available in a model that follows the industry standard ATEX (through third-party verification)
