The Rosemount 644 temperature transmitter is the most cost-effective temperature transmitter in the Rosemount transmitter temperature series. It is versatile, supporting HART®, FOUNDATION™ fieldbus, or PROFIBUS® protocols, and offers top, field, or rail mounting styles along with various housing options. Today, the technical editor from Shaanxi Huibo Electromechanical will explain it in detail.What functions does the Rosemount 644 temperature transmitter support?
1. The Rosemount 644 head-mounted and field-mounted temperature transmitters support the following functions:
1. Configurable HART using selectable HART version functions (Version 5 or Version 7).
2. Accepts 1 or 2 channel inputs from various sensor types (2, 3, and 4 wire RTD, thermocouples, mV, and Ohm).
3. The electronic components of the compact transmitter are fully encapsulated in protective silicone material and wrapped in a plastic housing, ensuring long-term reliability.
4. Optional safety certification options (IEC 61508 SIL 2).
5. Optional enhanced accuracy and stability performance.
6. Optional LCD display with an extended temperature rating between -40 to 85°C.
7. Optional advanced LCD display with a local operator interface (LOI).
8. The Rosemount 644 head-mounted transmitter can use two types of housing materials (aluminum and stainless steel) and various housing options, providing installation flexibility in various environmental conditions. The Rosemount 644 field-mounted transmitter uses an aluminum housing.
9. Special dual sensor features include Hot Backup™, sensor drift alarm, first good value, temperature difference, and average temperature measurement, supporting not only analog output signals but also simultaneous four-variable measurement outputs.
10. Other advanced features include thermocouple aging diagnostics (which can monitor the health of the thermocouple) and tracking of minimum/maximum process and transmitter temperatures.
2. The Rosemount 644 rail-mounted temperature transmitter supports the following functions:
1. 4-20 mA/HART protocol (Version 5).
2. Accepts 1 channel sensor input from various sensor types (2, 3, and 4 wire RTD, thermocouples, mV, and Ohm).
3. Fully encapsulated electronic components ensure long-term reliability of the transmitter. The following documents list the complete set of compatible connectors, sensors, and thermowells provided by Emerson.
