PR electronics 5437D2S 2-Wire HART 7 Temp Transmitter, Dual Input

PR electronics, 5437D2S, 2-Wire HART 7 Temperature Transmitter, Dual Input, SIL

Features

• RTD, TC, potentiometer, linear resistance and bipolar mV input
• True dual inputs with sensor redundancy and drift detection
• Wide ambient operating temperature of -50 to +85°C
• Total accuracy from 0.014%
• 2.5 kVAC galvanic isolation

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

Characteristics

• True dual input transmitter. High density 7-terminal design accepts the widest range of dual input combinations.
• Sensor redundancy - output automatically switches to 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.
• Meets NAMUR NE21, NE43, NE44, NE89 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 5437D can be mounted in zone 0, 1, 2 and zone 20, 21, 22 including M1 / Class I, Division 1, Groups A, B, C, D.
