For more than 25 years, Bluetooth® technology has helped create a better world through openness and connection. While most people know Bluetooth technology from the devices in their pockets, the technology has quietly become a cornerstone of industrial transformation—powering safer workflows, smarter maintenance, and more efficient operations across plants, factories, and production networks. Today, Emerson is helping accelerate that transformation through its Boundless AutomationSM vision, embedding Bluetooth connectivity directly into the instruments, control valves, and device communicators process industry technicians rely on every day to remove barriers, troubleshoot, unlock intelligence, and keep industry moving.
Asset tracking, device access, and field intelligence—without opening a single enclosure.
Industrial productivity hinges on the “hidden” workflows inside plants and supply chains: the movement of materials, the health and functionality of equipment, and the many decisions technicians make every shift—many assisted by technology. Bluetooth connectivity helps bring those workflows into the light.
Across Emerson’s measurement and control valve portfolio, instruments—such as Rosemount™ pressure, level, and temperature instruments, Micro Motion™ Coriolis meters, or the Fisher™ FIELDVUE™ DVC7K Digital Valve Controller—use Bluetooth connectivity to broadcast live status, diagnostics, configuration and calibration data directly to technicians’ mobile tools like next‑generation AMS Trex™ Device Communicator or the AMS Device Configurator app. This eliminates the need to open device housings or physically access hard‑to‑reach equipment, reducing exposure to unforgiving and hazardous environments and improving reliability by preventing unnecessary physical intervention or cover removal.
The upgraded AMS Trex Device Communicator extends this visibility even further. Its new Device Communication Plus Module delivers higher signal fidelity and faster protocol handling, improving responsiveness when working with HART®, WirelessHART®, Foundation Fieldbus™, and other smart instrumentation.
These benefits become tangible when looking at how AMS Trex and Bluetooth connectivity enhance day‑to‑day work with three of Emerson’s flagship instrumentation and final control technologies:
- Rosemount 3051 Pressure Transmitters
Rosemount 3051 transmitters enabled with Bluetooth connectivity allow technicians to pull live PVs, device status, and configuration data directly into AMS Trex from up to 50 feet away. Instead of opening the housing to clip on leads—or climbing to reach elevated transmitters—technicians can:
- Verify pressure readings and analog output remotely
- Perform configuration changes without exposing electronics to atmosphere
- Reduce time spent in hazardous or awkward locations
This dramatically cuts walk‑down time and eliminates unnecessary cover removal, improving both reliability and safety.
- Micro Motion 4700 Coriolis Transmitters
Micro Motion 4700 and 4700 ISIO transmitters enabled with Bluetooth connectivity broadcast rich diagnostic data, giving AMS Trex users immediate access to:
- Drive gain, tube health, and process‑variable stability
- Configuration parameters and calibration data
- Fault conditions, alerts, and trending anomalies
The Bluetooth technology enables wireless configuration without opening the enclosure—eliminating the need for a hot‑work permit and minimizing time spent in potentially hazardous areas. Technicians can validate meter performance, confirm process conditions, and troubleshoot issues without interrupting flow or exposing electronics to atmosphere—ideal for high‑value custody transfer, batching, and mass‑balance applications.
- Fisher FIELDVUE DVC7K Digital Valve Controllers
The Fisher DVC7K digital valve controller enabled with Bluetooth technology is one of the most powerful examples of maintenance efficiency. When paired with AMS Trex, technicians can:
- Check travel deviation, friction, and signature curves from a safe location
- Verify valve response and health without entering hazardous zones
This reduces time in the field, accelerates troubleshooting, and enables more frequent diagnostic checks—improving control valve reliability across the entire facility.
Predictive maintenance powered by wireless insight.
Unplanned downtime is one of the most expensive challenges in industrial operations. Emerson’s tools with embedded Bluetooth technology are helping teams shift from reactive firefighting to proactive maintenance—catching issues before they become failures.
The AMS Trex Device Communicator plays a central role in this shift. Its redesigned hardware architecture improves communication speed, reduces latency during device interrogation, and increases reliability when performing loop checks or validating control valve performance. With advanced diagnostics, loop testing, and configuration capabilities, AMS Trex helps technicians quickly resolve device issues, verify 4–20 mA loops, and test control valves—all with noticeably faster response times and a more intuitive user experience.
When paired with intelligent instruments, transmitters, sensors, valves, and more—Trex becomes a mobile hub for insight and action. Technicians can:
- Validate alerts without climbing structures or opening enclosures
- Act on early indicators of equipment issues
Every avoided failure protects production, reduces maintenance hours, and extends asset life. And when downtime is prevented at scale—across fleets, facilities, and global networks—the ripple effects are profound: more resilient supply chains, lower energy waste, and more sustainable operations.
Safer workflows for the people who keep industry moving.
Industrial environments are dynamic, high‑stakes places. Bluetooth connectivity is helping create safer, more ergonomic workflows by reducing the need for technicians to physically interact with hazardous equipment.
With HMIs and field instruments powered by Bluetooth connectivity, workers can perform configuration, troubleshooting, and diagnostics from a safe distance—avoiding high‑heat zones, moving machinery, and elevated structures. Emerson highlights this benefit across its measurement devices, which allow teams to limit contact with electronics in hazardous areas and reduce the need for physical access to difficult locations.
The AMS Trex Device Communicator reinforces this safety advantage. By enabling wireless access to devices, Trex helps:
- Minimize time spent in hazardous or hard‑to‑reach areas
- Reduce exposure to environmental risks
- Support safer, more efficient maintenance routes
When safety improves at the worker level, the benefits extend outward—to more stable operations, fewer disruptions, and stronger communities that rely on industrial output.
A Connected Future Built on Collaboration
The industrial world is changing fast. As plants become more automated and more data‑driven, Bluetooth technology is emerging as a unifying layer that brings people, equipment, and insight together.
Emerson’s work in this space—embedding Bluetooth connectivity into its flagship maintenance, reliability, measurement, and final control solutions; enabling wireless diagnostics; and delivering Intelligent Field innovations that extend its Boundless Automation vision all the way to the plant floor—demonstrates what’s possible when innovation meets real‑world need. The upgraded AMS Trex Device Communicator with Bluetooth connectivity, with its stronger security, certified calibration, and expanded app ecosystem is a clear example of how Emerson is equipping technicians with the tools they need to deliver faster, more accurate, and more reliable results.
These solutions don’t just make maintenance easier; they help build a world that is healthier, more sustainable, more productive, and more resilient. For more, visit our AMS Trex Device Communicator or Bluetooth Connectivity for Field Instrumentation pages on emerson.com.
