Rugged handheld communicator improves maintenance efficiency

10 October 2016

Emerson Automation Solutions has launched the AMS Trex Device Communicator, a handheld communicator designed for use in harsh industrial environments. 

With a task-based graphical user interface built on human centered design, the Trex communicator is said to make device and loop diagnostics easy to understand and field activities easier to complete.
Protected against moisture and extreme temperatures, the unit is able to withstand the bumps and drops that come from normal use in a plant environment. The large, full-colour touchscreen display adjusts to lighting conditions and aids troubleshooting in areas where too much or too little light makes other devices difficult to read.
With intrinsic safety certifications, the communicator is certified to go anywhere that a technician can go, with no need to shut a process down or get a hot work permit. Long-life batteries ensure that the communicator keeps working even through long days.
Using its built-in Foundation Fieldbus and HART device diagnostic software, technicians are able to isolate and repair problems while the devices continue to run. Simple issues can be addressed on the spot, avoiding unnecessary interruption to production. Segment and loop diagnostic tools allow users to validate loop and fieldbus segment characteristics for easy troubleshooting. With the ValveLink Mobile app, technicians can analyse valve diagnostics results easily on the communicator’s larger screen.
