Rosemont 644R temperature transmitter
The Rosemont 644 temperature transmitter is designed for use in control applications where continuous temperature measurement is required and temperature loss may be harmful. This Rosemount 644 temperature transmitter is very light and a variety of communication protocols are available to meet your needs.
Each 644 temperature transmitter has a 2-wire design that offers 4-20 mAh or a fully digital FOUNDATION field bass field. Each unit can be adjusted for sensor input types: RTD, themocouple, millivolt or ohm. With the Rosemount 644 PlantWeb دما Temperature Transmitter, it utilizes process health and the ability to use an economical single-sensor architecture by making important connections to temperature detection and PlantWeb warnings.
Entering the temperature resistance specifications for the RTD sensor on the Rosemount 644 temperature transmitter will match the transmitter sensor. This eliminates the need to replace the sensor, which can improve accuracy by up to 75%. The integrated LCD display provides a local indicator of temperature measurement and detection for immediate or accurate confirmation or process conditions.
Following the recommendations of NAMUR NE 21, the Rosemont 644 temperature transmitter ensures the superior performance of a temperature transmitter in harsh EMC environments. In addition, the Rosemount 644 HART temperature transmitter meets the recommendations of NAMUR NE 43 and NE 89.
The Rosemount 644 temperature transmitter offers flexibility in installation. The DIN A Lightweight Monitor Transmitter is suitable for a variety of remote transmitter installations and can be a single sensor or a remote integrated sensor. Compact rail installation style is excellent for installing DIN rail in tight spaces of a crowded control room.
