Rosemount 644 Temperature Transmitter is designed for use in control applications
The Rosemount 644 temperature transmitter is designed for use in control applications where the loss of the temperature points may be detrimental. These highly accurate Rosemount 644 temperature transmitters are available in a variety of mounting styles, field housings, and communication protocols to meet your demanding installation requirements.
Each Rosemount 644 temperature transmitter is a 2-wire design providing either a 4-20 mA/HART or a completely digital FOUNDATION fieldbus ouput. Each unit can be configured for a variety of sensor inputs: RTD, themocouple, millivolt, or ohm. The advanced Rosemount 644 temperature transmitter powers PlantWeb by communicating important temperature diagnostics and PlantWeb alerts to ensure process health and enable economical single-sensor architecture.
Entering the temperature-resistance profile specific to the RTD sensor into the Rosemount 644 temperature transmitter results in transmitter-sensor matching. This eliminates the sensor interchangeability error, which can improve accuracy by up to 75%. The integral LCD display provides local indication of temperature measurement and diagnostics for immediate and accurate verification or process conditions.
Meeting the NAMUR NE 21 recommendations, the Rosemount 644 temperature transmitter ensures top transmitter performance in harsh EMC environments. In addition, the Rosemount 644 HART transmitter meets NAMUR NE 43 and NE 89 recommendations.
The Rosemount 644 temperature transmitter offers great mounting flexibility. The DIN A style head mount transmitters fits a variety of housings for remote transmitter mounting and can be integral or remote mounted to a sensor. The compact rail mount style is great for DIN rail mounting in the tight spaces of a crowded control room.
Features User-selectable inputs 4-20 mA HART or FOUNDATION Fieldbus output Optional five-digit integral LCD display Input/output isolation tested to 500VAC RMS 707VDC @50/60Hz Head mount or rail mount
