Emerson

Emerson is a global technology and engineering company with a significant presence in process automation and field instrumentation. Their Automation Solutions segment manufactures a broad range of field instruments, communicators, and control devices used across process industries including oil & gas, chemical processing, power generation, and water treatment.

Among the most recognized products in their field instrumentation portfolio are the 475 Field Communicator and the AMS TREX Device Communicator — handheld devices that connect to intelligent field instruments using the HART protocol, FOUNDATION Fieldbus, and PROFIBUS. These tools allow technicians to configure, calibrate, and diagnose field devices without removing them from service, making them essential for plant maintenance and commissioning operations.

Key Product Lines

• HART field communicators (475, AMS TREX): handheld devices for configuring and diagnosing HART-enabled field instruments
• Flow measurement: Coriolis, magnetic, vortex, and differential pressure flowmeters
• Pressure instruments: transmitters and gauges for process pressure, differential pressure, and level measurement
• Temperature measurement: thermocouples, RTDs, and temperature transmitters for industrial processes

Industries Served

Emerson process instruments are used extensively in oil & gas production and refining, chemical and petrochemical plants, power generation, water and wastewater treatment, pulp and paper, and food & beverage processing. Their HART communicators are essential tools for instrument technicians and process engineers during plant maintenance, calibration, and commissioning activities.
