New Rosemount 644 Temperature Transmitter Pt100 4-20ma Hart
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.
