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
