This bundle focuses on the tools and accessories necessary for calibrating control valves using the Emerson AMS Trex Device Communicator. It is for industrial technicians and engineers responsible for maintaining field instrumentation. The products collectively enable efficient setup, calibration, and troubleshooting of smart valve positioners and other field devices.

Curated by The Kennel Notebook · Updated June 2026

Built for technicians managing industrial valve stations in environments where sensitive equipment must survive rough handling and frequent setup changes. Not for desktop hobbyists—this shop focuses on rugged, field-ready hardware that handles the physical abuse of a busy facility floor.

Curator's pick: AMS Trex Device Communicator Plus Communication Module

This is the backbone of the system; unlike cheaper handhelds, the Trex handles power surges better when you're hooking up to a live loop in a cramped cabinet. It is the only unit I trust to stay synced when the vibration and ambient noise make other communicators drop the signal.

⚠ Worth knowing: If you are working with older analog systems without a HART-compatible positioner, the Trex is overkill and won't communicate without the 250 Ohm resistor included here. Also, the battery life drops significantly in high-heat environments, so always keep a spare power module on the charger.
