2-wire HART 7 temperature transmitter

Application

• Temperature measurement of a wide range of TC and RTD types.
• Conversion of wide-span linear resistance and potentiometer inputs.
• Conversion of bipolar mV signals to 4…20 mA.
• Integration into asset management schemes.
• Critical applications require superior accuracy and/or sensor redundancy and drift detection.

Technical characteristics

• True dual input transmitter. The high-density 7-terminal design accepts the widest range of dual input combinations.
• Sensor redundancy – output automatically switches to a secondary sensor in event of primary sensor failure, maintaining uptime.
• Sensor drift detection – alerts when sensor differential exceeds user-defined limits for maintenance optimization.
• Dynamic variable mapping for process data in addition to the primary variable e.g., dual input features such as average, differential, and min./max. tracking.
• Groundbreaking digital and analog signal accuracy over full input span and ambient conditions.
• Extensive sensor matching, including Callendar Van Dusen and custom linearizations.
• Programmable input limits with runtime metering ensure maximum process traceability and sensor out-of-range protection.
• IEC 61508: 2010 full assessment up to SIL 3 together with enhanced EMC Functional Safety testing to IEC 61236-3-1.
• 5437xxSx is suitable for use in systems up to Performance Level “d” according to ISO-13849.
• Meets NAMUR NE21, NE43, NE44, NE89, NE95 and NE107 compliant diagnostics information.

Mounting / installation

• For DIN form B sensor head mounting.
• Configuration via standard HART communication interfaces or by PR 5909 Loop Link.
• The 5437B can be mounted in zone 0, 1, 2, and zone 20, 21, and 22, including M1.
