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.

Technical 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 and runtime metering ensure maximum process traceability and sensor out of range protection.
  • IEC 61508 : 2010 full assessement up to SIL 3 together with enhanced EMC Functional Safety testing to IEC 61236-3-1.
  • 5437xxSx is suitable for the use in systems up to Performance Level “d” according to ISO-13849.
  • Meets NAMUR NE21, NE43, NE44, NE89, NE95, NE130 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 5437A can be mounted in zone 2 and 22 / Class I, Division 2, Groups A, B, C, D.
