This bundle focuses on essential tools and accessories for setting up and configuring industrial transmitters, specifically using the Emerson AMS Trex Device Communicator. It is for industrial technicians, engineers, and maintenance personnel who need to connect, diagnose, and maintain process instrumentation. The products collectively enable efficient field configuration and troubleshooting of HART-compatible devices.

Curated by The Kennel Notebook · Updated June 2026

Built for facility maintenance teams and industrial technicians who need to calibrate sensors in high-traffic or multi-use environments. Not for lab-only researchers—this shop focuses on field-hardened gear that survives drops and heavy-duty use.

Curator's pick: Trex Protective Rubber Boot

If you are working in a space where equipment gets bumped or stepped on, this boot is non-negotiable for protecting the display. I prefer it over thinner shells because the grip is better when your hands are sweaty or dusty, keeping the unit from sliding off uneven surfaces.

⚠ Worth knowing: The Trex eats through power quickly when the backlight is high; if you are in a remote area without a backup Li-Ion module, you will find yourself stuck with a dead screen mid-calibration. Also, remember that the 250 Ohm resistor is required for HART communication if the loop doesn't have it, or the device simply won't 'see' the transmitter.

How to use this together

  1. 1

    Power and Protect Your Trex

    First, ensure your AMS Trex Device Communicator is powered and protected. Install the Li-Ion Power Module for AMS Trex into the communicator. If working in harsh environments, fit the Trex Protective Rubber Boot over the device to guard against drops and impacts. This ensures your primary tool is ready and resilient.

  2. 2

    Connect to the Device

    Next, use the Banana Plug to Alligator Clip Test Leads to physically connect your Trex to the HART-compatible device, such as the Rosemount 3051S Pressure Transmitter. Attach the banana plugs to the Trex's communication ports and the alligator clips to the transmitter's test terminals. This establishes the physical communication link.

  3. 3

    Establish HART Communication

    Before powering on the Trex, if the loop resistance is too low, connect the 250 Ohm HART Resistor in series with your HART communication loop. This resistor provides the necessary impedance to ensure clear and reliable data transmission between the Trex and the field device, preventing communication errors and ensuring accurate diagnostics.

  4. 4

    Configure and Diagnose

    Finally, power on your AMS Trex Device Communicator. Use its intuitive interface to detect the connected HART device, such as the Rosemount 3051S. You can now perform tasks like device status checks, calibration, loop testing, and configuration of parameters, directly troubleshooting and maintaining your industrial instrumentation.
