Application

  • Temperature measurement of a wide range of TC and RTD types.
  • Conversion of wide span linear resistance and potentiometer inputs to 4…20 mA.
  • 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, 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.
  • IEC 61508 : 2010 full assessment up to SIL 3 together with enhanced EMC Functional Safety testing to IEC 61236-3-1.
  • 6437xxSx is suitable for the use in systems up to Performance Level “d” according to ISO-13849
  • Meets NAMUR NE21, NE43, NE44, NE89 and NE107 compliant diagnostics information.

Mounting / installation / programming

  • DIN rail mounting with up to 84 inputs per meter.
  • Configuration via PReset using PR5909 Loop Link / HART modem, or by Asset Management tool (e.g. Pactware, AMS, HART communicator).
  • The 6437D can be mounted in zone 0, 1, 2 and zone 20, 21, 22 including M1 / Class I, Division 1, Groups A, B, C, D.
