Rosemount 644 Temperature Transmitter Chinese price
Introduction of Rosemount 644 Temperature Transmitter
Engineered for versatility, the Rosemount 644 Temperature Transmitter is available with HART™, FOUNDATION™ Fieldbus or PROFIBUS™ protocols in head, field or rail mount styles and a variety of enclosure options. By adding a Local Operator Interface (LOI), you can update your transmitter configuration in the field without tools. For diverse application requirements, this transmitter includes diagnostic capabilities, such as Hot Backup™ capability, sensor drift alert and thermocouple degradation.
Features:
- Extremely versatile temperature transmitter available in HART™, FOUNDATION™ Fieldbus or PROFIBUS™ protocols
- Diverse mounting configurations including head, field or rail mount with many enclosure options
- LOI option eliminates the need for special configuration tools (i.e. field communicator) for ease-of-use
- Transmitter-sensor matching with Callendar-Van Dusen constants reduces total measurement error
- Hot Backup™ capability and sensor drift alert with dual sensors ensure measurement integrity
- Thermocouple degradation diagnostic monitors thermocouple health to detect degradation before failure
- Minimum and maximum temperature tracking observes temperature extremes for easy troubleshooting
- Device dashboards provide easy interface for simplified device configuration and diagnostic troubleshooting
