Sentry COS Sampler Controller (ATEX Rated)

COS Controller - ATEX Rated

The Sentry COS controller is a dedicated logic control and alarm system designed to integrate with any Sentry ISOLOK API cell or probe sampler and its accessories. The controller is programmable and operated though a touch screen interface or remotely via Modbus. By accepting a 4–20 mA flow signal, the controller paces the sampling action proportionately to the flow rate.

The Sentry COS controller integrates common auto-sampler accessories for a purpose-built solution. The menu driven operator interface allows for quick access and navigation to all system parameters for easy system status monitoring. Match your process to the controller features for batch sampling, flow proportional or time proportional sampling. The weigh and level system allows for tare, continuous monitoring and logging of performance factor calculations.
