Emerson Smart HART Temperature Measurement Sensor Rosemount 644 Temperature Transmitter

The Emerson Rosemount 644 Temperature Transmitter is a smart, HART-enabled device designed for precise temperature measurement in industrial environments. Engineered with advanced diagnostics, it monitors sensor health, loop integrity, and process conditions to minimize downtime. Customizable for RTDs, thermocouples, and millivolts, this transmitter delivers reliable performance in harsh applications like chemical processing, power generation, and oil & gas.

• Smart Diagnostics: Continuous sensor health checks (drift, resistance, wire breaks) with loop integrity monitoring and event logging.
• Flexible Configuration: Supports RTD (Pt100), thermocouple (Type J/K/T/E), and mV inputs with HART 7 protocol for remote calibration and firmware updates.
• Durability: IP67/NEMA 4X housing withstands moisture, vibration, and corrosion. Operating temperature range: -40°C to 85°C (-40°F to 185°F).
• Accuracy: ±0.15°C (Pt100 RTD) for precise process control.

• Industries: Petrochemicals, pharmaceuticals, power plants, food processing.
• Processes: Reactor temperature control, distillation, HVAC systems.
• Environments: Explosive atmospheres, corrosive media, extreme temperatures.
