Temperature transmitter

Features a modular design can easily be customized for any application

Emerson Process Management has released an enhanced Rosemount 644 Temperature Transmitter, featuring ease-of-use improvements and a modular design that enables customised functionality at each process point.

"We are excited to unveil this innovative addition to Emerson’s complete portfolio of temperature measurement solutions," said Nick Grant, Emerson Process Management’s vice president of worldwide temperature. "The 644 transmitter’s modularity, along with its comprehensive diagnostics, unmatched accuracy and proven reliability, gives users valuable clarity into their process so they can achieve much greater efficiency, reduce business and safety risks, and consistently meet production and quality targets."

The modular components of the Rosemount 644 Temperature Transmitter give users the flexibility to truly maximise their instrumentation investment. Users can easily customise the base model to fit any application, so they only purchase what they need, and have more to spend on additional measurement points. A thoughtful, human-centred design makes the device easy to wire, with clear, straightforward diagrams and improved accessibility. A simplified transmitter interface and second sensor input help to minimise installation and maintenance time, and increase productivity.

Key capabilities now available in the 644 include Hot Backup™ and Sensor Drift Alert, which ensure seamless performance in the event of a sensor failure, and advance notification of potential issues so users can be proactive and maintain total process control. The enhanced 644 is SIL2 safety certified to meet any safety application requirement and users receive full documentation for easy SIS compliance. The new Local Operator Interface (LOI) option is provides a cost-effective and convenient solution for on-the-spot commissioning and in-field configuration. With its intuitive menu structure, users have immediate access to the information they need to troubleshoot issues, validate measurements or make adjustments to ensure efficiency and reliability.

For over 50 years, Emerson’s innovative Rosemount temperature portfolio has provided reliable temperature measurement to the process industry.
