Common Applications for the PR 5437A HART Temperature Transmitter

• 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 requiring superior accuracy and/or sensor redundancy and drift detection.

Technical Characteristics of the PR 5437A

• 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 the 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 minimum / maximum 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 and 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.
• The 5437A meets NAMUR NE21, NE43, NE44, NE89, NE95, and NE107 compliant diagnostics information.
