Calibration Options

Transmitter-sensor matching (Callendar-Van Dusen constants), 5-point calibration

Certifications/Approvals

SIL 2/3 certified to IEC 61508 by an independent 3rd party, hazardous location, marine type, see full specs for complete list of certifications

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
