6437A 2-Wire HART 7 Temperature Transmitter

Brand: PR Electronics

  • RTD, TC, potentiometer, linear resistance and bipolar mV input
  • Single or 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
  • Full assessment to IEC61508 : 2010 for use in SIL 2/3 applications
Features
  • 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.
  • Meets NAMUR NE21, NE43, NE44, NE89 and NE107 compliant diagnostics information.
